The most dynamic Tube amp in the world? 🤔Cayin CS150 Tube integrated amp review.

[@MusicLover-01]

Any KT above KT66 tends to go in a boring (slightly dry) direction for me personally, however this KT150 in triode mode grabbed me, very pleasant sound and exciting to think of the harder to drive speakers it opens up to tubes. Triode sound slows things down a touch and allows you to be drawn into the magic, very impressive.

Great review. Thanks Thomas. I call the Cayin CS150 and the Concept 500s my own and couldn‘t be happier-it‘s a great combination. But I upgraded the capacitors in the preamp stage of the Cayin and replaced them with Jupiters which further improved the mid-bass of this combination, adding even more punch and realism.

[@ThomasAndStereo]

That is so awesome. As I mentioned in the video, I wish bass could be a bitter 'fatter' and you solved the problem.

[@christophe2691]

thank you Thomas for this video, very fair, concerning the Cayin CS150A amplifier, what I can say is that this new amplifier was quite lively in the medium / high frequencies, sorry for my language, because I am French, but after several weeks of wear of the electronic tubes, the sound is excellent in the medium / high register, almost perfect, a great dynamic, the 6NS7 Tung Sol tubes of the preamplification stage need some time to set the tone. better. this is arguably my best amplifier. however, there is also a Cayin preamplifier, the SC 6LS MK2. a marvel to discover, exceptional quality, coupled with a professional Yamaha PX8 power unit on Cabasse Clipper M1, it's woaw ... the components of the preamp SC6lsmk2 are of quality, resistors takman, nichicon, real cap etc etc etc magnificent! the sound, transparent, detailed, deep, dynamic. :)

[@ScottGrammer]

Tube amps tend to sound more powerful than similarly-rated solid-state amps because the clipping characteristics of most tube amps are less harsh. This is not always the case, though. I have heard some vintage solid-state amps (typically Marantzes) that can visibly clip on an oscilloscope while still sounding amazingly clean. It's really surprising when that happens.

[@carlosoliveira-rc2xt]

Not necessarily true. Classé DR3 for instance sounds like a hundred watt amp and when it clips you hear it easily. There are other factors at hand and the one you mention is overstated.

I have the Line Magnetic LM-150ia and I use the Cv181 psvane instead of the stock 6sn7. The preamp tubes are psvane 12ax7. It’s a lot like how you describe. Tube Pre with SS power. Not bright at all. Huge sound stage and the tube holographic! They have better control of my Elac Adantes than any other solid state amp I have tried. Billie Jean is a track that I have been using for auditions for a long time. It’s handy back in the day when dealers only had CDs and MJ was a common artist. One more interesting thing about Billie Jean is that in a very good system, you will be able to clearly notice and count how many times he snaps his finger through our the song. Do try and share.

Thanks Thomas for your review. The KT family is the sound I want. I hope you will review the KT-170 soon.

[@martinda7446]

It is just that a tube under the right circumstance is capable of massive dynamic range. A small double triode used in a microphone front end for example will out perform any device simply because of it's intrinsic properties, swinging much higher voltages along with its high impedance etc. 140db dynamic range is easily within reach and was indeed part of reason why those valve mikes were so extraordinary and did measure this well. Output stages have a much harder time reaching anything like that range, and of course they can't - with limitations coming from earlier in the circuit raising hum and noise and power limitations..I guess if you were really careful....but you would always be 40db 'ish' behind a small signal device considering the same care taken there. I have never heard a solid state preamp worth using. (Full stop) The SP8 was my favourite for many years, and the next best thing was no preamp at all...Though it didn't help my record player doing that. On a different note.. Did anyone out there ever try the Aurex electret condenser cartridge? It came with a little energiser/ phonostage amplifier and was amazing but there seems to be nobody else remembering it. Being a Toshiba it made me start looking and I found something I had not seen since the Philco magic light of the 40s. The Toshiba C-100 photoelectric cartridge..I would love to talk to those Toshiba Aurex engineers, they were crazy! The C-100 has serious promise. Edit: Even if it did have a pair of photo transistors..I doubt you could accommodate a pair of photo tubes...

