Masi:
I have owned the Prima Luna Prologue Two (integrated amp) for 10 months and the Prologue Five (power amp) for 5 months. After about 3 months, I replaced the stock tubes on the Prologue Two with Svetlana K88's; NOS Sylvania 12AX7's; and NOS Mullard 12AU7's. What prompted the purchase is that one of the stock tubes burned out and I figured that it was a good idea to have a spare set. I purchased the tubes from Upscale Audio (where I purchased the amps). I am still using the stock tubes that came with the Prologue Five.
For both amps, I am using IXOS Silver Gamma 1001 interconnects (silver/copper hybrid); Signal Cable Classic Speaker Cables; and Cardas TP5 power cords. I have used these assorted cables in a variety of systems over the last 4 years. I like the way silver/copper hybrid interconnects sound ... good detail with pleasing bass and treble. Additionally, I also like the sound of Better Cables and Signal Cable Silver interconnects with these amps.
Changing the tubes has made for a more elegant, smoother, and more refined sound. The stock tubes were more than OK, but the new tubes really brought the amp up a notch. If you have the extra $200 to $300 burning the proverbial hole, try a new set of tubes.
