That was impressive. A video vs written subjective review comes across as being much more convincing, the descriptive attributes of the component seem to have more meaning when conveyed with that pointed and matter of fact way he has.
Luckily, the background noise level in my room is about 10db higher than his so, the additional resolution from the cubed series vs an SST won't do me any good, (I think 24db is at the threshold of normal human auditory limits).
At $6K vs the 3 or 4 a 3B used to cost making a purchase decision based on performance only is complicated by personal and economic factors these days, not to mention the price/value competition of other technologies.
The best thing about the review is, if I remember correctly, that he managed to get through it without once saying 'inky blacks'. That says alot about his credibility as far as I'm concerned. Still, a nice looking amp and now no reason for so-called expert listeners to spend $20K and more for something no better by any metric.
