Best bang for buck integrated amp for $500

Also, I had the Yamaha AS-301 and wasn't impressed with the phono stage in particular.  That range of amps is also quite large and can dominate a smaller space.

The Rega IO looks nice like the desktop idea, but 30 watts seem a bit weak.

I have a 20 Watt Quicksilver Integrated that will leave you slack jawed with it's sound. My modest office system is QS Integrated, Bluesond 2i Borderpatrol DAC and Klipsch RP600M's and it rocks!

If we’re talking bang for the buck, might I suggest Marantz? In my experience you either love the Marantz "house sound" or you don’t.

IMO, warm and well rounded. Has "direct" function that bypasses the Marantz tone controls. Marantz has always been conservative with stated power ratings. I have a pre-owned PM8006 from TMR rated at 70, review tested at 90. It’s been said if you want that "classic" British speaker sound, Marantz and Wharfedale.

Having said that...

IMO, you simply can’t go "wrong" with NAD new/used at any price point. Pre-owned NAD will be next on my second system rack replacing a Marantz PM5005.

Wow I don't even know where to begin I got so many suggestions.  I will say the marantz PM 606 does look pretty sick looking haven't heard the Moran sound in over 20 years.

I never knew choosing an amp would be this difficult.

With time comes experience.

Welcome to the journey.
