I came across this amp while browsing through eBay :

Fournier HTA-1 Tube Headphone Amplifier - eBay (item 260550585149 end time Mar-10-10 18:45:26 PST)
[size=xx-small]
Designed & Made in USA

JJ 12AU7's (NEW) Preamplifier Cascode with 20 dBV gain

Solid-State Mosfet Output Stage with 0 dBV gain

Zero Feedback

<1% THD

10k Input Impedance

35 Ohm Output Impedance

50mW Output Power into 30 to 600 Ohms

20Hz to 20kHz 1dB BW , 1st order roll-off

RCA input Jacks

Gold Plated Ceramic Tube Sockets

External Power Supply

Tubes are Self-Biased Allowing Interchange for Favorite 12AU7 (JJ 12AU7/ECC82 Tubes Included)

High Quality Construction

Anodized Aluminum Chassis

It's cheaply priced but there's zero information so far that I can find about it's performance.

I'm wondering if '' Mosfet output stage '' here means a discrete one or simply opamp based.

What do you guys think ??

Did you have any specific questions about the HTA-1?

Hmm, seems like a well built amp. Wonder how this compares to the Hifiman EF-2 which uses the same family of tubes and costs around the same.

The EF2 uses a pair of 6J1's, which AFAIK isn't a 12AU7 equivalent. The EF1/EF5 uses one 12AU7, but that's a whole different price range.

Pity I just found an amp for the office...this might be quite tempting otherwise.
