Today I talk about the AGD DUET MONOBLOCK amplifiers. These two boxes are small, lightweight, run cool and have effortless power to drive any speaker. These use GaN MOSFET tech and these are created my Albert Guerra at AGD. These are the newest amps from the AGD brand and they stole my heart indeed, as well as my bank account. There was no way, no way I could go back to any other power amps after hearing and experiencing these..
Enjoy!

Oh and to the person who complained about the fact that I was wearing my PJ pants, YES SIR I WAS! See, I believe we should be as happy as we can in life and I live without negativity, anger, hate, etc. I live to be comfortable and happy, noting more nothing less. Hell yes I wear PJ's on most days, after my shower. Why? My wife an I live very remote and are home 98% of the time. Why on earth would I wear dress pants to unbox an amp in my own listening room. I'm just a guy, not a business man. I'm like you guys, a crazy audio nut. Maybe I will do my next video in my full PJ's ; )

Great review! I purchased my AGD tempo 3 years ago when it was first released. Very, very clean sound, not sterile or analytical.

The tempo is also gorgeous and a great way to get into AGD. I haven't heard it but I have spoken to a couple who have and they love it as well.

Is the lumin U2 close to the Hifi Rose 130?

@@Gonzinatra on sound it has some similar qualities. Both bring a solidity in the bass. The Rose does the spatial thing a little better imo. Both are great choices and can’t go wrong with either.

I have the Audions. Mine were manhandled by customs inspection so I had to polish them. They polished up just fine using a small mechanical polisher and Flitz metal polish.

[@peterw2714]

How did the AGD sound compared to the Axxess Forte amplifier with the X2’s?

[@HiFiHuff]

I much prefer the AGD. As stated, the Forte 1 sounds amazing with the X2 as they were made for each other. The Forte though, doesn't create that same magic with other speakers. Bass output is lower than most I have heard so tuned for the X line I think. The Forte will be more mechanical, more analytical and punchy/fast. The AGD's bring a little romance, warmth and bring forth more resolution. It's a beautiful sound. The Forte 1 is a more aggressive sound, making. these sort of Chameleon like. I mean, they sound VERY different with the Forte vs the AGD. Personal tastes will vary but if you like hyper detail with less bass down below that's what the Forte will do here. I find the X2's with AGD to be sublime so that's my pref with the X2. I also prefer the AGD with the OGY/BOB (my fave speakers) vs any other amp as it fills out the mids and brings so much life. In any case, these are solid amps if within ones budget. Thank you for watching.

[@anukrw]

What a great review as always. Mate I would love to hear your thoughts on the AGD Solo. Is it twice the amp.. Keep up the gear work.

What DAC were you using for theses auditions ? thank you for all your work.

[@HiFiHuff]

I was using the DAC inside of the Alto II preamp which is a custom made R2R DAC by AGD and it's AWESOME. It's the second time now I heard an internal DAC sound as good as a $10k box. I have a couple;le of DAC here that I really like but with this setup, they are not needed. The phono stage inside is also remarkable, MM and MC. I will do a video in a month or two on the Alto II. Thank you.

How does Prima Luna compare, sound wise?

[@edvanwinkle4112]

Was your review and comments based on using them with your Puritan 156? In other words, were they plugged directly into the 156?

[@HiFiHuff]

Actually, it has been out for the last two weeks as I am waiting on the larger version that I ordered. So here, was plugged into a generic power strip. I did have my electrical redone here at home as well with a whole new ground added/redone. But I do have the larger puritan coming, love that thing.

[@edvanwinkle4112]

Don’t know if you have an opinion on this but enough people seem to think that amps in particular shouldn’t go into power conditioners. Curious to know your feelings on any of the amplifiers you have used. Would you unequivocally recommend amps going into the Puritan?

[@deanbrandon3615]

It helps when you not only describe the sound, but compare to other amps/systems, especially known more common systems. In this case, I would want to know how the separation compares to say, Hegal, who is knows for stage separation and bass control.

[@HiFiHuff]

@@deanbrandon3615 Ive heard many hegel amps, two were here for a week or so. As stated, I’ve never heard fiber amplification than these AGD amps. For me, personally, they have made other amps obsolete. I am blown away by them day after day and with each day I adore them more. Hegel makes fantastic amplifiers but they are bigger, heavier, and sound quite different. These do detail and separation better than any I’ve ever heard but also have a splash of body and warmth that is as good as it gets for my ears. With all that said, the duets and alto II loaded with the DAC is a close to $20k purchase. So, it better dang well be pretty special. :)

[@deanbrandon3615]

Any advice on speaker pairing with the AGD Duets? I have Bowers & Wilkins, but not sure if they would pair well….

