Advice on Integrated Receiver

Hint 6 yes, Anthem STR, maybe Pass Labs INT 60 or Luxman 507z or 509x would be my start points. I would imagine the Pass (and know the Luxman) can let you bypass the phono preamp as mentioned above. I’m also going to throw another vote for the Hegel H390....great value and tons of current. Enjoy the search!

EDIT:  just scanned the classifieds here.  There is a Hint 6, an STR and (new entrant) a Marantz PM KI Ruby all available.  Several of the Hegel H190's too.  The Ruby is a great value IMHO.

Post a pic of your room if you can. I’d bet there’s some placement work to be done.

@bound4h this is just one man's opinion but those speakers can take you farther in this hobby than your amp can.  And the reason I know is because although I had big intentions of upgrading my MA S6's I've not yet gotten around to it because they sound amazing.  I put the Luxman 509X (endgame piece for me, no doubt) in front of them as @audphile1 recommends along with better source and I've been thrilled.  Check my virtual system.  Note my room is well sorted also, so a pic of your setup might help us here too.  

If I were you and upgrading I'd look used Pass or Luxman out of the gate, Maybe Parasound or Anthem if really trying to stretch the dollar.  

@bound4h what @audphile1 says above is spot on.  People suggest all the time that they just add power to their AVR and I cringe, because i've A/B tested mine and it's not really close.  

One more thing on the MA front.....when my dealer came over to final tweak my subwoofer settings, he said "I don't sell this brand but can't say anything bad about it" and further "I've seen people spend a lot more and get a lot less performance" than I was getting.  While I think part of that was a complement to a speaker that punches above its weight class, it was also a testament to a well sorted room.  So as others have asked would suggest you post a pic of that, as it's a $0 fix.  

@bound4h if you can get there Luxman is an excellent pairing, IMHO. I didn't realize the Hegel had no phono input. Definitely a deal breaker for many.  

As stated I use 509x with an older MA silver, the equiv of the 200 today. I do have a sub but even before that my ears said no mas long before this amp ran out of juice. Here’s what I consider an EXCELLENT description of the sound I get, lifted from a review that is accurate to this day.

For argument and sake of reference point, if you were to put Boulder amplifiers (and we still had the 1100 series here for comparison) as straight-up natural at 12 o’clock – adding nor subtracting nothing, with no sense of added tonal saturation, our reference Pass XS Pre/XA 200.8 is probably at about 10:30. With going to the left a bit on the warm/saturated side. The Luxman 900 series was about 11:30, with our tube references the PrimaLuna EVO 400 and VAC i170 coming in at about 9:00 and 9:30. I’d put the recent Esoteric integrated about 12:30 – slightly to the cold side, and the last few Simaudio amplifiers we’ve reviewed about 1:00 – even more clinical. The L-509x, like it’s larger separates has that same touch of warmth/saturation, without being slow or non-resolving.

To me that 11:30 reference (slightly warm but still very accurate) is the goldilocks of sound.
