Hi AK members,

Stereomojo.com has published the review on our A-534B Single ended triode integrated tube amp with full set of upgrade tubes. The review unit is currently in the USA and I rather sell it to a USA customer at good price than shipping back to Canada and waste on shipping and duties.

Instead of the standard Shuguang clear glass tubes, this review unit comes with a complete set of upgrade tubes, including:

- pair of Shuguang Treasure 300B-Z black bottle tubes
- pair of Shuguang Treasure 6CA7-Z black bottle tubes
- pair of TJ Full Music 12AX7 gold pin tubes
- single Shuguang 5U4G rectifier tube

An auction is on AudiogoN now if you are interested in participating. (http://cgi.audiogon.com/cgi-bin/auc.pl?intatube&1251077219)
The unit full retail value is US$2500 but auction starts at US$1700. If you don't want to wait for the auction to ends, you can purchase from our website for a 'buy it now' price of US$2000.

It comes with headphone jack right off the 300B circuit. You will have one of the finest headphone amp you can find on the market plus all other benefits of getting a single ended triode amp.

This amp will work with all speakers at medium volume but will really shine with high efficiency speaker, especially horn loaded speakers such our Shengya V218 / V518 speakers.

Ian/Rachel:  did this amp sell on the auction?

It did, and I'm enjoying it very much!

It sounds fantastic with my Omega super 6's and my Sennheiser HD800's. Win, win!!

Awesome Santacore!  Congrats.  I've almost pulled the trigger to try the A-534B a couple of times.  I've never had any SET amp; now that my spkrs are the efficient Daedalus Audio DA-RMa's I'm so tempted.

I have a quad of the Blk Treasure 6CA7's in my Cary SLI-80 as outputs tubes, as well as the BT CV-181z's in it as driver tubes=Ian & Rachel have made a believer out of me with regard to the Black Treasures and I'm thinking I will trust their judgment regarding amps as well  !

Enjoy,

Randy

Randy,

I hesitated many times too, so I understand. In the end I took the leap of faith, hoping that the positive reviews were fairly accurate. Thankfully they were and I have a great new stereo.

Those Daedalus speakers look incredible! If they sound half as good as they look, you've got a sweet rig. The A-534B would likely be a very good match for those beauties. If you haven't experienced a good SET amp before, this unit would be a heck of a surprise. It's rich, spacious, and extremely musical. It's basically everything I want in a good tube amp. Now, I don't know exactly how much those Black Treasure tube effect the sound, but I would guess a fair. Since I couldn't hear the before version, I'll have to trust the reviewers that did experience both.

One last point-Ian and Rachel have been great to deal with. They are quick to respond to my e-mails and have addressed all my concerns. I wouldn't hesitate to buy from them again.
