I suspect the Cayin HA-1A is actually more proven than the Doge. Cotdt your excitement for the Doge is getting a bit exaggerated. The Cayin has been around quite a few meets. I was very impressed with a variety of phones, though unfortunately I wasn't big on the K701 at the time. It's certainly a great all-arounder and usable for the K1Ks or speakers.

In this price range I've gone the Woo route, but there are lots of good options.

Cayin HA-1A pairs well with the K701. It doesn't add too much warmth but the amp has more speed and resolution than is typical of most tube amps. Lots of power in reserve. And it has a nice mid-bass punch too.

I heard once the Cayin with some Grado SR225, very nice sound...
TTVJ had a great price and a 30 days money back guarantee

I really like the looks of the Cayin. A bit pricey for me though.

I like the looks, and the small footprint as well.

I think the Cayin is the way to go. For something cheaper, you can try Darkvoice.

Some swell photos of the guts.
The thing about the Cayin is the output impedence selector switch.
You can toss any input into a tube amp but they are fussy on the
output side.Glad to see someone has addressed this issue.I have a
whole gaggle of cans from 8-2000 ohms.The Cayin is tempting.

Spiritsound is a great place to do business and is run by Richard Moulding, a man who has the highest integrity of anyone I have known in the audio business over the last 30 years.

The Cayin is also very well made.

Blackbird Audio also carries the Cayin. http://www.blackbirdaudio.com/
