Ok, time for some amp impressions. For me at least, the amps were the most interesting part of the meet, as that is my next investment. So here goes:
Singlepower PPX3 Slam: I really liked this amp. I really really liked this amp. It had it all and sounded great with every phone I tried it with. It drove my K340's with authority and power. The texture control was interesting. I found my favorite was with the control set around the 2:00 mark. This was certainly my favorite amp there.
Teerawit's PINT and PPAS: The PINT was a fun little amp. Running at 24V, it was a punchy little amp. It had a fair bit of power behind it (though I would have had the gain a bit higher than 4). It wasn't quite as refined as the PPAS, but I felt that it was livelier. Unfortunately, the PINT began to oscillate for some unknown reason and my listening session was cut short. Overall the PPAS was the more balanced amp, but I think I preferred the PINT, but as stated, I didn't get a chance to do a thorough comparison.
RSA Tomahawk: I brought my Tomahawk to the meet to see what everyone thought. It proved to be a little marvel. Sure, it clipped on my K340's with the volume around the 12:00 position at high gain, but that was an exercise in futility. With more forgiving phones, such as Grado's or my DT-770's, it sounded much better. I didn't listen to it as much as the other amps, because it's mine and I will get a more thorough review later.
Benchmark DAC-1 integrated amp: This amp wasn't impressive. The sound quality out of that amp wasn't that great. I'd say it didn't outperform any other amps there. It is better than nothing, but every other amp I listened to outperformed it. It will work in a pinch, but if you have another choice that's better than a CMoy, use it.
