Hello Jonchew Ive also got a plinius sa 102 [2- one silver and one black serial #s 2173/1865] in mono and a p-8 for my center along with an sa 100 mk3 on surrounds in a hometheatre setting, personally ive not tried many preamps only an Adcom gfp 750 with my initial Plinius sa100mk3,that with a Kora hermes tubed dac using Pearl cryovalves"1975 nos cv2492/ and 1964 mullards matched pairs , also have a Magnum Dyn. 102 triode tuner using amperex bugle boys matched pr.What Ive done is use pliniuses M-8 preamp along with tubes in my source, thus tuberolling to audibly tweek sound to my liking. Many like pliniuses sa poweramps; me also, however the preamp seems not as highly regarded but for me with theyre hometheatre bypass and rich dynamic sound ,its a perfect match as it was designed to go with theyre poweramps.So with all due respect to Mr Jadem6 as hes assembled a very nice system dont count the M-8 out as a synergistic match as the company intended.P.S. I personally did not want to go through endless hours auditioning different preamps so the M8 was a easy solution and in the last 18 months of use has provided me with endless hours of musical enjoyment.NO REGRETS! Good luck in your quest!!!Regards Tim W.
