suggestions for a headphone amplifier

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?

IIRC, Moth headphone products are now sold under the Eddie Current (cute, huh?) name. I think there is/was in the under $500 range. You may want to try headfi.org for used amps and reviews of virtually all hp products. And Rocco, if you can stretch your budget to about $700 you should be able to find a used Audiovalve RKV MK2, which is an OTL amp that to my ears has more punch and more definition than the ASL amps.

IMO the Senn 650 has a smoother, richer midbass and better balance than the 600. I find the midrange of the 650 is flowing and the highs are smooth, with a slightly dark presentation. To me, the sound of the 600 is generally similar to the 650; however there are some slight differences - the 600 treble is grainier, the midbass is boomier, and the bass is less robust. I also find the 650 to be more comfortable than the 600 and I have less listening fatigue with the 650.

Also, the MF X-Can does not lack power to drive the 650.
