Rowland 8ti or Krell FPB600c

My system consists of model 2 amp, Bat Vk-30Se pre amp, Wadia 860X, Transparent Super XLR int + spk wires 3 Richard G, Harmonic Tech PRO AC-11 power cords, Power Snakes Cobra on the 860X. WOW! What an upgrade for my 860X.

I had HT cable on my wadia(good),switched to Mamba(light years better). i put the HT on the amp-did'nt work! Everything got kinda dark and a little muddy. I'd try another cord on your amp. I'd also try Analysis Plus speaker cable.

What is a good power cord for my Jeff Rowland model 2 power amp?

Only upgrade from a Rowland 8Ti would be to either add a battery pack or go for broke and get the Model 9Ti's. The 9's will add more width and depth to the soundstage, plus a lot more slam! Go for it! I did.

I suggest you put another Cobra or Custom Power Cord Company instead of HT,then replace Transparent cables with Cardas Golden Cross or Golden Reference(Rowland uses Cardas wires,I guess),after that replace your preamp. with Rowland,and only then think about better Rowlands and battery packs.By the way,you didn't tell us what speakers you use.I envy you anyway,Rowlands are so good.Any of them.
