B&K 507 has died. Thinking of going 2 channel?

I have a pair of kef 104/2 speakers that I originally paired with a Nakamichi PA7 power amp. I sold the Nak and bought the B&K 507 and a Kef center channel. The B&K has stopped working and I am torn between which way to go. I am going used due to financial situations (son in college). I am considering another Nak PA7 or something else 2 channel. The Nak with the Kefs always seemed a little dark to me. I would like to be able to remote the volume from my chair which the Nak CA5 preamp wont do. I liked the 507 till it died today. I did not care for the SR10 remote at all. You guys know what these 2 items sell for used, I just wanted some alternatives that would be reasonably priced. I have not looked at the market in ten years so I am definitely out of the loop. Thanks for any input.
Ditto above if on a budget the Emotiva gear is hard to beat for the money. I have their small amp and a DAC. Tough to beat, new with warranty, and priced very well.

You do not mention your budget but brands such as NAD and Anthem, Marantz would be on my short list.
Which models of the prior post listed brands would be good to look for used? NAD, Anthem, Marantz model numbers? Music is my first consideration. Thanks for the replies.
I'm torn between a Emotiva preamp, a Marantz av7005 and a 507 B&K The B&K is less but I want to make the right choice and I live in an area that requires lots of travel to hear anything close. I know the B&K sound and I liked it OK but would really like to improve if possible in my budget. I know I would need an amp with the two preamps. Someone point me in the right direction for music first and HT second. Help because I am close to pulling the trigger. The Marantz AV7005 is 800 used. The Emotiva is new and the B&K is used.
I don't think the Marantz will sound as nice as the B&K. I know what you mean about the remote. It has always been a clunky issue with B&K products. Would an integrated work for you? Do you need a reciever with tuner? Do you need a AV receiver with muti-channel and second zone?
