I just finished A/B testing this amp verses the Red Wine Audio Signature 30.2 LFP-V hybrid integrated amp, and I think it's a draw... Both the Red Wine and the Shuguang Treasure 300B are fantastic with the horns; where the tubes error on the side of musicality, and the hybrid errors on the side of analytical. After burning in the Red Wine and rolling a few tubes in it, my conclusion is both amps sound VERY GOOD, but they present the sound stage and body of the music very differently. The Red Wine amp came close to the Shuguang Treasure's musicality on battery power and running an NOS Amperex 6922 Holland, but Shuguang Treasure 300Bs are a special tube. The Shuguang is still the better of the amps musically, but the battery powered Red Wine has a completely silent background coupled with SS bass which is addicting on horns. My 7 month old daughter is also starting to move and grab which makes a high-voltage tube amp not good as my equipment is in the middle of the family room out of necessity. I would never consider paying more for a 300B amp than this Shuguang as this amp sounds fantastic and does everything a 300B is supposed to; and the upgrade doesn't hurt either. :biggrin:
The amp is sold by Grant Fidelity, and is the most musical amp I've ever owned. It has four sets of inputs, plus a hard power button, and an ON/OFF button which energizes the tubes allowing the electrical components to always be powered up. The amp is in very good condition, and remote has only been used to program my Harmony universal. It comes stock with Shuguang Treasure 300B and 6CA7 tubes, and I upgraded the 12AX7s to Psvane, and upgraded the 5AR4 to Shuguang Red Base for longer life. I also upgrade the amp with Jantzen Silver/Gold coupling caps, plus other Jantzen Silver Z-caps in key location for increased sound quality and clarity; and at the cost of $700. The amp and original Treasure tubes are about 1 year old, and I have extra tubes for the amp, as well as original double box and foam packing materials for a safe trip to anywhere.

-Matched pair of Shuguang Treasure Premium Grade 300B-Z tubes (600 hours)

Update:
The trade with Troy fell through, so this amp is back on the market baby! In the process of working with Troy, I realized that the Tuner input select button on the amp does not work, although it does on the remote. Given that I always switched between the four inputs with the remote, I never found this an issue, but I have adjust the price to reflect this "flaw". I also have an extra pair of silicone tube dampers which I will be including with the upgraded Psvane 12AX7 tubes.

Bump from TNT audio: So Shuguang have been making valves for 50 years, and supply 40% of the world's audio valves Most as OEM production. With that sort of background I suppose it's no surprise that they've produced some pretty spectacular valves under their own 50th Anniversary Treasure range and the 300b-z is a worthy addition. I've felt it necessary to compare it to the best of 300b's you can buy and it's certainly held it's own and ranks right up with the best currently available.

I know someone here needs a SET tube amp like this beauty! This tube rectified, 300B driven by 6CA7 amp can turn any sensitive pair of speakers into pure music...
-
Any comments or feedback on this amp? Is the SET sound just not popular right now?
