Thanks Robin,I'm totally stoked to get the 2.5. I think I'll eventually get the custom z-sleeve for it, and the ERS material as well. For now I'm just incredibly excited to hear what it can do in my system.
Quote from: satfrat on 21 Nov 2008, 01:18 am Tyson (or Mike), do you feel that further tweaking of the bias will be needed as you gain some hours on this system or is fluctuation on nonissue? Just curious.Robin, I think it will be pretty stable. They used 15 turn pots, so I was able to set it very precisely but things do change over time and it will drift but I suspect that will not occur for a while, at least I hope so as those amps are pretty awful to move around.

No, we ain't. You should see the bruise on my arm from moving my cabinet around. Since the cabinet is too narrow to load anything form the front, I have to move the whole thing away from the wall before I remove any gear from it. It's HEAVY with the audio-gd equipment. I look like a junkie that missed a vein and bled out internally, seriously. Of course being on plavix from my heart attack 2 years ago doesn't help....
Nice review, Tyson!These products seems very interesting.I have some questions.How hot does your amplifier run? The radiators do not seem very big on the images.And you're not worried about how long the composants inside will last, which such a power in class A?Still happy after a few months?Do you turn it off at night? If so, how long would you say does it take for the amplifier to reach its full potential when turned on?And have you compared it to other amps? Likewise, have you compared the Dac8 to others?
It is rare to meet a true audiophile also a pro audio engineer.
My system is actively bi-amplified so this involved resetting the gain settings in my crossover (modified DCX2496) to match the Audio-GD to my other amp. We ran these on the top end with the little Rotel 1080 on the woofers. While it sounded good it wasn't what I thought it should be. We then configured the system with both Audio-GD amps so they were feeding both the low and high sections of the speakers. To do this we had to remove the C1 (I think) module so we only had 6dB of gain from the amps thus limiting our volume but the resulting sound was exceptional. Both of us were pretty stunned, particularly on the bass.
Why did you have to remove the C1 module (I presume that you are referring to the pre-drive amp component, to use a term from the GD-Audio website) as I thought the C-1SE was designed to support bi-amping? Does it conflict with the Behringer in some way? I would have thought you would feed the signal from the pre-amp to the Behringer to the pre-drive amp component to the output drive amp.Lastly, were you bi-amping the Geddes speakers?
