(I could really use some serious help here folks, rather befuddled right now) ...To drive the PSB Stratus Series. I'm looking to purchase a solid receiver that will be versatile with regards to adding seperate amps at a later date, but will be sufficient solo until then for solid/clean performance. (running 5.1 silveris, C6 and mini's) The main issue here is that the speakers are 4 ohm speakers, and after spending hours reading spec sheets, I can't seem to find a receiver rated specifically down to 4 ohm loads. All I seem to see are the industry standard 8 ohm, and the usual 'sales pitch' rating at 6 ohms, in order enable exaggerated power ratings on sales/promo sheets. One rather large fear I have about the purchase of a new receiver is the possible distortion I might get with my 4 ohm speakers. example: an amp might have .05 %THD at 8ohms, then .7 %thd at 6 ohms. Now that's a major magnitude(4x?) of distortion increase just going from 8 to 6 ohms. I don't have my sceintific calculater handy(wouldn't know how to derive it anywho) but I hesitate to think about the THD for most amps when driving 4 ohm speakers. guessing if we go another 4x, I'd be looking at a a crazy distortion of about 10 %THD??? Talk about scarey, and I hope I'm completely wrong. I hope more informed people out there than myself can spare a few minutes to jump in and educate me on how best to proceed from here.
