CAT SL-1 MK III vs. First Sound Presence DeLuxe

Frank,
this topic has come up several times now & member "Rayhall" has written extensively about it. Search the archives here @ Audiogon under his moniker 'rayhall' under Amps/Preamps.

Here are some links that I found for you:

here's is a link if you decide to get the CAT & want to tube roll. Or, this thread might tell you that you do not want a CAT since it sounds good only if you have hi-end NOS tubes! Interpret it the way you want!

FWIW. Apologies in advance if you have already read them

Tvad:

Interesting that you wrote that you found the First Sound lacks "sweetness." As soon as I read it, I knew exactly what you meant. I, too, have found that about the First Sound. In contrast, the CAT that I once owned (around 1992), never lacked for "sweetness," which, for me, means that ability to convey an emotion, be it poignant, tender, angry, eerie, etc. I have noticed this about the First Sound, and thought that perhaps I needed a change in components, but your comments ring true. As such, it seems a coloration that prevents music from being quite as "sweet" as it can be -- and as it is in real life. I've heard it with an Accuphase amp, Tetra speakers (where it actually managed to sound somewhat sweet), my Hurricanes, Musical Fidelity amps, but it's never quite moved me. Fascinatingly, I owned the original Presence pre-amp, which DID sound sweeter. It seems customary to assume that the newer version of a component will be superior, but I find myself at times wishing for my original First Sound, which, now that I think of it, also had a richer (not fatter, just more true-to-life) mid-bass. The current incarnation is "tighter" in the mid-bass, but somewhat to the point of leanness instead of lushness. Kind of like the difference between the WATT/Puppy 2s (sweeter) and the WATT/Puppy 3s. which were unquestionably leaner than the 2s.
Thanks for crystallizing my wistfulness about the First Sound into something more concrete.

The stock tubes are not sweet. If you want a touch of sweetness, tube roll to something like amperex.

Cheers.

In my Presence Deluxe II, I tube rolled Amperex 7308 PQ White Label USA, Amperex 6922 PQ White Label USA, Amperex Pinch Waist 6922 PQ White Label, Amperex Bugle Boy 6DJ8, Matsushita 6DJ8, Siemens 6922 "D" Getter 1959.

The preamp in my system was outstanding...but it was never sweet. I did not try Mullard, Telefunken, Valvo or Brimar tubes. One of those might have made a difference...

bombywalla: thanks for the very interesting links. I just wonder why some people tell me to stay away from the SL-1 MK III and go for a SL-1 Ultimate? Are the changes that dramatic?
