Infinity Epsilon/ Beta speakers-- Classsics???

Epsilons are still fairly recent and a good value used.
IRS Beta....I have a set and thus my opinion will be biased, however I feel a used set of Betas with the proper frontend will stand with almost any current "reference" speaker, at a fraction of the price. Good true full range speakers today are ridiculously overpriced IMHO.

The Betas can sound terrific. The best sound I got out of them was with ARC tubes on top and a QSC 3000Mx on the bottom. I used Cardas cables. Also had to refoam a woofer.

No experience with the Epsilons.

Good Luck!!

I owned a pair of Infinity RS-1b, the predecessor to the
Infinity Beta, and a friend owned a pair of Betas.

Yes, they are both classics. Each system has it's strengths
and weaknesses but on balance they are among the finest
of speakers EVER made. I sold my RS-1b's because I moved
and my present room is too small. Both systems are a
bargain on the used market, when they are available.

I can't speak to the Epsilons, I've never heard them.
