has anybody compared the dac section of the gcha as compared to the ps audio digital link outboard dac? what are the differences, in terms of chips used and especially the sound quality?

sorry bump again

well, i just wanted to know is there anyone still have one of those and want to say something about this little beauty? from the search, this seems to be what i'm looking for. the only concern i still have is, if this can power my power hungry 600ohm dt880 and power it good?

it is as good or better than any amp priced likewise. it likes grados. it was a little dry with the k701's. if you are doing senns forget this and go rsa.

They have no trouble driving the 600ohm dt880.

thanks guys.

no senns, so far. i'm like cold, dry sound sometimes so maybe i'll get a k701 later if i can get a good deal for this

The GCHA is a wonderful refined amp, well worth its price. I may well buy one again sometime. I thought it was great with Senns as well as with the K701.

A further thought:

recstar24, who reviews for 6moons and has written a very good review of the PS Audio in that online journal, has described the GCHA as "soft and bland" on another forum.

I'd re-phrase that to "suave and refined." It all depends upon the sound that you prefer. I found the Zana Deux over-the-top with exaggerated sonics, for example; the GCHA is a great cure for that.

mm... how much are they going for right now?? Used... I mean..

Read in this thread that they do Grados very well.. would this include the HP-1000s?

What about the extremely power hungry K340? Will the CGHA drive these as well??

Not sure if this was discussed here yet, but the GCHA can now be had new for $500. Is this a steal at the end of a production run or a fair, lower price for  outdated tech?

 

I am curious as I shop for a starter amp to drive AKG 702's. This unit seems to be the most "substantial"  (as in well built, reliable and backed by a reputable brand) of options in this price range that has a usb dac onboard. For example, I am considering a dacport for its easy portability, but can't help thinking the GCHA would drive the AKG 702's with far greater ease.

There is little to the concept of outdated tech in head-fi, especially with amplifers and something that's only about 5 years old, we're ampliying headphone signals from power sources, nothing super high tech, we're still using similar circuits, opamps, power supplies ... It's more a matter of design and engineering than 'tech'. There's plenty of good designs from the same time as the GCHA, still popular, you can't really extrapolate sound from age or market position, I've heard it with the K701 and it's a serious desktop amp alright.

Thanks for the input. I appreciate it. I tend to agree about amplifier technology not being terribly complicated. In fact, even beyond "Head-fi" the amplifier is the component whose job is most straightforward in any system and therefore lasts the longest. As a general rule anyway. You see amps in systems for years, still going strong, whereas sources like CD players seem to warp toward obsolescence.

 

On the other hand, I should have been more specific in my question, because converting (and especially then upsampling), a USB signal from a cpu source is "high tech" and that is where one technology may eclipse another; i.e, the value of the GCHA has diminished because although it is still a solid HP amplifier, its USB DAC function is now surpassed by other designs. The GCHA released circa 2006, and there have been many advances in DAC technology, and especially USB DAC technology since. For example, even as a newb, I know that many advances have occurred in the area of jitter reduction alone, much less, clocking, upsampling, managing USB power noise and other hi-tehc stuff I am not smart enough to understand. 

 

I like the GCHA at 500 bucks even in light of the potential shortcomings of its aged USB dac, b/c you theoretically have 500 more bucks from its original retail to get a DAC if the need arises. 

 

Now I just need to get clearance to spend 500 bucks from the "boss" ....
