Thiel Owners

At Coherent Source Service, they were effortless and pure. Rob had a great amp driving them, but I don't remember what it was. The flat-front drivers of the original 7 address a real problem of cone drivers. The sound of the upper driver falls into the cone cavity of the driver(s) beneath, creating a particular hollow congestion which I have identified both sonically and in measurements. The 7 is free from that problem. Even though Jim improved the technical driver performance for the 7.2, Rob and I both found the 7s more musically enjoyable in his small room where we could barely get 8' away.

I am told that Jim was working on the 7.3 after the 3.7, including a refinement of the 3.7/2.7 upper coax, modified to more readily cross over to the 6.5" CS7 lower midrange and CS2.7 -  8" woofer. The 7.3 would certainly have had the flat-star lower drivers, which address that cone cavity problem. Plus each generation of his drivers stood on the shoulders of its predecessors. Imagine that speaker. But, the 7s or 7.2s are pretty good in their own right. If a pair came my way, I could live with either one of them.

Well I’m gonna see if I can trade for the 7’s or not for the hell of it. Whether I’ll go through or not. I dunno cause I know I wouldn’t be able to afford an amp afterwards for a bit lol

Thank You for the follow up to thoft's query about the 7 Series loudspeakers. I agree in that a 7.3 model would have been a game-changer. 

Happy Listening!

So I am gonna be getting a pair of classe model 25’s. Guy used them on apogee speakers. I am excited to see what this will bring. He is letting me do a payment plan.

^Nice amps for Thiels. Unusually most users report better results through the single ended RCA inputs rather the balanced XLR inputs with these amps. I’d caution you about using these amps in bridged mono configuration with your Thiel’s. Typically bridged amps don’t do well into low impedances. A better alternative would be to have your Thiel’s modified so that each would have dual binding post pairs and have each amp run a channel to the each of the binding posts of each speaker. In this configuration each amp would receive either two left channel or two right channel inputs respectively. A pre with dual stereo pre outs helps facilitate this. I would suggest avoiding a pre that leans to the dark side or has a rolled off treble with these amps, “liquid” presentation would be a plus. These are fairly sensitive amps, be careful of very high output pres, or you might have limited volume control range.
