Better Integrated Amp?

 awesome

3rd, the Yamaha A-S501 85 WPC + it's 4 ohm compatible which let's it be
used with a wider variety of speakers.

Like the volume control comments. I need 1 decibel increments. Also nice if volume display is dimmable, but may be getting a bit into the woods. 

The marantz pm5005 is an excellent all analog affordable integrated amplifier. Way better than the Denon. $499 I believe is the going price, although you may if lucky get it on sale. It is a very well made and thought out amp. No built in dac, no digital anything and it sounds wonderful. Here is a great review of it and the matching cd5005 cd player, which I also recommend very highly. I’ve owned both, but then graduated to a higher tier. Pair these with the wharfedale diamond 220’s and I think you will be very happy. Link posted for the diamond 220’s as well below.
Alternatively, the Dali Zensor 1 would match up well.
You will have a killer starter system guaranteed! All this for a tic over a grand! What wonderful times to be into hifi....

Rega Brio R is a solid integrated with a fine phono stage for a start. I call that amp “the gateway drug”. Hahaha. They can be had for reasonable price now used. I’ve heard that little amp drive harbeths, quad z2’s, Wharfdales, etc etc just fine. It’s a very pleasant sounding amp. I ran it with a grado black cartridge with 8MZ stylus with some wharfdale diamond 225’s (my first set up) and it was a very nice combination for the money at that time. Same set up now could be had for 450$ total maybe? Not sure about used UK market. Might be better for those brands actually. Good luck.
