Plinius class A vs. class AB sound difference?

I own the SA-102, so I'm not sure if my observations will be the same compared to the SA-100. I can hear a distinct difference between A and AB, although much of the sonic character is maintained in both modes. Class A provides a more focused, layered, and densely populated soundstage, the bass has subjectively greater reach and better pitch, the highs have a more crystalline quality, and there is slightly more warmth and body. Class AB sounds great as well, and is possibly more open, although less focused, and slightly more forward sounding. Even though the SA-100 is only rated at 100 wpc vs. the 8200p's 175 wpc I would think that it is capable of more current delivery than the 8200p due to its larger power supply.

I agree with Judit: you owe it to yourself to hear the SA102.

I traded up to the SA102 from an 8200 integrated. For the money, the 8200 is great, but no match for the SA102. The 8200 is rated at 175 watts at 8 ohms, and the SA102 is 125 watts at 8 ohms. But the SA102 is capable of delivering something like 4500 watts at clipping and even the gutsy 8200 can't match that. The SA102 can really swing that woofer like no other amp I've heard (except the SA250).

As to your question, Symphony Sound is theoretically correct, but I admit I can't hear a difference between A and A/B on the SA102. But who cares - this amp is awesome!

Here is another vote for the Plinius SA-102. As far as your question on the difference from A/B to class A, in my system it's quite noticeable. Much more subtle detail and more spacial clues. The definition of each note is more realistic. I must advise that on my older less revealing system the differences of the original SA-100 were not as pronounced but still easily discernable. I would not advise anything less than Class A if your looking for the ultimate and your system is capable of delivering.

I totally agree with all review before me on this forum,
its obvious they own and indeed they are full of information
and i learned too. Thanks you guys.
Let me just share, to my experience with my plinius
mark 11 when i played to AB its really good, but to me
switching to A its a differrent level of listening,IMHO i
notice the first 10 to 15 minutes after switching to Class
A i dont hear the difference too, at least 1 hour after
music began to involve me more,it disect the inner part
of the emotions of the music,more transparent and clearer.
but i believe i like the Class A mode.
anyway thanks again.

Does the Plinius 102 run hot in ab mode ?? --- I have a problem with a heater in the house during the summer months, and was hoping to be able to run it in ab mode and still get good sound.......
