Your Denon receiver is a nice unit but your Focal speakers really need a better amplifier. You could use the Denon as your processor connected to a separate multichannel amplifier.

Height speakers might be a trick, that room is an acoustic nightmare.

I do have experience with Revel...very nice speakers.

I would say you should first and foremost focus on the Denon replacement/upgrade. The processor is pretty good it's your amplifier that is your weakest link here.

Consider Monitor Audio. I was reluctant to sell these at first but then gave them a try and they far exceeded my expectations. It's the only brand I sell these days along with their amplifiers and my customer response in every case has been very positive.

There's so many good speakers out there. Listen to whatever your interested in first.

I got this complete Fisher 871 Hi-Fi stack from my uncle, circa 1986 and all made in Japan! He recalls paying over $1,000 for everything in 1992, according to the date on the cabinet booklet. Fortunately, he kept all the documentation. There may be a receipt, but I haven't gone through the paperwork yet.

System includes the main amp, equalizer, compact cassette deck, turntable, CD player, and radio. All operable with a single remote.

I took the lid off the receiver to check the condition of the electronics. Everything is well constructed and very serviceable.

When he powered it on years ago he reported no sound. It sat it his garage since he moved in 2005. Everything was still connected when he moved the cabinet. He is bringing the speakers next weekend.

I'm determined to get it all working. Starting with filter and coupling caps in the receiver, and refreshing the power amps with new thermal paste.
