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.

Why the middle name is IRS?

Back in the day, Infinity made a series of high-end speakers called The Infinity Reference Standard, (IRS) series.

These include:

The IRS
The IRS Beta
The IRS Delta
The IRS Gamma
The IRS Epsilon
The IRS Omega
The IRS Sigma

So really, the name the OP uses is correct. I was an Infinity dealer for many years and even sold a few of each of the above, except for the IRS.

Out of the hundreds and hundreds and hundreds of speakers that I have personally owned, the Beta's are still the one speaker I wish I never had sold. Still one of the best speaker systems ever made....IMHO.

I used to own them...Awesome speakers! And I mean great!! The bad news is they might sound fine now,but will definitely sound better with a good(relatively powerful) tube amp on the panels....I ran top quality Audio research units on mine.You definitely want solid state on those bass towers though.that's where the Krells should go,which is what I was using on mine....Good luck.
