300B tubes

Jfrech - thanks! I love this amp - simple, small, sounds terrific. I have a VPS and PLP now too. Any advice on interconnects or power chords? Have you tried any battery units for the VPS (ie Red Wine Audio). I use stock cables. Also, what speaker cable was your dealer using in your listen on the 300p/i?

Thanks for the tube advice. The Sophia Royal Princesses are the most expensive tubes I've seen! I will look into them and call Sue. I may experiment a little with the Gold Lions first as a "reasonable" starting point.

Further input absolutely welcome and thanks.

So I love the Transparent Cables. Some of this might depend on your speaker choice, but they are just wonderful for me. Power cords I am using Shunyata again a great match.

Powercords are a big deal with Nagra, I've also found the power supply on your VPS likes good support (cones etc). Are you using the VFS shelf like your 300p amp has? It really helps the PLL and VPS (I stack these two-see my system pics)

I did try the red wine power supply. It really helps the VPS. Lowers the noise floor, everything is smoother, better flow to the music, better details. I'd go this route over a power cord.

Good luck on the tube hunt!

There are 8 of KR tubular type 300B's right now on sale for USD1300 ONLY! They are superb to all that Chinese WOW tubes, imo.
The seller dont want to sale outside of US, otherwise they were all gone.

Good luck.

In regards to reliability, no issues with the Shuguang Treasure 300b tubes in close to two years of everyday use. Nice sounding. I had KR 300b's a while back. I strongly suggest a search on audiogon first.
