It's truly a testament of the human spirit that we have a genuine, high-end tube manufacturer from the former Yugoslavia - Serbia, to be precise. Serbia's NAT Audio is quickly becoming recognized as a superb manufacturer of tube high-end gear, with quality and sonics right up there with the best, if not THE top! The amp pictured is of the SET monoblock (single ended) variety, basically heavenly tube sound that no solid state amplifier could ever hope to achieve. At 35w of SET power (careful now, don't think of these being measly solid state watt's; typically, an SET amp has more guts and glory than an equivalent solid state amp), you can run just about any decently sensitive speaker to gobs of volume and sonic bliss. Soon to be seen and heard in the US, price for 1 pair - $7000
