CAT SL1 vs Modwright LS 36.5

Don't agree with Rfogel18 at all. The CAT is in another league to most all preamps out there. To bring it up several notches, tube rolling is what I found to really make it sing. IMHO, the Modwright isn't in the same league at all vs. the CAT. Add some NOS Mullards to the CAT and again IMHO, neither is the MP-1.
As they say, the CAT rules.

Jwm, I have heard the MP-1 on several occasions. IF you like a more diffuse and colored presentation, then yes, I would agree with you. OTOH,IF you prefer accuracy to source and a more dynamic presentation, then the CAT is IMO better. BTW, my ears are just fine, how are yours?
Clarrie, IMHO, the CAT would give you a great deal of pleasure and you won't go wrong with it.

Charles1dad, you say that the CAT is "good and depending on system
make up and matching can sound very good". What systems and match-
ups have you heard it in? Sounds like not even close to what it can actually do.
Plus you say the CAT has a lean tonality, can be forward and more
aggressive..You sure you've listened to a CAT??
Not any CAT that I have ever heard!

Rfogel8 and Charles1dad, when it comes to the CAT preamp, all I can say is clearly YMMV. I stand by what I said about the MP-1 ( which was a fairly recent version)...BTW, are you guys using anything BUT digital as the front end, because IF you are not, that would explain a lot!

Clarrie, just to complete my thoughts on this thread, I would HIGHLY recommend that you listen for yourself to the CAT and any other preamp you are considering. Preferably in your own system. Clearly, my experience and the other posters on this thread differs. I suspect that IF you were to ask ten a'philes what they thought of the differences between the preamps mentioned, you would get eleven different responses. Charles1dad is a Coincident fanboy, good for him, BUT I have heard almost all of their gear, and it does absolutely nothing for me. Use your ears and your own judgement and IMHO, that is the way to audio enlightenment.

Bombaywalla, try tube rolling into the phono stage..I know it's pricey, BUT I think you'll really like it, I know I did. BIG gains in overall imaging, better top to bottom coherence, more air on top and a lot more foundation in the bottom end.
Like I said before, i don't know what the other posters were hearing, BUT it sure doesn't sound anything like my CAT. Something definitely WAS NOT RIGHT in their systems.
