Nice AVR
Style: AVR-X1800H
Refurbished and looking like brand new. One small scratch on the side. It went in a cabinet and it's hidden. All paperwork seemed to be there. If I didn't know it looks like factory sealed . I've got an older Denon. Just wanted to move up to 7.2. Audyssey recognize a second sub. But neither did my older on. No problem with that though. Just FYI. After the original setup and minor tweaking it sounds fantastic for me. I haven't had it but a few days and I hope I get many years of enjoyment from this

Very good audio receiver for my tower speakers and record player set up
Style: Stereo Receiver, Configuration: Receiver
I have had my 1980s Roger sound lab CG 82 Tower speakers connected to a 1999 Technics audio receiver. I use this set up for Radio and my record player. After many good years, the low end on my audio receiver gave out. I have had it serviced before, but I have owned it for five years and it is a 27-year-old piece of gear that has seen better days. ChatGPT led me to this receiver. It took me less than five minutes to connect my speakers. What I love about this receiver is that it’s so simple to use. The radio signal is very good right out the box without an additional antenna. I was resistant to buying a Bluetooth receiver, but it connected to my iPad and my iPhone in seconds. Now I can play backing tracks through my Roger sound lab speaker speakers while I jam out on guitar. No issues with sound quality or anything like that. Runs cool and quiet. If you are a total audio file, you could buy something more expensive. I am a musician and I listen to vinyl. Mostly jazz and classical, and this is fine for my needs. For most people running a record player, looking to modernize with a Bluetooth enabled receiver, this will suit your needs.
