Actually, no.

Psvane is an offshoot of defectors from Shuguang. The giant that is Shuguang still very much exists, and they still make and sell tubes. Many more than Psvane, in fact.

Quote:
Shuguang is the oldest and largest tube manufacturer in China, established in 1958 by engineers educated and trained in the United States in the 30-40s. Shuguang’s vacuum tube production accounts for the world’s 40% total tube output nowadays, either under their own brand “Shuguang” or under OEM brands.

Generic Shuguang tubes come in clear glass enclosure. The ‘Shuguang Treasure’ series comes with carbon compound coating inside the tubes making them appearing to be ‘black bottle’. They are only released in Dec 2008 to celebrate Shuguang’s 50th anniversary and technology advancement.

After launching the 50 year anniversary Treasure series in 2008, a team inside Shuguang has been developing new additions to its high end tube line to include large power tubes and small preamp tubes. With venture capital from UK and countless testing by Treasure series’ original design team, a new series called “Psvane” (pronounced as ‘Pavane’ – the brand is created from the inspiration of the 17th century classic music dance) T-series has born in Aug 2010. The Psvane series is a further fine tuning over the Treasure series, and the brand is owned by a separate entity other than Shuguang Group itself. Since Nov 2011, Psvane brand has officially become independent from Shuguang and production has been removed from Shuguang. New Psvane Audio manufacturing facility was acquired from Guiguang Tube Factory.

I was a little late to the party but there is a fair amount of noise going on about the TBI Millenia MG3 Class BD integrated amplifier based on the Texas Instruments TPA3100 chip. All of the Tripath chips are obsolete at this late date. As these newest generation TI digital amplifier and similar chips get developed into mature extremely high quality amplifiers over the next few years, it looks like a permanent end to all class A and AB solid state and vacuum tube amplifiers as we know them today. It also looks like full range speakers have a very bright future. Just my prediction.

No, I have had the original, genuine Tripaths and in my opinion, they don't belong in the same class as the best linear amps. The only Class D amp that does is Hypex nCore.

Also, the Class D amps are terrible matches with fullrange speakers in my experience.

I've got a Tripath (TPA2020) in my bedroom system and it has earned a permanent home their for low to mid volume movie/tv/music duty, but when I plug it into the living room system it makes me laugh, then nearly cry. At anything past 1 o'clock it just sounds like a complete joke.

My tube amp isn't going anywhere. People thought SS would kill tubes, but they're not dead yet. To think class D will kill SS and tubes seems pretty funny.

The TBI Millenia MG3 Class BD integrated amplifier with the Texas Instruments TPA3100 chip has actually been around a few years. The new Texas Instruments TPA3116D2, TPA3118D2, and TPA3130D2 chips are the ones that may rival the Hypex nCore amplifiers for sound quality though at a much lower cost. Many are selling their expensive amplifiers already due to the MG3 and these new chips should prove to be much better.

I don't think it is because it is a class D that is the problem. The 2020 is really a nominally 6 watt amp into 8 ohm loads (where distortion is very low). At volume settings above the 1 o'clock setting you are pushing it into high distortion (10%+) which is where they quote the 25 watt rating. I think if you were to use a class D amp rated for 50 watts it would probably sound fine in your living room. In terms of actual production units to the masses, solid state has essentially taken over tubes which are now only in the realm of high end and audiophile use. No major electronics manufacturer produces amps with tubes anymore (jvc, sony, matsushita, phillips, etc.) I would guess the market share of tubes is less than 1 % compared to SS. However, with that said, on this forum and amongst the audiophile community, tubes are very much alive. It just depends on the sample you look at. I am not saying which is better, just the fact that SS really has taken over the old tube technology.

Where can I buy these TPA3116D2, TPA3118D2, and TPA3130D2 modules to try?

But they do not use the same chips as the new TDA ones. Well, maybe hifimediy.com will come up with modules using the new chips.

You can get the TPA3116D2EVN Evaluation Module or board from Mouser Electronics. The other 2 boards are also available from them if you are interested in the lower powered units. These chips were made available just last July and I don't know that any printed circuit boards have been designed for them yet but it would be extremely nice if someone would get the ball rolling. These new chips have great potential. Vacuum tubes could possibly become obsolete once and for all.
