OK, but even the VT-150 has its limits at 60 watts/channel if you like 90 or 100+ dB listening volumes and end up with inefficient speakers or some that are current hogs. I'm old-school, but believe in settling on speakers before deciding on an amp.
But, back to LSA tube amps, they are good. I like my VT-70 and wouldn't hesitate to buy any of their other units.
