silver with tubes and copper with solid state ??

That is kinda funny. I thought the 308 was beautiful in hindsight, but I didn't want to have an integrated plus a multi channel in my setup. Never seen something sell so fast as that 308 did though, it was gone in 4 hours after I listed it.

I've demoed an Anthem Statement A5 at home, owned an Outlaw 7100 and now this Sunfire TGA5200. None of the aforementioned are truly the be all/end all in amps, but a few aren't slouches either. The A308 was incredible, although it took the right cables. I tried Cardas Golden Crosses which were intolerably bright with it (and I hear their supposed to be warm....I didn't thing so anyways), but the AZs were just perfect. It wasn't as picky with power cords or conditioning as the Sunfire. Wonder if that's because it was choke regulated?

Everyone has different tastes so it's just a matter of trying different ones till you like what you hear.

It all comes down to synergy.

I have one SS rig that uses Goertz AG2(silver) and is far from bright due to all warm components. Meanwhile, in my tube rig, I use copper cables due to a bright source.

As mentioned before, it all comes down to what sounds the best to you.

Like some of the others, I too have a hodge podge. I'm currently using Cardas Golden Reference phono cable (copper), Ridge Street Poiema 3 interconnect (silver), JPS Superconductor 3 speaker cable (copper coated aluminum and copper) and Ridge Street Poiema 3 Signature power cord (silver). And I'm getting a detailed, dynamic, musical, you-are-there, no glare, free of fatigue sound. My electronics are tubed: EAR 88pb phono preamp and modified Air Tight ATM-3 monoblocks.

Somewhat on the topic, I just picked up another Taipan Alpha Helix cord (this will make 4 in total combined with a Hydra 4 in my system). I believe this version is with copper mains and EIC from looking it over, but I haven't confirmed that with Shunyata yet. Matching this cord with the Benchmark DAC and moving the silver plated Taipan Helix over to my pre/pro and the nickel Taipan Helix to my Sunfire amp (I've another Silver Taipan 20amp feeding the Hydra), it has warmed things up considerably. I'm still completely floored after all this time that power cords can lend almost as much impact as ICs since the notion they'd have any impact at all sounds ridiculous at face value. Benchmark engineers have stated their DAC is immune to AC interference and doesn't need aftermarket cords, but honestly it's more than evident what impact different cords have on this DAC and every other piece of gear I've had.

I've a pair of AZ Silver Reference IIs on there way so we'll see what they can offer, but I think I solved the brightness issue enough with the new Taipan cord power cord. I'm not here to pitch Shunyata gear honestly, but their helix cords are worth a try if you're also looking at ICs to alter tonal balance.

First; speakercables needs to be elaively thick and massive. 12-13awg is a good start,suitable for tweeters & smaller midrngs. In my system I`ve ended up using 4x9awg (x2) for the woofers, 2x9awg for the 6,5" mids aso.
Remember; speakercables must be sen as a par of the amp`ssssssssspowercrcuit. This low-current powercircuit can`t control the speakers through thin/flat/stranded wires, even th most poweul amp won`t do.

Underdimensioned powercircuit is lo the main reason why some amps are less dynamic & powerful than others.
