[CLASS A]

Dear all,

I m using the Plinius SA250 IV ( 250WPC class A) per channel to drive the JBL 250Ti jubilees. My question is, what sort of improvements if any if I buy another SA250 and go mono. The SA250 will produce 1KW per channel in banlance mono mode and the Jubilees can handle 400W. Is this over kill or am I wasting money?, I m sure you guys out there must have tried the mono configuration with the JBL 250ti.
Thanks in advance.

Hello Class A

Do they sound like they are compressing on peaks at a bit above your average volume setting??? Only you can tell that depending on SPL, room size, and of course what you listen too. Try an evaluation with a demanding passage in mono one channel only in stereo mode, then strap the amp and replay.

Thanks for that, they don't sound at all over strained even at high levels. At mo, the volume switch starts at 7 o'clock and the loudest I ever used is at 12 o'clock and that is killing my ears ( complaints from next door ) .
I suppose I m not looking for more volume but more dynamics, drive and sheer kicks from the JBLs. Would image and soundstage improve upon more disposable power on tap?.
Cheers

In my own experience with Class A the only further improvement may be bi amping if you can.

Its unlikely a the class A amp of that size would ever sound compressed as its a hi current amp by design.

Thanks mate....what are the pros and cons between mono config and bi amping?, and with bi-amping, would I need to have both amplifier the same output or can I use a smaller amp for the mids and highs?.
