This seems like a very honest and polite question. I don't think M-13 was trying to "put you against the wall" or "discredit you". When we started hooking up the emotiva to headphones, the way to judge it was that everyone was comparing it to other amplifiers they had. It's a great way to see the value in an amplifier, and where they sit compared to others.
2. Just because something is loud doesn't necessarily mean it is getting enough quality power, especially with orthodynamic headphones. Read through the few hundred pages of the HE-6 amplification thread to read more.
3. The emotiva has been compared to many different amplifiers at this point, including very powerful tube amps. In my experience it easily outperformed the Burson Soloist, which easily outperforms everything in the sub $700 range.
Or ss amps of the like of violectric v200, musical fidelity, burson etc.
This is such a strange mix of amplifiers to suggest. For example the Taboo is a speaker amplifier that costs $1.8K. A cavali liquid glass is one of the best amplifiers I have ever heard. But it also runs $3.5K.
The bottlehead crack is obviously not suited for any orthodynamic driver. Most tube amplifiers are not built for low impedance headphones. It's rare to find a tube amplifier that is built for low impedance headphones and is powerful. Which naturally begs the question:
Why use the DV337 with the HE-500? The DV337 is a long running favorite among those who love their high impedance headphones, and notorious for not doing well with low impedance.
............ I don't want to point out the obvious here, but
I'm not sure what you're trying to say here, but needless to say, it's pretty speculative.
