I am an old school "Audiophile" and these speakers have some of the best sound I have ever heard!
Use the Optical Input for best sound, if you can! And they have PLENTY of volume to fill a relatively large room, should be perfectly at home in a room with about 12' by 12' of space - stereo separation is PERFECT - and sound is CRYSTAL clear - especially using the Optical Audio for input! First of all, I have been someone who can easily hear distortions and bad mixes, ever since I was 5 and my dad's giant Carver stereo with 4 HUGE Altec Speakers (which acted as corner tables they were that big) I have ALWAYS been an Audiophile since I was a little kid, back in the good old 90s of MASSIVE full stereo systems - he gave me his old Technics receiver to use in my stereo system - it was a SWEET piece for a 10 year old kid too! I had some Pioneer's with a 12" woofer, with 5" mids and 2" tweeters - it was 60 watts RMS per channel as well - I even bought upgraded speakers for the cabinets as they were old when I got them, I overbuilt them. Anyway TL:DR This sound BETTER than my old GIANT stereo, and ALMOST as loud and as booming as pop's old Carver + Altecs - and mind you, the entire cabinet for one of these speakers takes up less space than the 14" woofers on Dad's old Altecs! ALL THAT - and the Bass is ALMOST as loud, basically EVERY BIT AS DEEP - and handles the mids and highs even better from what I can recall! And that is not hyperbole - those old Giant Alties had a rated response of 40 Hz to 20 KHz at +/-3 Db - ALL high end audio is rated MUCH more tightly, with not more than 3db of pop or dropoff allowed to make the spec - and these little beauties have a 5.5 out of 10! Only thing I MIGHT ask for still, is a Sub-out (luckily my PC has one) and for the R2000DB to be updated to use HDMI audio in as well as the current connectivity - as HDMI audio is supposedly the cleanest - but I probably would use Optical anyway. And MAYBE just a little more overhead in the Amps - I would LOVE for it to be impossible to cause distortion no matter what I do - but that is unreasonable anyway, its not like anything sounds good with the EQ maxed on every slider - as well as the Bass and Treble control on the speakers
