Peter Marcks obviously has the patience of a saint, 'cause he's had to listen to my bellyaching for days over at the Hsu forum!
No, I certainly don't use the amps of my receiver. I used to have a pair of Hsu 500 Watt amps running my pair of TN-1220's, but in the end it was more efficient to go with a 400 WPC stereo amp and the external EQ box, fed by my Behringer DSP-1124.
I'm obviously biased, but Hsu and his company reps have been pretty classy with regards to
The Company That Must Not Be Named! It's us "fanboys" that cause most of the problems.
As for the amp in the box, my objection to that is that I simply don't feel that's a good environment for an amp. It subjected to a lot of vibration and heat within a closed air space. Yeah, I know the amps are well made, and being digital they should run cool. Yet the warranty is still 7 years on the driver and 2 on the electronics...I've never had any external amp crap out on me in less than a decade. Not that it'll
never happen, it just hasn't yet.
I love the cylinder form, and I've come to believe it has a lot of advantages over a box. More even than that, I simply prefer the flexibility and durability of running my subs of an external amp. I don't plan to ever use a powered sub again, at least not in my Big Rig. It would be fine in my 2nd rig, where it doesn't get used as much nor get played very loudly.
Peter made the tantelizing suggestion that perhaps a passive version of the VTF-HO 3 could be made. If so, I'll retract 90% of my ranting (I still dig the tube...). I'd be very interested if that gets the green light.
Overall I guess I'll get over it. I guess mostly I just wanted to complain a little more first!
