Hi all, I have a pair of Synergy series F-30 Klipsh tower speakers, coupled with a Klipsh SW-112 (12" powered sub-woofer). They're all connected to my Onkyo TX-8050 Receiver. https://intl.onkyo-av.com/tx-8050 The speakers all sound great still, but the Onkyo's volume control knob is not working anymore, so we can only control the volume from the Onkyo remote. Also, sometimes the left channel disappears and I have to power-cycle the Onkyo to get it all to work again. We've had the Onkyo receiver, and Klipsch speakers almost 10 years now. (it's not the wiring, 'cause I double checked that and all is secure and tight). Anyway, I have a two-part questions below; 1./ Regarding my Klipsch (powered) subwoofer, I noticed even when everything is turned off, that the (powered) subwoofer still uses ~3.5 Watts from the wall.? Is this normal, or the fact that it is a "powered" subwoofer it will stay on waiting for a signal. ? 2./ any recommendations for a new'ish receiver.? - Marantz NR1200 (75W/ch@6ohms) - Dennon DRA-800H or 900H (100W/ch@8ohms) - ... ? The must have for us is that the receiver: -must have a built-in USB input dac, (for connecting flash-drive or 1-TB portable storage) so as to play all our mp3 and flac, wav, files, ... 96khz/24bit, and 192khz/24bit, and DSD, ... AND it must have the ability to play them in a random/shuffle format as well. Also, it must be able to play shuffle/random files controlled from the Remote and/or Receiver, and NOT need a TV connected to it. -must have subwoofer (pre-out). Having HDMI maybe a bonus feature, but we're not interested in having the TV on while listening to music, old-school I guess. I'm not interested in any 5.1/7.1/... avr surround sound systems, since all of our 5.1 audio files have been converted/mixed down to 2.1(Stereo). However, some friends have said that I could just get a good quality AVR Receiver, and just use it in Stereo mode, which is fine as long as it can deliver the power cleanly to my Klipsch's.
