[@phomchick]

The absolute best part of this video is that Nelson has an oscilloscope hooked up to a speaker to show just how little music requires more than one watt.

[@melbguy1]

My next amp will have conservatively 60 watts Class A into 4 ohms which my speakers will only ever use up in micro- second bursts for big dynamic peaks.

[@xfilesfoxisdead7979]

Im using less than 1 watt to my near Field listening. Sometimes its even less than 0.5 W

[@johnbewty]

This is both true and misleading at the same time. 1W is plenty of power to let you listen at 75-85dB and it can sound great. This "first watt" is most crucial, just like Nelson says! But, it's the dynamic peaks that really make music come alive and pull you in emotionally. You need 20-30dB of momentary headroom for that. To achieve that, you either need very sensitive speakers, or lots of power. For a low-power amp, you need high sensitivity speakers - think 95db/watt or higher and you may still find the bass lacking. For speakers with medium or low sensitivity, 100-200W of peak amplifier power is not overkill.

[@martinda7446]

It's speaker sensitivity which should be taken note of as well as average amplifier power. As 3db is a doubling in power. An extreme case would be a small low sensitivity sealed box type of 82 db sensitivity next to a big 108db horn driven by one watt - You would need to push the lower sensitivity model with about 500 watts average for same pressure level.

[@MichelLinschoten]

Yah as it depends on you speakers too ... I can tell you that my magnepans don’t do nothing much of interest on 1 watt

[@tsamplifiers6493]

I'm a fan of Mr. Pass. I've owned his 400A, CAS2, FET9 and 10 and S300II. Most remain unsurpassed today. I admire his passion, creativity, complete honesty and integrity in promoting his companies and products. His Pass products are statement, daily drive exotics. That their performance is equaled with fewer output devices, smaller peak oriented power supplies, basic chassis and minimalist, decorative metal work is beside the point. They are for true audiophiles like myself who have had everything, but want to settle down with something beautiful, original and unsurpassed in every detail. Nelson Pass could be far wealthier. But he would never build companies and sell them at their peak (Henry Kloss) to offshores leaving workers unemployed. I am grateful to have owned some of his earlier, still working components. Rock on Nelson!

[@Waitaminutesilly]

No fancy speaker cable, power cord, and power conditioner! Oh and nice imagery of picture of Albert in the background next to Nelson at the end of the video!! This video really inspired for me to get XA30.8 amp!!!

[@jimomertz]

The fact that he has the picture of that first transistor, and treasures it, tells me that he respects the enormity of that invention and how it changed the world. I wonder if he had to match those 1000 JFETs. It would take forever!

[@FOH3663]

He hand matched, and hand soldered all of them.

[@miguelbarrio]

Thank you Nelson and Steve! The 1,000 JFET amp and the pic of the first transistor are to die for!!!

[@wesw9586]

@Mdmchannel I wonder if there is even a decent equivalent part out there today? A lot of Nelsons goodies are made with some pricey to downright unobtanium level FETs and transistors.

[@deserteddrake]

@Mdmchannel to be able to drive speakers!

[@newdeep19]

Thank you Nelson and Steve for this wonderful video.

[@512bb]

This video is proof you never stop learning as I had no idea Nelson was such a Frank Zappa fan which is a close subject in my life. My uncle was Frank Zappa's manager & he was responsible for getting me into audio as Frank bought me my very first pair of speakers back in 1978 ( JBL 4311b ) which I still own & there started my journey. As a side note I think people would be surprised to know what a brilliant & deep thinker Frank really was, he was truly something special aside from his musical .talents, what a terrible loss that he was taken too soon.

[@deevnn]

Terrific interview of a an incredible innovative genius.

[@blackwaterdogs4256]

There is something very special about being in the presence of greatness. I have enjoyed that privilege several times, it leaves a lasting impression. As always, thanks for sharing!

[@TheDistrict644]

Black Waterdogs I would think. Walking history!

[@mrGoesto11]

Cool gear, Nelson Pass is such a nice guy. One day I hope to own a piece he's made.

[@audioheadcase1938]

Love, love, love for Nelson Pass - I was fortunate enough to purchase a set of Threshold SA/6e amplifiers that were built for Rene Besne, Mr. Pass's partner at Threshold. They are truly one of a kind and they will stay in the family forever. Incredible powerhouse amplifiers that have a sweet, delicate sound. The are a great match with the Magnepan 3.6R . Thank you Mr. Pass for creating the perfect key that unlocks my Magnepan's true potential ! What a cool room ...

[@rickg8015]

What I like about Nelson Pass is he hasn’t abandoned his DIY roots.. He thrives on it.. He knows the good shit too, from Corman to Giger to Zappa.. That discrete amp with tiny J-fets is special indeed.

[@georgealvarez8967]

An Honor indeed. Thank you both very much. The pride here is wonderful to see !

