Jeff Rowland Pre-Amps: The Corus & The Capri

And the fouth approach would be to get Rowland Corus and 625, and get rid of what you have now beginning with those Cardas cables. I would first try Purist Audio, Gabriel Gold, Jorma and Stealth cables. In any case, I would probably play with cables and power cords to begin with before making big moves.

Well, never mind then. But if you change your equipment the situation might be different and without trying other brands you wouldn't know. You don't build your system around cables.
Tell us what you decide to do.

Yes, it's a difficult decision. I would guess that you are more attached to Pass amp than to Capri preamp. In any case, whatever you do will be an upgrade. Unless your speakers really need more current and power, I would probably get Rowland preamp now and later think about upgrading the rest of the electronics. After all, preamp is at the center of the system.

Cables are very important. And power cords. There are better, much better cables for your system and your room. Probably more expensive too but not necessarilly. Please give it a thought especially since you intend to upgrade.

Of course. However, the connections between the components should not be underestimated. Power cords can make a big difference too, the degree of it varies. When I put Custom Power Cord Co. Top Gun on my Audiolab integrated the improvement was incredible. No, it didn't start sounding like Rowland. There was already good power cord there before, by the way. Now I have a much better integrated but I didn't compare power cords yet, I just put the same Top Gun and it works great.
