Looking for 300B SET (one output tube per channel) to pair with Shindo masseto pre amp. How would you compare Wavac EC300B, Shindo WE300B, Yamamoto A-09S and Verdier 300B?

What is your take on the best cost no object 300B SET?

Johnk/Sounds-real....if you've heard the LM mono 300B amps, I would LOVE to hear your impressions...

I run an AirTight ATM300 8W SET (WE300B newer production, Genalex GL B749 drop ins for 12AU7s, RCA red label, grey plate 12BH7s & 1940s JAN RCA black plate 5U4G) and am saving for the LM 755i's...
Asa,
The LM755 field coil speaker with your Air Tight 300b amplifier would seem to be a potentially superb combination.
