Hello,
first post, long time reader, please don't be harsh with me, I read the forum rules a couple of times.
I have Stax SR-2170 system for two years, very happy with it.
However, I received an Audeze LCD-2 as christmas present (god bless christmas!), but...I don't have a proper amp for them.
I thought this is a great opportunity to start my first DIY project (this transconductance amplifier).
But, I have a few (probably dumb) doubts about the design.
Kevin said there's no way to make a balanced/bridged transconductance amp, but looking at some commercially available products, I've found this:
Bakoon AMP-51R speaker amp: ("Maximum power output: 100 watts in stereo, 250 watts in mono")
http://www.bakoon.com/product/amp-51r/
Audio GD NFB-1 headphone amp (fully balanced, class A, with 4 pin xlr headphone output)
http://audio-gd.com/Pro/Headphoneamp/NFB1AMP/NFB1AMPEN.htm
I mean, is something wrong with those transconductance amplifiers or a design of this headphone amp with a 4 pin XLR output for the headphones can be done?
Thanks for your attention, and please forgive my ignorance.
