siltech 550i

The are very good cables. transparent, open and never harsh.
They might sound a little light in the bass in some systems.

Dsholl1,
I think you may consider going with the non bi wire 330 with jumpers.
The bi wire cable are thinner than the non bi wire.

I had the 330 for a month and than upgrade to the 550 and use it for a few month and ended up with the Prince (signature line).....
They all have the same house sound of siltech, but going up the line you get more of the same - which is what you want: more dynamics, contrast. naturality and body.
The 330 was too lean in my system, though it is a very good cable and will sound very good in other systems.

I had or listen to: JPS, Transparent, Synergstic, AudioQuest, Harmonic Tech., and Acoustic Zen.

In my system the Siltech was better than the others (though the 550 and 330 do not have the dynamic and bass of the JPS superconductor+, but are more natural, open and transparent).
The Siltech Prince is way better than all the others.

I have Accuphase. and I think SS "need" this kind of cbles more than many tubes amps.
