tube headphone amp?


I was just informed that I may not be able to get a headphone amp that I was seriously considering, the Audio Valve RKV Mk II. It's being "upgraded", (waiting to hear reviews + what the price will be). I'm currently using a MF X-CAN v2, so the only criteria are: it must be tubed, and it must be an upgrade from what I've currently got. So here is my short list, any additions/deletions? Let's start with a price-no-object list, I can whittle down from there: - The Earmax Pro; - David Berning Co. sells something called the microZOTL, but direct only; - that Cary preamp that Headroom claims is the best in the world; - Wheatfield Audio HA-2; - Antique Sound Labs - the MG Head DT; - Zeus OTL Headphone Amplifier by Fuchs Audio Technology; - Holmes Powell;

I currently own the Antique Sound Lab headphone amp. My prior set-up was X-cans w/X-PSU power supply. The Antique blows the X-cans out of the proverbial water - in ALL parameters (and is cheaper @ $260.00). UNBELIEVABLE sound for so little coin. Using with Sennheiser HD600.
the headfone amp in the melos sha-gold or maestro reference preamps are continually raved about by the audio press. an outstanding line-stage comes attached, too! ;~) their sha-1 is also excellent. doug
I'm taken care of (thank you Brooklyn Audio), but for anyone else who's reading: Add EAR to the list. It may not be on their website, but I received an email telling me that they do indeed now sell a headphone amp. It's really nice that a lot of these manufacturers sell preamps connected to these headphone amps.