( Sonus Faber was my choice, Sonetto V ) The seller told me that these Klipsh work very well with only one thing : tubes ! and that with that kind of amp, you'll have chills ! Nothing to do with a transistor amp And he was right ! One of the best experience of my life. About half an hour, we change the speakers for Sonetto V, wich are supposed to be very good speakers. And what ??? it was sooooo flat, so close, good speakers but no emotionnal. nothing. Particulary on Alive And Kicking, live version, by Simple Minds. The drumm, the voice of the female at the end, with Klipsh we were at the concert. The combo RF7 with Cayin is amazing. I will buy this and nothing else.

You should listen the Cayin Soul 170i or the Galion TS120SE one day if you were impressed with the CS150. RF7 yes, it has a more lively and color sound and I bet the Sonetto has a more neutral sound.

@@ThomasAndStereo Due to the different distortion profile as the amp approaches its max power, tube amps can be driven harder before distortion becomes subjectively annoying.

Frankie, I do want to say, when you go audition the Cayin, make sure you also audition the CS100, the difference is the CS100 sounds more like a tube amp where the notes seem to linger a bit longer. It is more airy and less 'dry' on the top end. Bass and dynamics might not be as good as the CS150 but with the Concept 500, the CS100 sounds really good especially if you are chasing more after the tube sound.

[@saint6563]

Watts are Watts. Damping Factor can play a large roll in perception of quality as well. Current is what makes the difference in power between valve & solid state amps of the same wattage. The 100 watt amp w/the higher current output will sound more powerful than the 100 watt amp w/the lower current output.

[@razisn]

For two amps at the same power if one produces higher current then it will produce lower voltage I.e. loudness at the speaker end. You can’t have your cake and eat it too..

[@razisn]

And, btw, tubes are good voltage amplification devices but lousy current amplification devices relative to solid state. Hence all the trend with tube input and driver stages driving solid state back ends in hybrid amps.

Great video, Thomas! You gotta try the line Magnetic LM805IA integrated. 48wpc SET amp!!

[@ThomasAndStereo]

Thanks for the tip!

[@Nonsombun]

Thank you for this quick and clear answer. I hope you don't find it too inquisitve when I tell you I can buy the 150 for exactly the same price as the Doge 10 in my country and renew my question, because I understand that the price tag plays an important role and double the price in Canada can certainly not outweigh the highlight in only one respect (dynamics).

[@ThomasAndStereo]

Yes outside north america, you can get Cayin for cheap. we have a proper distributor support system so it is more expensive over here.

[@jastrel]

Hi Thomas, I am here again after 5 months…. I ´ve bought this Cayin and ti sounds Wonderful!! I will upgrade in speakers but I am considering the klh model 5 instead of the cornwall as i mentioned in my previous coment. I ´d LOVE to get your opinion or suggestion. Cheers from Spain and Happy New Year

[@billfarrell4387]

Hi Thomas Please keep reviewing the obscure products so so good always like your take btw the Carver Crimson 275 uses 4 KT 120’s rated at 70 watts per channel but more like 90

[@ThomasAndStereo]

Thanks, I will try to introduce unknown stuff as much as I can.

[@gryphongryph]

Love your channel, looks like great amps, do you get the Ming-Da amps in Canada? Would like to hear your view on the Cavatina mono blocks.

[@ThomasAndStereo]

Thanks, I did try a pair of Ming Da monoblocs at one point. I never shop for a Ming Da so I don't know. Cavatina mono blocks? Let me check them out.

[@johncoates4645]

Thomas another well thought out review, but please turn your tv off it’s very distracting and adds nothing to the review

[@ThomasAndStereo]

Thanks. Its also to mask the reflection on the studio light I use. Else the reflection will be more distracting than what is on the tv. I can give it a try and will use different camera angles to get around that problem.

[@mikewheeler3994]

Thomas, what speakers and turn table to go with this. Have $5/6k for speakers and $2k for turn table. Any recommendations from anybody who has a educated opinion is welcome to chime in.

