Is there any news on if there is going to be a new run of boards available?

I'd be up for one and there seems to be a few guys earlier in the thread showing interest. How many boards/requests would be needed to make a next run feasible?

Is there anyone interested in doing a commissioned build of one of these when the boards become available?

PM Sent.

Three power supplies up. Load tested with Larry's Hybrid amp board - it's up with stable offsets hovering around 0V.

Maybe get it to make some sounds tomorrow eve...

I haven't been around here as much as I'd like lately, but wanted to say thanks for the gorgeous boards and chips! Hopefully, I can find the time to order the parts this weekend and I've got a spare Par-Metal case to put it in. With a little luck, I can stuff the boards between Christmas and New Year's and get it up and running.

I'm really looking forward to it. n3rdling's solid state version sounded incredible at the Orange County meet, so I'm looking forward to jacking my O2 into my own.

Thanks again!

Sounds exciting!

BTW, we'll get to compare the eXStatA to the Woo WES now...

Same here.

Did any compare the SE and balanced inputs? Is there any difference in sound?

Unless the source has a different output stage for its SE vs. balanced output I would think that if you were using short IC's it'd be impossible to distinguish between the two.

Be careful Nate! You'll get the peasants with the pitchforks after you!

I ain't skeeeered, I'll just start throwing transformers and chokes at them!

Balanced vs. Un - that's another thread isn't it? That said - we did notice a difference with the proto at RMAF. even though there's not supposed to be a gain difference between the two inputs, we heard lower gain on the SE.

Larry, did we ever listen to the dif's after we solved the source problem? I think it was only running balanced from my Opus the rest of the show.

Sherwood has listened extensively SE, perhaps he could be cajoled into sharing his experience.

I can A/B with my DAC Magic, but can't be sure of it's output stage topology differences between SE and Balanced.

The isn't any difference in gain between the inputs (or rather grounding one half of the input to be more precise) but balanced has twice as much voltage as SE (2V vs. 4VRMS) so the end voltage swing is doubled.

Slight clarification, feeding the amp with a balanced input provides the potential for more output voltage swing. But as previously explained by jcx this amp has sufficient gain such that even a 2V input signal will allow for maximum output voltage swing as limited by the power supply. I think I have that right.

 

[spritzer]

Indeed that is correct.

Feed it 4V and it should then output 2kV but that won't happen.

At a gain of 1000 it would try and output 4kV, wouldn't it?
