A $600 electrostat? That's way too cheap to be considered high end. In fact, it is only 30.85% as good as an LCD-3. Now, if Koss raised the price by a couple thousand, I might consider it. Until then, I'd much rather listen to [note to self: insert name of some mediocre overpriced headphone that people rave over because it is really expensive.]
I think a 35 mm machined billet front panel on the energizer/amp would improve them also.... They should also claim that all the unobtainium used is six nines pure (99.9999 %)*
*As far as I know, doing a QC assay on "six nines" copper is beyond the abilities of all but a few highly-specialized research labs in the world. I defy ANY audio cable manufacturer to show me that they are doing NIST-traceable purity assays to prove that all incoming lots of copper wire they use in their cables is truly "six nines OFC." Also, although some cable manufacturers specify they use "six nines silver" - I do not believe that silver of this purity level is available at all on the market, at any price. It would have to be special made - IF it is even possible- and I don't think that there is even one high-end cable manufacturer out there who is refining his own metal and drawing his own wire. In my opinion the only thing that is "six nines" purity in these products is the ultra-pure B.S. used in their marketing.
So refreshing to finally read someone cutting thru the BS so prevalent around the topic of cables. +1
