PMC EB1i v. Thiel CS3.7 v. Pioneer S1-EX v. ???


I'm starting to look at speakers in the $10-16K range, new. These three are high on the list, along with used Vandie 5As. Tyler D20s and the new AZ Crescendos also interest me. Anyone have the chance to compare some or all of these fine speakers?

They'll be driven by Mac MC501 amps + C2300 pre. I listen mostly to '50s &'60s jazz, with some classic rock, bluegrass, and folk. 90% of the time I listen to vinyl on this rig. The room is 28x17x8, opening into hallways at both corners along the long wall behind the speakers (so no real bass issues in those corners). It's a hard room softened with 9 acoustic panels and two bass traps.

My listening priorities for this system are macro- and micro-dynamics, nuance, tonal purity, and realistic scale. I'd like the speakers to disappear while projecting a 3D soundstage and solid low frequency pressure into the room. (The Thiels would likely need a sub.) They'll also have to serve the 60-inch plasma TV on the wall 4 feet behind them in a 2-channel, pseudo-home theater set up. Not much to ask, I know.... :)

I can get a great local price on EB1is but I don't want the deal to make the call. Of course, I'll audition all of them eventually but it's impossible to find them all in one place--or even more than one. So I'd like to draw on the experience of this knowledgeable group as I make my way.

Thanks,
Bill

I've never listened to the MB2i but the size of your listening room would obviously be a consideration. I recently had a conversation with a PMC aficiondo who has owned and demoed a wide variety of PMC's. He indicated to me that his preference is the IB2i primarily due to the flat carbon piston driver versus the radial design used in the MB2i. The carbon piston driver is a real winner in his opinion creating very realistic well tuned bass.

Like the heat sink on the outside, the flat looking driver is largely a cosmetic effect which helps sell the speaker ("technology" one can "see" helps people to "hear"). Decades of research have proven that conical shaped drivers are the best shape for woofers - being both light and and having increased rigidity due to the shape.

Not to say that the PMC driver is not good because it is very good but overall it is striking visual effect more than anything else.
The striking visual effect of the flat bass driver is certainly more to the liking of my wife. And the bass it produces through the ATL really fills my room, which isn't easily done; it's quick and tuneful and digs down. I've come to really like these speakers. In fact, I just ordered a pair in cherry to beat the price increase that goes into effect on Friday. I'm excited! Thanks to all for your help.

Congratulations on the new speakers. The IB2i will most likely last you a lifetime. Great accomplished speakers.

Enjoy~

ps. similarly I am intimidated by the scary looking drivers of the MB2i.
