best speaker?

I can't say about the rest of your choices however, the maggies won't work well with your amp, not enough power.

Well, looking at your equipment, the Revels would obviously work well, since they were designed with Levinson equipment in mind.

However, if you are considering the Maggies, you should determine the type of speaker you really want. There is a big difference in sound between the planer types (Maggie, Martin Logan, etc..) and the standard dynamic speakers (Revels, JM labs, etc...).

I suggest that you go and listen at a dealer and determine the type of speaker you like. (Once you buy speakers, it is difficult to sell them, since shipping them is a big pain in the butt!)

PS I own the Studios and love them. I also use a Mark Levinson No. 23 amp, along with a Solid state Ayre K-1x preamp, so they work well with an all solid state system.
(Although, I know many others use tube equipment with them as well.)

PPS I used to own the Martin Logan Sequel IIs, with a Levinson amp, and I really enjoyed them for many years, so I know that planer (and electrostatic), type of speakers have their own charms!

Thanx guys.

Let me clear some stuff up:

Mark Levinson and Revel is a Pathetic combination, etched and dry, unless you like audio special effects over music then steer clear of Revel. And the Revels are not built on Levinson equipment at all. Remember Kurt's amplifer is 10 years pre-Revel and has little more than the same name on them in common. Your 331 sounds nothing like a No. 23 and is nearly 1/3rd the power. I would recommend getting a No. 23 or 23.5 if you desire the Revels. Your 331 cannot hold a candle to them in this application.

Your best bet with a thread like this is suggest what it is you want to upgrade about your Thiel 3.6's. Some of the speakers you suggest are very similar to the Thiels you own and may not be a worthwhile upgrade in your own opinion. Plus what price range are you really in $6000 or $12,000?

Tire guy is right about your amp which won't work from a power stand point with any speaker you chose except the JMLab which will likely give you an ill matched tonal balance to the bright side. .

If you have the space you might want to add Dunlavy speakers to your list. The company is out-of-business, which makes these remarkable speakers that much more of a bargain on the high-end market.
