suggestions for a headphone amplifier

Of course this is only MY opinion and based on MY tastes, but I have tried a TON of different headphone amps and the BEST I have tried with my Senn 600s and 650s is the Moth Audio S2a3. E-mail me offline if you have any questions.

I'm currently using the Grado 125's with the Antigue Soundlabs amp. Sounds great for what i use it for. Highly recommend the Amp. There are better headphones out there than the 125's but they work fine for me.

Answer to Swampwalkers question: 500.00 or less. I am intrigued by the Earmax pro, and now exploring the Headroom offerings. These amps could conceivably raise the bar as far as dollars and cents. I am amazed by the scope of their products. Talk about ruling an audio niche! My preference is to find a nice second hand amp as my bucks will go further. Please keep them cards and letters coming, and thanks for reading.

I'm running my HD650's with A.N.T. "Amber". Designed and built in the UK by Alex Nikitin, the man behind most Creek components in the last 10 years.

I'm also looking for a new headphone amp. I currently have the Grace 901 which is a fine amp but I'd like to try a SET headphone amp. Is Moth still in business?
