Best Integrated that you've heard under $5k

I should have added the CODA CSiB integrated that I sold and bought the CODA separates. The CSiB is an excellent sounding piece.

The KRELL K-300i I linked above is smoother (Class A first 90 watts) and is being compared favorably to $13450 Boulder and $40K D’Agastino on Stereophile. I put mine up for sale last week to raise some cash for another upgrade and then came to my senses. I removed the ad.

I think Musical Fidelity makes incredible sounding stuff...I had an m5si and kind of bummed I sold it. Muscular, meaty sound but stays delicate enough on the highs.
Would love to hear some of their higher-end stuff...

Tubes, Quicksilver Integrated, Raven Audio Blackhawk, Pathos Logos MKII and Pathos Classic Re-Mix In Pol. (Pathos are Hybrid)

SS, Simaudio 204I and 340i, Belles Aria, AVA DVA M225's (AMAZING). Had an NAD M10 that was fun also.

Now spend a bit more $6500 to $7500 (now) the Audio Hungary Qualiton X200.

Simaudio has some good integrated that shocked me when I learned their price.

Rega has some nice integrated as well.

And NAD was my first integrated and that brought me years of enjoyment.

I really like Simaudio gear also.  They are pretty expensive and I would have a hard time paying their MSRP, but I was able to pick up a 600i for well under your budget.  I've compared it to integrateds from Heed, ARC, Vincent, and Peachtree and it's better than any of them.  I also have a Simaudio headphone amp and it's the best I've heard after owning a number of different headphone amps. 

There's always something better, and "better" is always a matter of taste (unless you're one of those ASR guys), but if you can find a pre-owned Simaudio integrated in your price range I think most people would find it very enjoyable.
