Upgrade speaker cables OR amp for Dynaudio C4's?

The SA-102 owners manual states input impedance @ 47K ohms. I'm using single ended cables... am I okay?

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)
