300B tubes

I'm considering tube rolling on my Nagra 300p. It comes with 4 JJ 300bs, and I am curious about the Gold Lion re-issue 300B (had a great experience with their KT88s in the past). I am also considering the re-issued GE 300B and the Shuguang Treasure. Reliability and sound are both required in this price range. No troubles with the JJ - just curious to experiment.

I've read prior threads and searched the net. Thus far, very little on the Gold Lions, lots on the Shuguangs. Cheers and thanks.

Hatari,
One thing to keep in mind is that some 300b tubes mate better with certain amps than others.
In general I can state that the Shuguang Treasure 300b has been a wonderful tube with my amps. Superb sound(very natural-organic) and ultra reliable nearly daily use for more than 2 years and not a single issue, none!Worth every penny IMO.
The Sophia Royal Princess has gotten great reviews and could be very special but it`s quite expensive(1200 USD).
In that price range there`s the Japanese Takatsuki 300b to consider.
Best of Luck,

I purchased 2 pairs of the GL 300b for a push-pull I got recently. I like their sound and they behave perfectly.

Some tubes just work better in certain circuits. Staying south of KR/EML/WE prices, I like the Sophia Meshes also.

"Some tubes just work better in certain circuits.”

I agree. I’ve also heard the same from some amp designers of note. FWIW, for me, the Sophia Royal Princess has been right on the money. And from what I recall of my auditions with Nagra (some time ago), I would find some way to listen to this tube in your amplifier. Talk to Sue at Sophia. I’ve known them to be very accommodating.

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?
