Looking for an integrated amp around 4000 to 5000.

Thanks everyone for all of the advice. I will look into your suggestions. 

 "those Prima Luna tube amps have an output impedance of several ohms! Hardly good for bass performance! My Dynaco ST70 is far better!

White paper vs anectdotal experience often contradict  what anyone's ears actually like.

Having used the PL HP for 5 years, I've never heard a bass deficiency.
Like all amps-ss or tube, some speakers sound good, some don't with said amp. 

The PL HP has both of the OP's requirements and plenty of flexibility to tailor the sound(tubes) to the OP's liking. It will also drive many popular speakers. Whether  your ears like it, that's all YOU and no one here.

You simply need to demo if possible. All the write ups on it, do provide insight, but no guarantee for your own ears. Reselling if you didn't like it, shouldn't be a problem.

Check out Line Magnetic as another value tube option.

Anthem STR Integrated 20% off sale.

ML 585 under 6k will put you in a very good audio place. 

Hey Pal,

Get 99db efficiency speakers and look for a SE DHT integrated and your done. Good luck!

Buy a Parasound Halo integrated if you must spend the big bucks!

My point is that the high-end market is completely based upon fantasy and expectation bias!

I find that hard to believe. Every day I come here in eager expectation of enlightening information, only to find whiny superstitious nonsense about expectation bias. But instead... oh, wait, I get it! Projection! Projecting your own actions and beliefs onto others! And so although you came here expecting enlightening audio information what you got was enlightening psychology. Which means, guess what? Expectation bias foiled again!

Used Luxman's often run ~ 3,500

My listening experience with the prima Luna 400 via Spendors was underwhelming. Very boomy, sloppy bass. Just one audition, but for an hour. YMMV.

You're welcome.
