Class A is hard to find "small". How about the Parasound Zamp? It gets very good buzz, and quite small. Otherwise, not sure if you need it small in 3D or just 2D (i.e. small footprint) you could probably find some small SET amps.
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.
