I have two LS-50 speakers being driven by an inexpensive Yamaha AVR (RXV-679) and am not happy with the quality of the audio. The setup is ok for watching movies but not very satisfying for music listening. I want to upgrade and am considering buying a new AVR (like the Yamaha 2080 or 3080) or going with a stereo integrated amp (e.g., Riga Breo or equivalent) plus a streaming device with a high quality DAC. I currently am not using surround sound speakers but would like to have that option for future consideration. I also plan to add a subwoofer.
I have a vinyl collection that I haven't played since my 40 year old Yamaha stereo receiver died but will need to buy a new turntable and cartridge. My Dual 1009 has not been used in over 10 years and may not even be serviceable.
So the first question is whether I can expect decent audio quality from one of the high-end AVRs or are they simply outclassed by a good integrated amp selling in the $500 to $1000 range? Put another way, does the AVR option even pass the "laugh test?"
One other complication. I recently moved into a new apartment that combines the living room dining area and kitchen in an "open living" configuration, The size of the room is about 8 x 8 meters with a 3 meter ceiling. Is this going to be too large for the LS-50s to fill? And if not, how much power per channel will I need to make them come to life? I'm assuming it will require at least 100 watts into their 8 ohm impedance.

@bigboss I attended the first Big Question in 2009 comparing stereo speakers. Anyway they gave us a tour of the "Towers" and in the Cinema testing room they had a Arcam AVR 600 powering some Mordaunt Short Performance 6 speakers. That is still one of the best set-ups I've heard below silly money.
More recently, about 5 years ago one of the dealers I buy from had a Yamaha warming up with PMC Twenty 23 speakers. Again that sounded very impressive.
Unfortunately hi-fi and music in general is always going to be a compromise. It never has been or will be an exact science, but if I had the need a multi-channel set-up I would be happy to play my vinyl and CDs on it.
So to answer your question: Yes a dedicated two-channel will be better than a receiver at music but the compromise with even the best integrateds is a lack of flexibility. It's whatever fits your needs and room the best.
