Best used integrated under $5k

djones51 ha.  Most of those other options are bare bones.  Not sure if any offer base management, especially for two subwoofers and none that I can tell have home theater bypass.  HT bypass was something I didn't think I'd use but I do now and LOVE that feature.  It allows me to use my front two channels in HT and 2-channel.  A benefit not afforded with any of the others.
The Hegel will drop hard in price soon and makes me think $5700 is overpriced.  Demos are already selling for $3500. 

Over the $5k mark, I'm not sure why you'd want an integrated when you can get separates like the small form factor of PS Audio's Stellar Gain Cell DAC with M300, M700, or M1200 amps which should outperform all of these in most regards.

I bought a used McIntosh MAC6700 well under that and it has everything I need. You might even be able to get the HD Radio TM-3 Tuner for it and still be under $5000 too. I am still amazed by how clear HD radio can sound through my system, and I never even listened to the radio at home until I had it.

Also, I heard the latest Anthem STR at Axpona in 2019 running into a pair of Paradign Persona 3 speakers. They had it set up in a hotel room (as is most of the show), and I thought they had the absolute best sounding hotel room in the whole place. I don't think you could go wrong and I think you could get that new under your budget number, and probably even less if you could find one used.
Good luck!

djones51 and dtximages - thank you for pointing me to Anthem. It wasn’t on my radar. While I am was originally looking at brands that have more of an audio heritage, makes sense to look at Anthem too. 
Djones51 - in my post yesterday I did thank everyone collectively for their inputs, that included you as well. 

This at the very low end of your price range but I thought I would mention it in case you might want to direct some of your budget to other upgrades. Denon made a series of integrated amps with the designation PMA-2000. I have the 2000IVR. They have 80 watts per channel into 8 ohms and double their power into 4 ohms. Mine weighs about 60 lbs and is extremely well built. I run this integrated in my desktop system but I've compared it to my Krell separates in my main system and it holds up surprisingly well in sound quality. Many people would turn up their nose at a Denon integrated but they would be missing an amp that is better built than a lot of high end brands. These come up now and then and go for between $500 and $1000.

marrduk24 if you don't want the Anthem's bells & whistles but still want a flat out incredible dac, look at the PS Audio Stellar Gain Cell separates. They're small for separates and I think would best any of these options sound wise.  At least to me, they did.
