For one thing, Kevin at Upscale is not a terrific dealer guy. He may have a few buddies out there, but I know from personal experience that he doesn't know what he's talking about. David Lewis is the same way. AS FOR YOUR SILWAY MK-2: I've tried some extensively, comparing it to many others, and find that it lacks natural timbre in the upper midrange, and sounds laid back in that range; gives the music an artificially "crystalline" quality. Transient snap in the treble seems a little hyped also, however smooth it is. Bass is very dynamic. If that's what you need to get neutral sound for your system, then I doubt there's anything better out there anywhere near the price. But in my system, whether on headphones and a tube headphone amp, or on a solid state linestage with Krell power amp (and either from vinyl or CD), THE MIT 330 SHOTGUN HAS BEATEN EVERY INTERCONNECT I'VE TRIED UNDER $3000 PER METER...and this is only a $700 interconnect!! GOOD LUCK GETTING TUBES TO GO QUIETER. What solid state preamp convinced you to get into tubes? I'm open minded about tube preamps, but not all solid state ones are cut from the same cloth...All the best.