[@deanbrandon3615]

I just received a set of AGD Duets and the Alto Preamp two days ago. Too early yet to comment on the sound, but suffice it to say, I am very happy. Paring these with my preexisting Bowers & Wilkins 705S and a 10inch sub seems to work well. I just wonder how these AGDs would sound with different speakers. I’ve got so much $ in them I want them to shine (not literally - as I got the black finish).

It great to see AGD making a name for themself, and making Class D an Audio product worth buying at long last.

There is a very high pride of ownership with the AGD products. From the artistic beauty, to the custom tech made just for them to the way they are shipped and packed. The power cords and of course, the sound..all make for an experience that is rare unless you step up to the $50k and up range.

I always liked sound of these amps but not convinced with price of amp and pre amp combo. I rather go with Yamaha m5000 and c5000. I wish you would have done side by side comparisons in room with different amps for better understanding of sound

[@HiFiHuff]

People HATE when I do sound demos for some reason. I heard the Yamaha m5000 and c5000. Very nice and in the same price bracket. I'd still tale the AGD (and did) due to all of the reasons I mentioned. Small, no noise, no heat, upgradeable by the owner and the sound, which is #1 for me. Never heard amps like this and the build and parts quality is up there with some much more pricey products. The Yamaha is gorgeous though, just as many are. Audio is very personal and I always tell people to go with what moves them, not what moves me ; )

I wonder how it would compare with the Jeff Roland Model 125, also a work of art in its own right at a fraction of the cost. Would the differences be that great?

[@HiFiHuff]

These use modules, made by Alberto, for audio only. I'm sure the 125 will sound lovely but it's not a monoblock amp, stereo. It's also not GaN based from what I understand (I could be wrong). Alberta makes his Tempo stereo amp which would be more comparable to the Rowland though the Tempo uses Albertos design and GaN module. I love that more coma its are making amps like this and see many more doing it over the next few years. We will see way less Class A being made IMO (Luxman already stopped according to rumors). Thanks!

@@HiFiHuff Thanks for answering. Enjoy the videos even if I will never own most of the stuff...and that's alright. If I do make a play, I am interested in the Closer Ogy and wonder what SS amp might bring it to what its capable of.

I wonder how grand vivace compares with duet. i like the tube aesthetic.

[@HiFiHuff]

From what I hear (from those who have heard all of the AGD amps) is as you climb up you get more of what is there. Kind of like from Audion to Duet. I bet the Vivace is very nice but probably 2-3% more of the good stuff. Maybe one day I will get to hear them.

[@Albert-nj9xm]

The GV and DUET share identical power stages (components, circuitry, only a different physical implementation). The only difference is the power supply which is bigger in the GV (we had more space obviously). Sound wise they are very similar, with the GV having ~20 to 25% more power so probably more headroom.

Yea, they are expensive for sure though there are much more expensive pieces out there that may not even sound as good. I wish stuff like this wasn't so expensive. I get it though, as these are made in small quantities I am sure, by a. very small company. Custom enclosures, custom modules, engineering...has to cost Alberto a lot to have come up with his products and I am sure he sells very little compared to say a Yamaha. Thank you. Also, who knows, maybe one day you will see a used set of AHD amps for a steal. The Tempo is their stereo amp that uses the same tech and is half the cost.

Comparing the Ganfet technology in the Hifi Rose, what are AGD doing differently that makes all the difference?

The AGD amps, unlike many Class D amps use custom made modules. These were created by Alberto and his team just for audio. Many class D amps use chips from power supplies. They do not sound nearly as good. The Duets also use this tech with the power supply, which really improves them vs even the Audion. These have a quality on a different level from the Rose amps, they just do, With that said, they may sound different with various preamps. The Pass XP10 I tested them with did very well though. Lovely. The Alto II is a perfect mate, so I chose it for the amps. Thank you.

@@TriAmpMyFi That is a different matter all together. Musicians "make" and create music. HiFi has absolutely nothing to do with music.

[@9XThunder]

Except audio note, that the only hifi that makes music !!!

[@TriAmpMyFi]

@@PetraKann . Hifi is the playback of musicians' making and creating music via recordings.

[@HiFiHuff]

Sure they do, they amplify the signal to bring that signal to the speakers which in turn make music. Cant have music without some type of amplifier to amplify it. All amps sound different, period, I never heard two amps that sound the same, ever. Thanks.

Using gloves for an unboxing is a bit much!

[@danmarjenka6361]

Maybe because they cost $12,000.

[@HiFiHuff]

Not when handling these as they will grab any fingerprint of scuff. They come with the gloves for a reason and since I was filming, why would I want them full of prints? Exactly.

[@HiFiHuff]

@@danmarjenka6361 No, it's because of the obvious reason, they are polished and collect fingerings like mad. Was filming them, didn't want them all smudged up. Why would I? So no, wasn't much at all. : )

[@danmarjenka6361]

@@HiFiHuff I completely understand where you are coming from. I have handled lesser equipment with gloves because I just like my gear to be flawless.

I can't hear you over all the ultrasonic noise.
