I am really interested in this pre amp. I have the GCC-100 (underwood mod) and it is the best solid state I have heard. However- I recently got my Atma-sphere MA1 OTL amps re tubed, and they seem to be outstanding (being fed directly from a GCPH phono- which is also gain cell)
The problem with the GCPH direct combo is there is not enough gain for me with a .5mv Sumiko Celebration (although a MC step up device may be the fix.)
And of course I can't plug in digital sources with this configuration, and would also like to replace it with a Tron Seven phono pre- which I had for in home audition. Tested only With the GCC- 100 amp, the Tron was better than the GCPH.
So this leads me to need a pre amp. I have ordered the new H-Cat remote pre, which will be here in a few weeks. I am thinking of also ordering a GCP-200 and GCPS to have here at the same time, and returning the lesser unit.
I really hate to Jerk around Audio companies by ordering something I am considering returning, but I think this would be an amazing shoot out.
As far as amps -I have the MA1's to test as well as the GCC100 - so I think I can really give both pre amps a fair evaluation with tube and SS. (and also bypass mode using the GCC-100 directly - as well as the GCPH/MA1 direct combo to test for any sonic signature in the pre's.)
However I do use Cerious cables, which supposedly take time to settle after being moved.
If I ended up keeping the PS Audio, I would probably get it modded by Parts connection, since my modded GCC-100 sound quite a bit better than stock. (one reason I'd hate to sell it- just in case the Atma's are too hot for summer, blow tubes, etc) I can also use the GCC-100 just to pre-power my powered subs - and drive at speaker level with the ability to tweek bass levels via remote!!!! That would be cool - the OTL's on top and GCC100 on bottow- but then the system gets so complicated- I also just ordered Zero's for the Atma's so with this much gear - things could get complicated very quickly in a small apartment.
Maybe the bi- amp thing will have to be set aside and sell the GCC.
I'll post back though on the H-Cat and possibly the GCP-200.
Man this hobby is complicated - I can't wait to just settle on my latest electronics and from end and stop swapping components for a few years.
