It would be smooth machine but I fear the worst with HK as the last several years their products have been plagued with problems. I have a friend who falls for their marketing all the time, for example he boosts about the size of the transformer in his 7000 being bigger than any reciever he's seen and most amplifiers. What I can't tell him is that the casing over it is probably oversized as it is only a 500 VA transformer, most mi-fi decent amps will have twice that. Also the size of the caps which are 22,000 each for a total of 44,000 of filter capacitance. Fine but not great and certainly not enough for the + or - 75 amp peak for any sustained time. Amps that claim to have a 30 amp peak have way better supplies than that and can drive 4 ohms load fine.
I do think they sound good but are scarey. Over 20 percent failure rate on the last years models.
