Plinius SB 300 v Plinius SA 250 MK IV

Although I haven't received any responses in this form I have received some emails and had some phone conversations with some audiophiles that have heard the Plinius SB-300 and the Plinius SA-250 MK I, II, III, and IV.
Bottom line is I have ordered a Plinius SB-300 and hope to have it in ten days.
If anyone is interested I have a Silver Plinius SA-100 in excellent condition with original manual and box that I will be selling (and listing on Audiogon along with a Forte 4A) as soon as I receive my new SB-300.

It will be good to test the sa100 vs the sb300 before you sell it and also let us know.

I have been a tube amp guy since 1986 and bought Harbeths a few months ago. They need more current than my Air Tight 300B can give so I bought an SA-50III. Maybe it's the Harbeths but I didn't know S/S could sound so good. Then again, maybe it's the Plinius.
