Hands down the best receiver I've ever owned. Nothing I've bought since laying down the $150 for it (money very well spent) has come close to the loudness and clarity of sound this beast has. Unfortunately a power transistor on the left channel blew and I need to find a replacement now. - 10/10 by ChrisOG
I have had this SA-700 since I bought it new in 1978 to power Syngergistics S-72A towers (two). I just got myself the FiiO D3 Digital to Analog Audio Converter - 192kHz/24bit Optical and Coaxial DAC (Amazon, $29.98) and a 25-foot optical cable (L-com Digital Audio Optical TOSLink Cable Optic 25 feet, Amazon, $3.79 + Toslink Female to Mini-Plug Male Adapter (also made by L-com, Amazon, $2.52). I connected the mini-plug end to my 9,1iMac (early 2009 24 3.06 MHz/ATI Radeon 4850 build-to-order, with 8 GB RAM and 1TB HD; it has a digital audio out in the same physical jack as the analog headphone jack, and it auto-senses what to output, disabling volume control; all iMacs do since then or a year earlier). The sound I got is exceptionally fine when playing FLAC that is of good quality (Dido, _Life for Rent_). I am sending back my unopened refurbished Onkyo A/C receiver, TX-NR515, back to Onkyo, and getting back my $248.16 (a very good price, but still). It could not possibly deliver better power/sound to my Synergistics (they are 4 ohm-rated; the Onkyo wants 6-ohm at minimum) than my 2009 iMac/1978 Technics SA-700/optical-DAC-RCA plugs combination. :) - 10/10 by mareklug
