I was recently thinking about upgrading my 5.1 home cinema system and to switch back to stereo (after moving into the house, I have no space for 5.1 as I'm sitting against the wall, although in 40sqm room). I have long considered putting half the money into electronics and the rest on new speakers. Btw current stereo setup is B&W DM603 S3 from 2002 and Onkyo AVR TX SR805 from 2007.
I now considered used BW 803 D3 and to keep the AVR running for the moment until I have saved enough money for something like a NAD M33 or separates. Instead of buying the NAD with used 804 D3 for the same money.
I will only stream music in the future in addition to TV via Toslink (no headphone amp needed, no analog sources). I considered so many different options but I was getting too confused with the DAC/Preamps/Streamer/Purifi/Dirac discussions that I decided it was easier for the moment to upgrade the speakers and to take time to learn more about all the electronics. Also I would still like to test the AVR on these bigger speakers, than I will borrow the NAD and hopefully alternatives to compare....
The real question is, can the AVR drive the 803 D3 correctly? I found the following measures for the AVR:
AVR measures
The new speakers have minimum impedance of 3 Ohm (8 nominal) and I'm not sure the AVR supports this (4-16ohm) ? Do I risk clipping ?
I have the possibility to bi-amp (bridging to double the power not possible with this AVR) but I have read discussions 10 years ago telling that is nonsense and marketing for AVR?
2nd:
I will probably purchase a Bluesound as a source for the AVR to upgrade to uncompressed audio (currently only using a Philipps bluetooth aptx adapter via coax to AVR) with Tidal , Quobuz or Deezer Hifi. I don't care about MQA. I could go for a better DAC but to be honest my subjective impression is that the family can handle a Bluesound much easier than an Okto Research with Volumnio or other good DACs with limited or no streamer at all. I would love to see any alternatives to a NAD M33 (I prefer when there is at least a minimum of competition in the market) or something like an RME DAC with all the capabilities of a Bluesound streamer.
The question is shall I use the internal DACs of the AVR, 24bit/192khz Burr Brown 1792 (for each channel) or the new Dac in the Bluesound? I guess that if I want to bypass the AVR DAC I just have to choose one of the many analog inputs with an RCA cable (except Phono of course)
Not important but helpful for my own understanding, my AVR is heating a lot and I kept in my mind that it is still a Class A amplifier, can anybody confirm this ? I couldn't find anything in the manual, except a power consumption rating of 870W (or 9.5A for US) or this already a Class A/B ?
I've learned a lot last weeks, don't hesitate to use technical language when responding, even though I'm not capable of using technical terms myself in a foreign language. If people tell me my plan is complete nonsense I can change it but first I need to understand why. I know the importance of room correction, and Dirac vs my old Audyssey is not comparable. But for the moment I would feel sad to replace the AVR before even having used and tested it correctly.
Thanks guys for all the help you are providing here !!!
