Upgrade speaker cables OR amp for Dynaudio C4's?

Well, I went over my budget and have cut a deal for a second Plinius SA-102 to run as a bridged monoblock with my current SA-102 amp. I'm cautiously optimistic that going from one amp @ 125WPC to two bridged monoblocks @ 400WPC in 8 ohms will help me get the most out of my C4's (within reason considering the mega-dollar SS amps from MBL, Lamm, Levinson, Krell Evolution, Boulder, DartZeel, etcetera) .

I'm also ordering Silent Running Audio (SRA) isolation platforms (VR series) to put under my amps and preamp. I've never really invested much in isolation gear, and the inexpensive tweaks I've tried just seemed to dull the sound. From all of the reading I've done, SRA seems to be the "real deal" when it comes to isolation platforms.

I'm crossing my fingers that these new additions to my system will take me to a new level of satisfaction.... worst case, I'll look at the silver lining knowing that all of these components have strong resale value!

Did you check with Plinius before the decision on bridged monoblocks?

Many manufacturers do not recommend running their monoblocks bridged with loads under 8 ohms.

Dynaudio rates their speakers at 4 ohms but some are closer to 3.

I'd be very careful.

Dealer disclaimer.

Generally speaking, I have heard that bridging an amp tends to diminish the quality of the sound as well:O)

Bill & Dave - Audiogoner Jadem6, owner of Jade Cables reviewed and still uses this combo with his Dunlavy IV/a's with good success. Jade & I also both use the Aesthetix Calypso.

The C4's are rated @ 4 ohms nominal / 3.3 ohms minimum / 88dB.

The Plinius SA-102 owners manual states that bridging them as monoblocks will "provide and extremely high performance option". The manual goes on to state that care should be taken when matching speakers... "the total average impedance for each chanel should in a range between 4 & 8 ohms" . So hopefully I'll be okay ???

If I'm wrong and it does not work out, at least I have two amps with good resale value.
