I am a big fan of the Micro ZOTL as well. It powers my 8 ohm, 93db speakers quite well and it also works as an incredible preamp. And then there is the ZOTL10.
Any options for low power class A amps?
Okay, I do most of my music listening at work because of time constraints. I have a nice desk system that includes some 4" Fostex full range speakers, an Olasonic dac, an Olasonic cd transport, and an integrated Olasonic amp/dac. I have nothing but good things to say for Olasonic however I would like to add better amplification. I am looking for a small solid state amplifier that is pure class A in the 5 to 10 watts range. The only ones that I have found have a higher power rating and are huge or are A/B amps that are biased slightly higher. I don't know if anyone makes class A amps in this power rating. If you know of any I would greatly appreciate your help. I have tried headphone amps that are pure class A that results in an improvement but the impact is not there due to power and impedance matching of speakers in comparison to headphones. The Fostex drivers I am using are 16 ohms btw. Thanks.
