Plinius SB 300 v Plinius SA 250 MK IV

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.

The Plinius is very tube-like. My reference system consists of the Cary 2A3 monoblocks.

I had cary 2A3s 5-6 years ago but could not find a speaker that worked. The Cain & Cains were not available then. I found the Air Tight had enough oopmh for many more speakers. I also had Cary 572s which were really good sounding but those damn tubes died every 6-8 months.

Here’s the follow-up to my posts:
I received my Plinius SB-300 today. After setting it up and cleaning all contact areas with “Kontak” and then spraying with “ProGold G5”, I powered up the amp.
I was cautioned to give the BS-300 a good 30 days to reach it’s full potential (as was already my rule of thumb) I’ll leave the SB-300 on 24/7.
I think the Plinius SA-100 is a damn good amp whether running it in AB or A mode however for this comparison the SA-100 was warmed up and operating in A mode. The SB-300 was set up out of the box and I heard the following from the SB-300 as it’s been playing now for 2.5 hours and sounding improved the longer it plays.
The following are the immediate improvements:
1) More bass slam with a greater bass range.
2) More resolution overall.
3) Greater attack and improved details and imaging.
