Hi Guys, this amp is so much better sounding than some mass produced designs. This amp is very similar sounding to our $3900 desktop amp the Prautes. The Prautes is a step up for sure and sounds as good as ANY amp. The Sustain84 is not quite on the level of a hand made point to point amp, but I wouldn't sell it if it didn't just straight outperform. The look is similar to the big iron as well, with removable tube shields and roll-able tubes. The design is straight forward and purely for headphones, so it won't start to annoy you with a lot of unnecessary bling.
If you ever have an issue or a question, you don't get some faceless twitter account, you get the owner on the phone, I do all customer service. If you aren't happy, I'm not happy.

I own the Prautes and can vouch for its excellent sound. The owner is indeed responsive (he actually answered the phone when I called the first time, and returned my next call with an apology for the few minute delay - no annoying phone tag) and he is passionate and committed to his products. I spoke with the owner several times on the phone and by email and experienced extraordinary, personalized, and concerned customer service.

Hmm, $899 lowest drop price (25% off) is decent but the overall price puts it into a crowded/competitve market. No extra inputs or output (is it that costly to add a stereo mini?) gives it a bare bones vibe and relatively low power makes it a tougher sell; any HE6/HE1000 fans out there(?). Also, the use of a relatively obscure tube, not EL84, but ECL84 does not help.
Cypher does have a sound or lack thereof that I find appealing: clear and transparent. At least with their Iem (which I have) and the Theorem which I've heard. Don't know if the Sustain84 has this sound, but at $900 it is a bit of a risk as I would probably would take a hit on resale if it does not have "that" sound. Having said the above, and based on the two reviews that I've read (HP Guru and Toneaudio) I think it might be a good match with Grados.

This stuff is really expensive for what it is, it even doesn't have custom wound transformers for goats sake!
