Siltech cable guages i.e. AWG

I was just talking with my dealer and he does not have any specifics about cable gauge and Siltech will not provide this information. He has tried and they have responded to my e-mails saying they won't disclose that information.

My dealer has both the 330L and 770L speaker cables and oddly enough they are the same thickness. He didn't have the 770L's on hand when I was by as they were lent out but he said the odd thing was even looking at the termination ends the cable thickness of the 2 models even appeared the same. So there is no difference in appearance but he said a definitive difference in sound.

He doesn't have any of the Royal Signature cables on hand but I'm now very curious if say the Prince and King for example are also indistinguishable from each other or is there an obvious difference in thickness between the two and does this continue as you move up the line? i.e. Emperor, Emperor Crown and Emperor Double Crown. Is anyone familiar with the Signature line that has seen these cables side by side? I would be curious about the Signature interconnects as well because he said like the speaker cables there is no physical difference between the 330i's and 770i's which I was able to take a look at and he does appear to be right.

Hi Brystonuser! ;)
For SCs :
Prince > King - Increase girth diameter in middle, also thicker at termination ends.
King > Emperor Crown - Similar girth, slightly thicker stiffer w/tighter twists at ends.
Emperor Crown > Double Crown - Visually similar perhaps only a 'tad' thicker at ends.

For ICs :
Compass Lake > Empress Crown > Empress Double Crown - All look fairly similar. Difference being only the model designation/names at their respective bullet plugs.

PCs :
Ruby Hill II > Ruby Mountain II - Definite step up in girth size at middle, as well~ends.
Ruby Mountain II > Ruby Double Crown - Again, visually similar, Ruby DC comes standard with Furutech F50 plugs. While Ruby M uses Wattgate, w/upgrade option to factory retrofit (+surcharge) same top Furutech carbon ones.

Have you tried/decided on any yet? I bet it will complement your Brystons very nicely.. But still best to request from your dealer a full loom loaner first to decide if they are really for you. For these money, choose and buy right, try to avoid/minimize any possibility of co$tly buyer's remorse later on. Goodluck.

I couldn't help you with clarifying the gauge of the cables you listed Bryston, suffice to say the new Siltech G7 cables are excellent cables imho & are built to last. Of the cables you mentioned, I use Siltech 330i rca's with my Oppo 103 dvd player and they have terrific resolution and tonal balance.

Of the cables you mentioned, the cables I would be happy to have in my system would be the Siltech King sc's & Ruby Mountain II pc's, though if it were me i'd spring for the Ruby Double Crown pc's.

Thanks for the responses.

Since my setup is used for both home theater and music with the inevitable increased distance between gear and speakers due to having a center channel speaker and tv in the middle I have to accommodate an unavoidable lengthy cable setup. Going Royal Signature all around is out of the question due to the expense it would cost for the long interconnect run thus my interest in how the Classic's compare to the Signatures in gauge.

My L/R amps are monos and will be placed by the speakers. This actually works out well because the speaker cables are more money than the interconnects per meter so I can get really short SC runs if Siltech offer that. I've only ever come across prices for 2.0M as the shortest length though in price sheets which has me a bit concerned.

So I only need 1.0M to 1.25M for my L/R SC's. I will need like 4.0M though for my L/R IC. What I'm currently considering is possibly doing Prince SC and maybe 770L IC but at 4.0M I know 770's are going to be very pricey. I'm thinking of going with the Golden Ridge II with XLR for my AES/EBU cable. Power cables would either be SPX-800 or Ruby Hill II as I'm not sure I could afford/justify the price of the Ruby Mountain II considering I would be looking at adding multiple cables.

Looking at the Siltech website I see just a few models list Furutech as an available option. Do you know if that is set in stone? I would prefer to have Furutech connectors on all Royal Signature cables I would buy.

I haven't brought any home to test yet. I would like to be able to try both the dealers 330L and 770L. Since the IC's he has are RCA and I don't want to recalibrate my system just to test them as I run all XLR to my amps now so I think I'll try the 330i's and 770's he has between my source and pre as I run RCA there currently. He also has the HF but I don't yet have my digital music player so have nothing to test out the digital cable with. I won't be able to test any power cables or any Signature items as he doesn't stock them, all have to be special ordered.
