I recently scored a good deal on another modern monster receiver, the Onkyo SR875. 160W@8ohms, and it has a bloody massive toroidal transformer at the front:
The transformer itself has got to weigh 40 pounds, let alone the rest of the receiver also being pretty tanky.
I took some DC offset measurements yesterday to see what kind of shape it's in, across all 7 channels the highest offset was 15mV. So, it may be 15 years old, but it still measures basically like new. *chef's kiss*
Hooked up my HE6se V2 via a speaker-tap-to-4-pin-XLR adapter I made, did some quick testing, sounds tremendous. Pretty much the only complaint I've ever heard about this receiver is that it tends to run very hot, but that might be if you're powering all 7 channels. Powering just two channels, temps were typical for me.
Excited to put this head-to-head against my other monster Onkyo, the NR727. The DC offset on my NR727 is more like 50mV, which isn't bad, but it's not 15mV, so I may keep the 875 and sell the 727 on that basis alone.
Either way, both of these receivers only cost me about $150 each, so they're phenomenal ways to power the HE6se V2 for cheap.
Ultimately, I'd love to pick up a good vintage receiver from the days of the wattage wars, namely I've got my eyes on getting a Luxman R-117 if I can find one recently restored for a good price. But until then, either one of these two monster Onkyos will do juuuuuuuuuust fine. And I wouldn't be surprised if the value on these shoots up as they age into "vintage" status, as well. Just good ol' brute-force audio.
