Audio Research Ref 5 and Krell amps

Mitch4,

I have had the Krell 450 mcx for a couple of years now. I think about replacing them with the newer EVO series but I am not sure if they are that much better. In the meantime, I am considering getting a new preamp.

microstrip & bifwynne,

Thanks for your feedback. I have always used ss preamps but after reading all the positive reviews on the ref 5, I thought I give tube preamp a chance. I am looking for a slightly larger soundstage and warmer sound that tube is suppose to provide.
Based on the high input impedance of the Krell, the Ref 5 should work well. I am planning to use balanced outputs.

Macdadtexas,
I will place an order the ref 5 in a couple of weeks.

So what is the preamp your using right now with the 450's? And have you tryed any of the Evo preamps or are you strickly headed in the tube direction for a change?

Heykay,

I am currently using a Pass Labs XP-10. I have always had SS preamps so I want to try tube for a change.

Sfstereo, I used to own an ARC Ref-3. I recently exchanged it for a Ref-5. I love my ARC gear, especially the Ref-3/5. Just for fun, I suggest you try to demo an ARC tube amp from a dealer or friend and match it up with the Ref-5. If you do, get ready for a real treat for the ears. The synergy is magical, which should be no surprise.

Two important caveats. First, I have read that a new Ref-5 has a long break-in-period; maybe 500 hours. So if you're inclined to see what the Ref-5 can do when hooked up to an ARC tube amp, be patient. Same holds true even if you pass on the ARC tube amp/Krell SS amp shootout. Don't judge the Ref until it breaks in.

FWIW, I see that a number of Ref 110 power amps are listed on A'gon. Try and use KT-120 tubes. If you want more power, ARC just released for your listening pleasure the new Ref 150, which replaces the Ref 110.

Second, as always, if you road test an ARC tube amp, be sure it will match well with your speakers.

That's about it. Good Luck!!

Not a dealer and no relationship to ARC. My gear is all ARC tube and I suppose I am prejudiced in favor of ARC.
