Infinity IRS Sigma for 2K...Should I do it??

Hello Danheather:

The IRS Epsilon, Sigma, Delta were the last real High-end speakers Infinity made. The newer stuff is good, but lacking the planar implementations. I own IRS Beta, and love them, so I may be a bit biased, however I also have another system with Aerial 10t's. Love 'em both, but they are two different means to the same end.

One concern is replacement parts, if you purchase the Sigma, parts are still available from Infinity which is a good thing. I feel that you should go for it, I've heard both the Epsilon and the Sigma, and liked them both. You do not say where you are located, as there is a pair of Epsilons listed here for $2600, needing local pickup in Arizona. If you were close to those, it would be an even better deal IMHO, with the advantages of the Epsilon's use of the servo feedback woofer as well as the LEMIM planar midrange driver. The drawback here is the Epsilons require bi-amping, where the Sigma's do not. Best of luck to you regardless of your final decision, please post and let us know what you do buy, and your thoughts.

Thanks Beemer. I saw Epsilons too. I'm in California. My only major concern is with regard to power. They're going to be in a relatively small room so I don't think they'd need a TON of power, but what would you say is the minimum requirement??

Thanks again,

Dan

The Sigma tech sheet I have states 87db at 1 watt/meter.
Not the highest in efficiency. A good amp 150w/channel+ with high current reserves would probably be best. Plinius comes to mind as a good choice, as would be Classe. If these were a tad more efficient, I'd tell ya to try the Gamut D-200, which, IMHO is a really great sounding amp, however it is current limited. On my 10t's there was a problem with woofer control, although the midrange from the Gamut was spectacular!
