Mendelssohn violin concerto op.64 with Heifetz. Simply,a work of art !

As far as I can tell S'phile has not yet reviewed any cables from DH Labs. I've had a fair amount of exposure to mid priced IC's ($150-$600) from Tara, XLO, Kimber, AZ, Analysis Plus, MIT, Shunyata, as well as some DIY and internet only brands and I keep coming back to DH labs cables as my reference. The best way I can describe them is "honest" and I think they represent great value. I think your readers would appreciate reading about them. I think it would also provide a needed counerbalance to the recent Tara labs review.

I'm a tube guy. I run a tubed CD player (Musical Fidelity A5) or tubed phono stage (BAT VK-P5) through a tubed pre-amp (BAT VK-3i) into an 80-wpc power amp (Sonic Frontiers SFS-80). I'm driving Thiel 2.2 speakers which really need and can handle a lot more power but I'm not complaining about the sound. If I step up to a more powerful solid state amp (perhaps a BAT VK-220 at 125 wpc) but keep the rest of the tubed chain intact will I lose the tubed sound that I love? Or more generally, how much of that tubed sound is a function of the power amp?
