Anyone? Any updates? Anything?
Intrigued by this as it looks like a reasonably compact way to build a balanced amp with enough power (in theory) for something like the HE-6s. I sent a couple questions to Craig at EC. Won't be a cheap build (not when compared to the cost of something like an Emotive X-100) as the OPA541s are about $20 a pop. Although the build will be cheaper than a balanced B22.
Plenty of other chips out there that are better in most aspects and cheaper too. Just build a 4 channel gainclone and call it a day. If you want to use a SE input, want it to be cheap and don't care about the quality you can wire up some simple DRV134 stage to do that.
I very much appreciate, desire, and will pay for high quality, but I am also a cheapskate. This is a very tough hobby for me to be in because of that :)
I'll focus on finishing my B22 for now. I also have project ADD.
Still tempted, but looks like it will be $300 before casework if you need the input transformers. $200 without them. Then again, this is similar to a $3500 amp. Then again, that $3500 amp gets ridiculed by many.
May I ask what $3500 amp? lol