[@DaleCarterDrives]

I think it is awesome that a legend like Nelson Pass uses gear in his room that "audiophiles" wouldn't use to block open a door. :-)

[@morris7025]

Thanks Steve! You're going to have a hard time topping this series! : )

[@MangoZen]

Thank you Steve. A wonderful and interesting video. Never imagined I would get to experience Nelson Pass’ listening room. Awesome!

[@SteveGuttenbergAudiophiliac]

This is Part 4 of a 6 Part series. Links for Parts 1 to 3 are in the description box below the video. Parts five and six will post over the next two Saturdays.

[@salvadorrodenas3071]

Steve I'm 🤤

[@raymondleggs5508]

I like how he is satisfied with a sony multi disc changer when most audiophiles would balk and he doesent use expensive wires despite the fact he came up with more than half the concepts still used in hifi.

[@somsci]

Ditto: Thank you Steve (and Nelson) for this wonderful series of interviews.

[@Renrondog]

PAPA! One of the nicest people I've ever met. Very dry sense of humor. We love you Papa!

[@christophernoto]

Love this man. Well done, Steve! Many thanks, as always.

[@wesw9586]

Nelson is one of my heroes! Thanks for this series, Steve. Pretty cool to get in the lair of the man, the myth, the legend. It's just about what I would have expected with the o-scope and the homebrew speakers.

[@DwightMS1]

Nelson has the face of a truly happy man.

[@myplaguesify]

nothing fancy just pure great products of genius and humble guy

[@rj0640]

Nelson Pass is a mensch. I am a big fan of him, his attitude toward business and his work. I am a Pass Labs fan and an even bigger First Watt fan. Steve and Nelson, thanks for this great series of interviews. As was said already, you will be hard pressed to top this.

[@diegodioli3758]

Great interview! Thanks to Both Steve and Nelson. Loved the entire series.

[@69Muscle]

Awesome! Thank you Nelson and Steve.

[@nesutoneko]

This is, by the widest of margins, the greatest audio room I have ever seen. ❤️

[@socksumi]

One of the great amp designers of our time.

[@pablon7444]

Thanks for this video. Mr. Nelson Pass is a great guy, big sympathy and respect. Even though he is a busy man, he always had time to reply to my emails :)

[@brandonenn7052]

Thank you, Nelson for the years of music enjoyment. Your contribution to the Adcom GFA 555’s has kept my Magnepans sounding detailed, amazing and musical for decades. Recently, I have been considering upgrading. The amps sound wonderful in bridged mono mode. But I am downsizing and in a smaller apartment now and wanted to go to a single stereo amp. Considering pass labs and calling local dealers in my area. None carry the Pass labs brand, but every single person said that it was great gear and how nice a man Nelson is. That is a real compliment. People who’ve met him always seem to Say how nice a person he is. For someone of his accomplishments, it would be very easy to be arrogant and dismissive. But he’s like a kid showing his hobbies and projects. Good for him. There is far too much snobbery in the audiophile world. Just enjoy music and appreciate the luxury of all this great gear. I’ve hear $100k systems and $1000 systems. As long as you’re enjoying music, the price does not matter.

[@tbonez5906]

Just a wonderful presentation, very informational and I'm in awe... love your channel, demeanor and knowledge Steve, keep up the videos I know you mad over 700, keep em coming!

[@Aswaguespack]

It’s been posted earlier that TODAY is Steve’s Birthday. So a big HAPPY BIRTHDAY to you Steve on your birthday. A few days ago I made 66, so I am old enough to understand the society we grew up in and have such fond memories of. Have a most wonderful day Steve. Hope you get a lot of cool new shirts today!! 😂

[@jarodreddig63]

Absolutely fascinating!! I want more Pass!!!!!!

[@markw5497]

Very nice, best 10 mins of my week!

[@janpedersen8376]

Wonderful to see and hear Mr Pass. I have been listening to music all day using his A40 Class A amp that i build a few decades ago and it still works wonderfully! Circuit was in Audio Amateur back in the 70’s i believe.

[@endnami]

this was rather amazing. I almost didn't see this video in the feed.

[@guilhermedealmeida2299]

This is the *listening room* of the great man. The high level speciallist in sound and electronics. We all now he knows a lot, a lot in sound reproduction. But can you see the bass traps, can you see the absorbers? Can you see the diffusers, can you see any signs of room treatment? This is his personal listening room remember? It seems we are too much obsessed with room treatment. Certainly we can optimize, avoid bad procedures but without too much obsession...

[@mariosupa4027]

Great video Steve. Mr. Pass seems to be a very humble and gentle man. My first separate amp was the Adcom GFA-555 & matching preamplifier later a Threshold T400 I've never had the honor of owning a Pass Labs or First Watt. Again awesome video Steve !

[@marywiseman-shuffield6474]

Recently retired, I am having a blast restarting my DIY spirit. Sitting now, across from my SET amp and OB speakers using Beyma 12-inch full-range. I love simple stuff! Hats off to Nelson Pass! Thanks Steve, for all the interesting videos!!

