Thiel Owners

Jafant - The amps have been struggling for over a year and are indeed back home in fine fittle. The first tech made a mess of it, changing some cap values, mis-regulating and stressing some circuits. The second outfit came highly recommended as a warranty repair center for McIntosh among others. But their senior tech who could make sense of the mess was out for extended medical leave; and on return was buried in urgent backlog work. BUT, he went through both amps and got everything into synchronicity and they do sound good.

So, the DR-6 and 9s are like new, which is really quite good. My comparisons are the class A Benchmark AHB-2s and the Adcom GFA555II which I bought for entry level benchmarking. The Adcom really trails far behind in all audiophile ways, even though fairly well regarded in its time. The Classe and Benchmark are remarkably similar. I don't hear the "darkness" often attributed to the Classe. However I do hear a bit of gritty, dry hashiness in the Adcom (also repaired and tested as good.)
Now with 4 bridged amps / 8 channels available, I can make real time comparisons with 4 speakers under test - what joy. I'll get to some progress reports when the legal matters are finalized.

It is imperative to post both negative and positive experiences when dealing with these repair operations/techs.  We would not want other Audiophiles to have the same misfortune(s). 

I am looking forward in reading more about the Adcom/Benchmark/Classe'
shoot-outs.
Happy Listening!

I noticed 2 different sets of Thiel speakers available on USAudioMart ,
a pair of CS3.6s and 7.2s .

Also I would like to clarify my last post ,
I was trying to point out that a Reviewer was using a pair of
CS3.7 speakers as his reference , he had also owned a pair of 7.2s .
I looked up other reviews from this site and found SCS4Ts  and
CS3.7s were reviewed .
The reviewer of the 3.7s previously owned CS3.6s ,
this seems to be a Thiel freindly and knowledgable site .

As for my McCormack DNA-250 amp made by Conrad Johnson ,
I can not reccomend it in it's stock form but 
after upgrading componets trying to imitate the CJ MF-2550se 
I am amazed at the transformation and will say 
if you can afford the MF-2550SE go for it and it's not that heavy .
I can see why DNA owners rave about thier amps AFTER 
sending them in for upgrades and why CJ owners like their amps because of the custom Capacitors they use ( and won't sell me ) ,

Nice catch!  No doubt that the CJ MF-2550/2550SE will become a modern classic. This is probably the last solid-state power amp we will see from CJ as well. Thank You for posting impressions on this model plus McCormack DNA.
Happy Listening!

It seems that I found here in Italy a specialist in repairing even such sophisticated drivers like the customized Vifa for Thiel. Actually he is a highly rated amplifiers and loudspeakers craftsman builder and his lab is provided of all needed professional euipment to do it right. As I already told here, I already bought a full set of drivers for my CS3.6's from Rob Gillum but the defective ones are still in my hands and I would be very happy to have the possibility to get them properly working again as new spares. Next week I'll give him two mids and two woofers to try the reparation., he told me to have some idea on what can be the cause of the defective sound (mine were not fully die but shown only a sort of break up transient at certain frequency). I will report here the result of this attempted ressurrection in case someone is on the need.
