Infinity Epsilon/ Beta speakers-- Classsics???

I've got to go along with Jvogt, the RS1x series were quite good as well and a really silly bargain today. They're not perfect but damn close for the money. I've got to laugh today at the "dumbing down" of High-End. Case in point: Totem, sure, the little critters sound good, but most of these folks chasing the dream have never experienced a true full-range speaker, and never will at today's pricing. The big vintage Infinity RS1x and Beta not only gave you the music, but the excitement as well.
Have you ever been in a large church or hall with a pipe organ? If you have I'm sure you can relate to the feeling in your chest of the movement of air around the lower fundamentals. My Betas can reproduce that "charged air" in my living room with ease. Show me another speaker available used at around $5000 that will do the same!

First, many thanks to those who responded. In my original post on this thread, I meant to ask about the newer model Sigma(vintage 1997) and how it compared to the Epsilon, or other high end speakers of today. I never was a big fan of Infinity speakers, but these models seem to be much different. Therefore, any one familiar with the sound quality of the Sigma; because, I could not find any reviews on the net about them. Thank you!

The IRS Betas are hard to beat, and at the price they sell for used, giant killers. I agree that ARC tubes for the panels are a no-brainer, as they were built and tuned with these electronics. They need a big room, lots of watts and quality components in font of them. I have had them for 5 years or so and have no interest in replacing them (upgrading is now focusing on front end components).
See http://www.audiophilia.com/features/tm1.htm for thoughts on appropriate room considerations for these speakers.

Right on Beemer!!!
I have heard the Epsilon and they do NOT compare to the Batas or the RS 1-B's......I have the 1-B's and with the proper equipment tubed top and SS amp on bottom and a good source (I use vinyl)..they will sing and sling!

I came home form the NYC show two weeks ago very impressed with the speakers (the set ups) I heard (Wilson, Dynaudio, Innersound, Pipes etc).....BUT I was most impressed that after listening to my RS 1-b's later that night at home they sounded just as good(and better) then many of the rest.

I am sure you will do well with the Betas!

The best of luck!

Hello, I am also an Infinity enthusiast and have a pair of Renaissance 90's that I absolutely LOVE- they are SUPERB speakers!!! If you look around and can find a pair for approx $1500, they would be a Great buy. Have you seen the site: www.bobbsyhred.com/infinity.html ?? I also very much admire the Quantum & Q models Infinity made back in the late 70's- I have a pair of Quantum 3's, Qb's and Qe's and they are all great as well. Also- the whole thing about power can be a bit exagerated- well, as far as the Ren 90's go anyway. I am also a vintage Sansui enthusiast (www.classicsansui.com) -> I have quite a few Sansui amps & receivers in my collection- and all of them can drive the Ren 90's - JUST FINE. I had a new Odyssey Stratos amp (www.odysseyaudio.com) and sold it- it was nice and all- but didnt offer anything more than the Sansui hi fi gear I already have.