[@michaelbullock9079]

Love this guy, would love to meet him some day. He is so real and passionate about his work, just like Andrew Jones!

[@henriksrensen3220]

[@edwardbarr1533]

I love my Threshold S 350e 27 years of Stirling service ,its driven a few different speakers,all beautifully. Though I cannot afford to replace it ,very few better it , only the Pass Labs . Mr Pass like most touched with genuine greatness is a pleasure to listen to. A most wonderful video.

[@delvalle9256]

Wow 😮. Thanks 🙏 for this Steve.

[@vcp93]

So awesome of Nelson to let you in to his "laboratory". Also, I love the shot of Nelson at the end with a picture of Einstein over his shoulder. Nice work Mr. deMille. 😎🎥

[@opk157]

What a great character and loving his profession. It shows!

[@truebluemiata]

That picture of the first transistor ever made sent chills through me as I contemplated it. I wonder if the inventors realized the potential of what they had created?

[@jmchez]

When engineers, also from Bell Labs, patented a system for Light Amplification by the Stimulated Emission of Radiation, they were asked what good was it for and they said they could not think of any practical applications. Think of the endless uses we have today for Lasers.

[@jmn1234]

I love it! Audio genius, Nelson Pass, is using lamp-cord type speaker and interconnect cables! Excuse me while I take a victory lap.

[@Aswaguespack]

Thanks Steve for sharing with all of us this guided Video Tour of one of audio’s most innovative pioneers in this world of Audio excellence. What a treat to share a brief glimpse into the private domain of one of the leaders in the development of consumer sound reproduction! Thank again Steve. PS. I do miss seeing your shirt today 😂

@@salvadorrodenas3071 Fremer is at the forefront of this dishonesty.

[@salvadorrodenas3071]

@@basspig nobody has a gun pointing to his head to convince he/she? has to spend X money. I listen daily through cheap electronics with great results, however, I've also satiated my desire, some times, to own expensive, exclusive items I reckon now they weren't a necessity in order to listen music with high quality but, you must be aware that this hobby has many facets, as many as audiophiles. Look at Nelson, he adnowledges that with certain loudspeakers, one watt is all he needs but he has designed a built many thousand watts along his career. Is he dishonest with himself? I don't think so.

[@basspig]

@@salvadorrodenas3071 No, but the dishonesty of the snake oil audiophool business would be found in violation of Federal Trade Commission laws if anyone in the government were competent to evaluate audio gear. Such marketing quickly separates fools from their money. Building large and powerful amplifiers is not in that category. Sometimes the power is necessary to prevent clipping on unusual types of recordings, such as pyrotechnics.

Ive had the great pleasure of not only enjoying many of his designed products over the decades, and thoroughly enjoyed them all greatly! To say the hi end audio world wouldnt be the same without this man would be one of the great understatements!! A true legend, and master of his craft. SO GOD BLESS AND THANK YOU NELSON!!!

[@Technical_Audio]

Steve, thanks for this series of interviews. At one point I think you asked your audience for questions to ask Nelson. Maybe it’s too late and you’ve already taped the entire series with Nelson, but if not, here are a few questions I’d like to put to Nelson. What has been Nelson’s relationship with other notable amp designers? John Curl comes to mind foremost, being a contemporary and open-minded thought leader too. But also, Dan D’Agostino, Bascom King, Bob Cordell, Charlie Hansen (deceased), Jim Bongiorno (also deceased), etc? Does he get on the phone regularly with any of these guys to swap circuit tidbits or does professional competitiveness prevent that? Who among other amp designers has he learned from and respect the most? What are his thoughts on tube amps in general (not the peculiar Korg tube, but tubes in general)? What are his views on the technical advantages and disadvantages of tubes versus BJTs, JFETs and MOSFETs? I would challenge him on the wisdom of having Pass employees all use the same speaker, the Tannoy, for amp listening tests. As revealing as it might be he runs the risk of a house sound that is the complement to the peculiarities of the Tannoy’s sound. Wouldn’t it be better to also use a wide variety of speakers to test amps: multi-driver cone speakers with complex crossovers, ribbons, electrostatics, horns - all of them. What technical tests does Nelson use that he feels correlate well with listening tests? Finally, Auburn CA, where Pass Labs is located, is hours away from Sea Ranch, where Nelson lives. It seems that Desmond Harrington runs the place on a day-to-day basis, and that Wayne Coburn does much of the design. How involved is Nelson in his company these days and how often does he get to his factory? Thanks

[@ikecarumba9486]

Hi Paul Kerry here aka Vintage Audio Trader. Nice video. Hadn't known till now you have a pair of Imperials set up with Tannoys. You might remember my old web page, showing off my Imperials, they're great bass bins. Unfortunately I sold my Imperials and most of my vintage gear, I'm into dipole bass these days with field coil drivers on conical horns.
