Thiel CS6

Alan,

Actually, I would caution the use of X250 and recommend going with the X250.5. Prior to my current speakers, Verity Parsifal Encore, I had the Thiel 2.2 and then 3.6 for many years. I was driving the 3.6 with a Mark Levinson 333. When it died, I replaced it with a Pass X350.5. I had been thinking about replacing the Thiels for a while at that time, but the Pass 350.5 brought new revelations about the Thiel 3.6 that I had never heard before. And I was sure that I had pushed them to the limit with my previous setup. It made me reconsider keeping the Thiels for few more years.

Few months before I purchased mine, I had a privilege to listen to a side-by-side comparison of X-350 and X-350.5 at a friend's house driving a pair of Avalons. The X-350 sounded like a typical SS that people complained about, cold, sterile, and unimvolving. We were all surprised that it was very out of character of what we wouldexpect from Nelson Pass. But the X-350.5 was very different. It retained all the good stuff of the X-350, but brought back the midrange warmth that Pass was famous for. We all felt the difference warranted more than a ".5" upgrade designation.

Hi Steve, Nelson and his crew worked on my Pass Labs X-250 for two weeks around 6 years ago. It was having a slight noise problem that was coming from the right channel. while working on it, and trying to solve the problem. The new circuitry that's used in the X-250.5 was developed. Boy I got lucky!You could say my amp was the prototype that became the X-250.5. Nelson even told me on the phone, that it was a much better amp then the X-350. So I'm sure it will be fine.
Crazy but true story Steve.

Hi, sorry about the delay. I haven't looked at this post in a while. My Thiels stand 9ft apart on centers. I have enjoyed my X-350 for 10 years now. I'd love to give the X350.5 a try. Maybe next year...

Hi Gundam91 and Tony Thanks for getting back to me as well.
Just so you know a little bit about myself. I've spent 40 years in Recording Studios, Master Labs and Record Companies.I've worked as a Composer/Lyrist/Vocalist & Assistant Engineer, on many projects in Los Angeles. I've been very lucky to work with great Musical Giants who where
Composers and Arrangers like Ray Ellis/Billie Holiday/Lady In Satin/ and so so much more that he did. His son Marc who's my best and we're still working on Projects today Who's done/The Movie Anchorman/ Master Of Disguise/and so much more. Another great friend of mine and another best friend that I miss. Jim Helms/The Kung Fu T.V. Series/ UFO Chronicals & 16 movie's of the week. Peter Anders Songwriter/and so on.. So I take this Music we all love very serious.
The Room that I have measures 18'L X 14' But opens up into my Dinning Area that is 13' L X 9' W
And the measurements that Mr Thiel has in his Manual is darn close to where I have the Eggleston Andra's. Only difference is that they're 8'.5" Center to center. In the manual it says 8' But because of the room opening up as it does, into the Dinning Area it could change.
On my review I will listen to Classical,Jazz,Rythum And Blues,Pop, Rock, Alternative, Music For Organ, Bass And Timpani and County that I've been writing with Marc ever since someone very BiG RIPPED US OFF on a Pop tune that was meant for Vanessa Williams back in 1990's.
Just to let you all know, I'm hoping that the Thiel's are the the ones I'm going to be living with for now! They're not so easy to move....

Correction on my Amp. It could of been 7 years that it was worked on . Boy does time fly...
