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

Frankpiet,
welcome!
That's strange! I cannot understand why people would tell you to "stay away" from a SL1 Sig Mk3?
In another thread 'sbank"/Spencer did quote you what Ken Stevens told him that a SL1 Sig Mk3 was the best value if you did not have the money for an Ultimake mk2.
The changes in the Ultimake mk2 are mostly to the power supply. It's more substantial than the SL1 Sig Mk3 hence the Ultimake mk2 dynamics are supposed to be better. NOte that the new product is improving upon something is very, very good already. Could you preceive the upgrade in sound? Your ears & system will be the judge.
Also, the Ultimake mk2 has some improvements so that the timbral accuracy is better than the SL1 Sig Mk3. These, I'm told, are the 2 major upgrades.
