Looking for an integrated amp around 4000 to 5000.

The mfrs that I have in that range are YBA, parasound, Hegel, McIntosh, Moon, Jolida, Plinius and Musical Fidelity. These are all integrated and I will die with them. I know there are lots of other good choices out there but these ones punch above their weight. IMHO. 

Like Millercarbon, I am a big Raven Audio fan.  Please check out their website and then call Dave Thomson.  He is a wealth of audio information and he has some of the best tubes in the world bar none.  There is also an integrated amp in various price ranges.  I personally owned the Raven Reflection MK2.....simply put - outstanding.  

If you are looking for something different and excellent, you could try a Gato Audio DIA-250S. One of the best integrated you can currently  find, made in Denmark by ex Gamut engineers. I had one paired with my Arts Prestige 8.3, Spendor d7, and Q Acoustics Concept 500. Simply amazing with all of them. 250wpc at 8ohms and 500wpc at 4ohms. It is a class D, but sounds like the best Class A/B I had.
The built in DAC is something special.They are using a direct sales channel, and currently applying 40% off.
You can even add the network module, which is ROON ready. 

I recently replaced a Rogue Cronus Magnum II with a Manley Stingray II. The Manley is quite excellent and compares to much more expensive separates in my main system. If your speakers are efficient enough, use the triode mode. 

For SS:
Hegel 390
Valvet 
Lejonklou

Tube:
Line Mag.
Manley

So, what to do?

Buy a used Pass INT 60.
