As I said before, the Thiel's are great speakers. If you value soundstage, timbral accuracy, overall clarity, and value, then this is definitely a top choice.
If you have the opportunity to listen to the Avalon Indra before your purchase, that would be one last speaker to consider. The driver integration is more cohesive and refined on the Avalon. I went from Thiel to Avalon, and it is a very logical progression.
Also, don't rule-out a tubed preamp to go with your amp.
Finally, I would recommend you get some inexpensive cables to start. When the speakers are broken-in, demo several cables to fine-tune the sound. Cables are not a band-aid; they are the icing. Cables are very system and user dependent. You've learned that reviews are a guide and not the answer, so don't get caught-up in marketing concepts. Always use your ears when investing significant money.
