You certainly put together an extremely clean build Mazuki. Nice job.
Thanks Ech0

Sort of an out-there question, but how would the Opus compare to something like the KECES 151? Are they available as pre-built units, or would one purchase the components and have someone DIY it?

It's almost a joke comparing a WM8040/WM8041 DAC to a PCM270x-based solution. The OPUS will win by a huge margin, like HUGE.

They're available as built and tested modules, you wire them and do casework.

Skylab: Nice review, thanks.

Interesting. Are there any companies or members who do the wiring and case stuff? I've never touched a soldering iron before, and I'd be afraid to make my noob mistakes on something other than junk parts.

Now I wonder how an Opus would sound with a DV336....hm....

Excellent write up, Skylab. I've been enamored with the B22 for quite some time, and the Opus is a very interesting piece of hardware that I'll have to look at more closely.

I was hoping someone else would ask, Mike, but did you adhere strictly to the AMB specs, or did you change a few things?

FallenAngel, when can we expect your take on the Beta?

Exactly as AMB intended. The power supply transformer is 100VA though.

Nice write up. I'm building a b22 so i can't wait to hear how i compares to my John Broskie valve amp, graham slee solo ampand my modded x-can v3. I'm also getting an opus dac so i can compare it to my beresford dac and zero dac. I should have an interesting write up to follow the build.

I would also expect the opus to sound better than your dennon's dac. I can't wait to hear how it compares to the beresford. The beresford is great for it's price range!

Thanks Skylab for another great review I know this is very late post I just found this review, I’m curious to know what config the B22 was either 2 or 3 board? The links in Ech0’s post 13 are dead, so I can’t see.

It’s interesting how people perceive sound differently, I’ve replaced my DV 337 for a AMB balanced M^3 (B22’s little brother). The M^3 for me was in whole different league, although the bass is not as big as the 337, which I now feel maybe on the heavy side of neutral. Just throwing this out there, but maybe the Senn HD6** might be a better choice of phones for the B22. I know your not a Senns man But for me, armed with my 650’s the choice for me would definitely be the AMB M^3 over the 337.

Thanks for the impressions. I am have Maxed out Supra SDS and two B22 with a GS-X amp. I thoroughly enjoy both of my B22s. I agree that they do the midrange quite well too. I'm glad you got to hear one

I am really not sure about the # of boards. If it wasn't clear, this B22 was a loaner, not mine personally. So while you may be right that Senns may be a better choice for a B22, that isn't really relevant for me personally. I have owned HD600's and 650's before and don't really care for them. But the B22 was "just passing through" anyway

Oy! Where can i start looking for an unbalanced b22 -set to buy, since I'm not a DIY guy myself.. Should i just contact some of the guys who generally make them? Might be tempted in the near future..
That integrated opus-dac sounds good too.. Hmm..

Great review, i must say, though afterwards

So, is the B22 the best solid state amp you have ever heard?
