Well... that was a fast update. This is really great news. Makes me think about ditching headphone amps all together and being exclusively speaker amps to drive headphones. The speaker amp market is very competitive and the quality of the units is really amazing. Headphone amps aren't nearly as competitive overall.
This is why I started hunting down a speaker amp to basically remove the need for various headphone amps to have things to power different headphones, from things like Denons to Orthos. I found most headphone amps that can perform well on both are insanely expensive, compared to a $219 speaker amp with a volume knob that essentially does the same thing. So I have to recable or use adapters to use it, not a big deal to me, as I'd still rather use it than a headphone amp at this point since I have a setup that powers both speakers and headphones, and when I outgrow it, I don't have a brick sitting there that can't do anything except power a headphone. I like that I can swap speakers onto my LDMKIII -> Emotiva and have a tubey speaker setup too. Let alone headphones. Headphone amps are relatively new as it is, and frankly, are just low gain, low powered speaker amps, that are over-priced. I'm sure some golden-ear folk with absolutely disagree with that. But speaker folk probably would understand more why I would comment that. So far, I'm hearing excellent results from very budget friendly things that compare very much to some higher end equipment that I've listened to, so I'm enjoying the extra hundreds not spent on more headphones and more music instead of just more "gear." Universal balanced adapters and cables are simply awesome too. I just get my headphones modded to XLR balanced and I can use anything I want.
Maybe it's not summit-fi worthy, which is why this thread was moved.
But I'd love to put some of them up against this in a blind setup not knowing what they're plugged into.
