pre amp for Air Tight ATM3 monos.

I am looking for suggestions for a good quality preamp to go
with Air Tight ATM 3 monoblocks.My front end is Combak Harmonix,Speakers Avalon Arcus.Thks
How about a Klyne 7 LX ?
Has extra gain settings. Excellent sound.
my suggestion is to not use a separate preamp and simply use the volume controls on the Atm3s. While, my 3's have upgraded volume pots, I still have not been able to find a preamp which does not colour the sound of the 3s in a negative way.
