I agree, Thiel end is a real crime against the meaning that Tom Thiel expressed and summarized so well two posts above mine. I became a Thiel owner (cs 3.6) only around one year ago and love so much what I can hear, the whole Thiel's history, the unbelievable professional approach to every single detail of the project that to me doesn't matter if Thiel company is no more, doesn't matter if the genuine spare drivers start to be hard to find. Hard but not impossible, recently I bought a complete new set from Rob Gillum and due to the fact that I live in Italy it costed me also a big amount for the shipping and customs, but my aim is to preserve the soul of this wonderful loudspeaker as Jim and all his staff intended to be. It's a piece of artwork, not easy to replicate, who nowadys is able to offer this kind of knowledge? Which company do invest so much to develop custom drivers as Thiel did?(for this reason I bought a genuine full set as spare, because similar are not the same , specially with first order XO design). So, thank you America, americans, doing this. I also appreciate some our good italian loudspeakers maker, for sure ,excellence has no boundaries.
