AMB Gamma2 DAC sound impressions? - Page 9

post #121 of 185

Suppose I should continue saving for a Gamma2 then. Would loooove to hear one with my M^3 and DT880 600ohm  Can't bring myself to sell my HF-2 to fund the Gamma2 though. Beginning to love them again  Looks like I would have to get it built by MisterX. Buying new is always expensive, though  I love buying used. Bought my M^3 used (currently have AD8065 in L and R channels and OPA627 in Ground) with a huge 24V power pack for the equiv of $200us

Thankfully I don't need a balanced system yet so the γ2 will stick with me for the unforeseeable future. I even built my β22 single-ended!

I'm not serious about buying right now, so I thought I should just ask here. I was also considering building it myself.

 Shahrose, can you also compare the Buffalo to the y2 more in-depth? Also, does the $400 include the power supply?

EDIT: I want to clarify that the $400 was in CAD currency at the time. The price I paid in USD was less. You should PM MisterX for the exact quote, which may or may not have changed. It came with the switching power supply too for that price.

 

The Buffalo is a bit more detailed in the treble and is far more unforgiving of recordings. Bad recordings sound terrible, while good ones sound amazing. The y2 makes almost everything sound good, though not always amazing.

Initial impressions also indicate that the Buffalo has a more airy/holographic soundstage. I think the y2 is smoother and somewhat warmer (perhaps a tiny bit bassier too), which may explain why it's more forgiving of recordings.

A little OT, but I've owned all those opamps plus more. Over the 30+ comparisons I did during the period I owned the Rockhopper M^3/Sigma-11, I consistently found 3xAD8610 to be the best (fastest, most transparent and neutral). They are also the ones Ti (AMB) recommends. Recently, someone I know who owns a Beta22 swapped the opamps in his M^3 with the AD8610 and he says the gap between the M^3 and Beta lessened considerably.

post #126 of 185

Don't want to derail this discussion, but thank you! I suppose I should try and find 3 AD8610. Any links? I had a look on ebay but want to be 100% sure I am getting the correct ones. Maybe PM me links? Cheers.

Btw, those 6 opamps came with the M^3 (OPA627 and AD8065). Come to think of it, I paid an extremely good price for the M^3 then.

 

BTtw, you say the Gamma2 is bassier than smoother than the Buffalo, that sounded great to me. I don't like bass heavy 'phones, but I think they could all use a tiny bit more bass than they currently have and be smoother sounding. Gamma2 is sounding like a better and better DAC to buy each day. At times though, I even find my K1000 bass light too bass heavy. Same goes my DT880 600ohm.

Actually, I think the y2 is warmer more than than bassier relative to the Buffalo.  Its smoother and warmer nature allows you to turn up the volume more and it gives you more bass.

 

I like the lower midrange warmth of the y2 that the Buffalo doesn't have. Where the Buffalo's strengths lie are in its sense of space/soundstage and its more detailed/extended highs (both a bit better than the y2). After spending some time comparing, I think these DACs aren't far apart in quality, but are voiced differently. If I were to choose between the two for SQ though, I'd take the Buffalo. Aside from the differences I mentioned, it seems to have a subtle edge in clarity throughout the frequency range.

FWIW, I'm working on getting one via Marshall and he's asking $330 for the DAC only, shipping is extra.

 

Cool impressions everybody, I can't wait to hear the γ2.

post #129 of 185

Wow. I didn't know it could be had for that cheap. Then again with shipping to Aus and a power pack, probably looking at $400 anyway.

post #130 of 185

Having spent a few days with the γ2, I'm very impressed with this little box.

 

The overall presentation is lovely. It's very balanced, midrange is awesome and the details are there too. It's hard to put it into words, but when I play stuff through this device, it sounds more like music.

 

This is using USB for power and input. While I'm not in a hurry to get a proper power supply and feed it through S/PDIF, I'm very excited after reading about Shahrose's findings when he went from USB to coax.

Depends on the S/PDIF transport though. The USB implementation of the y2 isn't bad at all. But, if you use a sufficiently high-end transport to feed a coaxial signal into the y2, it will sound noticeably better than USB.
 

post #132 of 185

Yes, I plan on getting a HiFace or a similar device.
 

Have you tried USB vs. coax when the γ2 is powered by USB? Eventually I will upgrade both but I'm wondering should I go for the power supply or the transport first.

I think the regulated PSU makes a small difference to the SQ (mainly in the bass). I haven't made sure if it's real or placebo, because I haven't done any rigorous tests yet.

post #134 of 185

I switched to coax and I'm happy to report my initial findings match yours. Significant improvement in soundstaging and high end detail. The sound is more refined all around too.

 

My current transport is Essence STX with some generic freebie cable that isn't probably up to standards.

 

Time to sleep on it and continue testing tomorrow.
