You must learn to take a lot of information with a grain of salt. Everyone has an opinion about everything. My best advice is to listen and judge for yourself if a particular speaker or whatever is good for YOU.
As for your original question, I don't think anything is wrong with Thiel speakers. They are time aligned and phase correct. A lot of thought and engineering has gone into the design. I have never owned Thiels but have listened to them many times. I settled on Vandersteen for my on personal reasons. They are also phase correct and time aligned. Thiels are well made speakers. Jim Thiel uses his own designs and does not source drivers from other sources. they must be set up correctly and are generally in need of good amplification.
I have tried many cables of all prices and finally settled on Harmonic Technology Pro Silway MK.II. Here again you need to try and Harmonic gives you a 30 day trial at which time you can return the cables for a refund from your dealer. For a silver cable, they sure are smooth without loss of detail. I personally like them better than the Nordost SPM line. The Silway retails for $399/1 meter or $250 for 1/2 meter. Not bad considering the performance.
I also like the Tara Labs ISM The 2. They are also very smooth and detailed. The 2 is more neutral than the cheaper Air 1 series. However, The 2 is a bit pricey as in $1395 for .6 meter.