[@CoastalEscapes777]

Thomas, thanks for another great Cayin amp review. Any preamp tube recommendations for the Cayin C55A to reduce some of the brightness on top end?

[@ThomasAndStereo]

We used some Telefunken and Mullard NOS and 6550 SEC cwing. I didn't get a chance to try Russian Harmonia tubes but I was told it is less bright by Mr Kanta.

[@fredflintstone8048]

KT150s are serious tubes. 70watts plate dissipation. Push pull configuration (class AB) tends to produce brighter highs and of course much more power than a class A. It would be interesting to listen to a single ended (class A) amp built with KT150s. Not as efficient use of power, nor as high a wattage (70 watts max), but my guess would be a warmer sound.

[@johnh539]

Kevin Deal said that he uses KT150 in his home Prima Luna EVO100 despite the fact that they are not one of the recommended valves for that integrated amp. I have not yet tried any KT valves. As I am planning on doing so, which would you recommend trying first. My system is capable of more than enough base so it is the top end I am trying to investigate.

[@tbear2327]

Hi Thomas. Great video as usual. I love your "stories" - they are very entertaining. When is "Mr. Kanta" going to to review this amp? I own the R8 which I have owned for a year. I'm running it with a Naim ND5 NX 2 streamer/DAC, Rega Planar 6 with Nagaoka MP500, Shiit Mani, and the Q Acoustic Concept 500's. I found the stock valves to be total crap and am now running two quite different combinations of valves, including Sophia Electric KT88-ST and 6SN7-ST, PsVane 6SN7-ST for the power supply, and Shuguang 6SL7-ST as one set, while the other set are NOS Mullard 6CA7, Sylvania 6SN7GTA, and MELZ military spec 6SL7's. I also have Svetlana 6550's and all combinations give a fabulous sound - each set sounding slightly different from one another. So, honestly Thomas, just how good is this Cayin CS 150A? I must admit that I am tempted to buy it as I have my main listening room and a totally separate lounge room. Either way, the better amp would go into my main listening room while the other would go into the lounge. Speakers? I'd probably buy the Spacial Sapphires or X5 OB as a second set of speakers to go into my main listening room. I'm undecided at the moment on other brands/models of other equipment that I would need for my main listening room. Perhaps the Auralic Altair G1 or one of the other great DAC's which you have recommended.

[@ThomasAndStereo]

Well, Mr Kanta will get it in 2 days. Mr Jazz just tried it and was impressed. I will perhaps post a follow up one day on my community page.

[@jfbaquero]

Once again a very nice review Thomas. The CS-150A is an amazing beast. I can say it matches and it's possibly better than my Audio Research GSi75 that also uses KT150 tubes (75 watts), the CAYIN is a fraction of the cost of the ARC. The CAYIN has a plus of being a full tube amp, it has tube rectification, UL and TR option, NFB control... did you try it? I use it with DALI RUBICON 6 and don't find it a bit bright with the stock tubes. DALI is designed for neutrality, never heard the Q acoustics. I am now testing the LINE MAGNETIC LM-805 that is a SET 48 watts class A, it's a totally different animal, but it's also amazing on a different level, SET has a kind of magic that's is impossible to replicate on other typologies. Both brands, are amazing.

[@ThomasAndStereo]

Oh wow, this is very interesting. I was thinking to get the Gsi75 at one point and to know the Cayin CS150 can compete is mind boggling.

[@jfbaquero]

@@ThomasAndStereo The only thing I would miss from the ARC is the tube hours counter, that's great.

[@gordonschafer8357]

Great review Thomas! You showed a Pathos integrated during, Have you done a review on it?

[@ThomasAndStereo]

Not yet. Maybe later.

[@chuckisidro8624]

Great content on your channel, Thomas! Maybe you can also review tube amps from Audio Hungary, like the A50i. We would like to see your thoughts on these and how they compare to the Cayin and Willsenton tube amps. Thanks 🙏

[@ThomasAndStereo]

Yeah, it would be nice if they reach out to me.
