best integrated amp.

Ayre makes a couple of excellent ones

If the $5 to $7k is for new, then take a look at Luxman. Lots of features, built in phono and headphone stages. If you don’t mind used, there is a huge array of possibilities. The used market is very depressed right now and if you are patient, you can store a huge deal on gear that is less than one year old at 50% or less than retail.

Wells Audio, is certainly on my must-demo list!

Don't forget to list the cabling in your systems- guys!

Between Vitus snd Gryphon these are substantially more refined then anything under$15,000   and will easily compete with seperates  of similar  cost.
For Pass labs without question the integrated 30, and 60 are much better then the 150. The 30, and int 60 run mainly in class A  you will not get a more musical presentation under $10 k.
