Infinity Irs Beta


I recently purchased a set of the Irs Betas. My system consists of a Krell Kct Preamp, Krell Kps28 CD player, Krell Fpb400 cx which I am powering the mid,high panels and using the cast interconnects between them and a Krell Ksa300 for the bass towers with the servo unit. Would tubes on the top end be a big improvement? Any folks here run tubes on their Betas and have you compared the two? It sounds wonderful as is.

I also had the LS 25mk2 (the best-not the Mk3). Wonderful. I think this would be fine.
Rvito, The ARC VT100 (mk2) sounded quite good. I only went to the Hurricanes for more power (which I really didn't need). Remember I listen at a lower lever then most (most of the time). The ARC had more of the warmer tube sound (but not of the early 70's). A GREAT amp if you can get it and I also understand the MK2 is better then the MK3.

So good to see Sirspeedy back in the rooms commenting again! Yes the IRS Beta's are a fine (great?!) speaker. I have the model before that one (The Infinity RS-1B's). I agree with all the comments above. Tubes on top/SS on bottom. I have used Audio Research VT 100 and Hurricanes on the top and now MacIntosch MC 275 (2 of them in mono @ 150watts per).

What's the size room and at what level do you listen? Also, do you prefer classical (large, dramatic or small)to other types of music? I love classical and at most times the VT100 was spot on.

Rvito, your room is considered (by me at least) moderate to large. Mine is about the same size. I had no problem driving the top end of the RS-1B's with the ARC VT100mk2. You should be fine with them. What other amps were you considering?

Mark, great hearing from you!! My e-mail is rick.daversa@gmail.com. Perhaps (if you are still in the tri-state area) we can catch up again. Hope Sid is ok?
Peace!

P.S. Correct about the tweeter and the tape (or a small plate). I did that to my tweeters.
