Get the Doge 6210 at pacificvalve.us for $425 plus shipping. A USA dealer who has no ties to Cattylink.com.
I have never dealt with pacificvalve in any way.
I can't show you the amps I have recently owned or the related equipment I own, which wouldhelp others know the basis of my evaluaton, because the administrator here deleted that info in my signature as an eyesore.
I currently own Bada 12, Doge 6210, and Jolida JD2A headphone amps with the K701 and the Rega Saturn CDP. I have owned the following amps over the last year: RSA RAptor, ASL MG MK III, Xian Sheng 708B, Ming Da MC66AE, Woo Audio model 3, Woo Audio model 2, RSA Hornet, Lehmann BC linear, Headroom Cosmic, BLAudio LP MK III (currently owned and used in my car with the ER 4S). I have owned several Stax, the HD650, Beydynamic, SA5000, and many other HPs.
People who have owned the Bada 12, and Doge 6210, and Singlepowers, report to me that the Gada 12 and Doge 6210 is at least as good, if not better, than their Singlepower models.
I have helped many people achieve great sound at a low cost while offending those who paid more.
I recommend the Doge amp for $425 plius shipping at pacificvalve.us and would recommend using these tube combos:
Two Electro Harmonix 12AX7 and two Russian military 6P14P EB
Two GE 12AX7 long plates (17 mm only) and two Shugaung 6P14 (EL84, which come with the amp).
I recommend components solely based on the best bang for the bucks. I offend others because of my honest and frank evluations which sometimes makes their purchases look bad and wasteful.
I have already had one PM warning me to leave this site, now!
Another promising amp is the Yarland P100 for $350 which uses two 6N3 (5670) and two EL84 tubes. Do an online search for the dealer in the USA that offers this price. As with the Doge 6210, the amp does not sound its best with stock Chinese tubes though some of these tubes can sound good when properly mixed with NOS tubes.
Those about to buy an amp, who follow my advice, will be well reward - I get Emails all the time from happy purchasers.
