Out of the the turntables considered, the VPI will be impossible to top. The cartridge Id partner a prime with would be an Ortofon 2m black which would be very friendly with the MM inputs on many integrateds. Soundsmith has great moving iron carts as well. For MC a great match would be Ortofon Cadenza Red coupled with a great step up transformer. My VPI dealer is reference analog in Oklahoma.
I absolutely think you are on the right path with Luxman.
Another almost impossibly musical integrated is the Wells Majestic with 150 watts.....
Devialet would be a wonderful all in one choice and so elegant.....
Klipsch cornwalls would be my very last choice.........horns are just harsh and I revere everything Paul Klipsch did but audio moved on........you can do so much better in terms of overall musicality and emotional engagement. That level of system deserves more......If you like that high efficiency thang tho look at Tannoy
my choices would be:
Look at Harbeth 7es3
Look at Marten Django (unbelievably musical)
Youd need more watts (used Mcintosh Integrated?)
but Magnepan 3.7s would give you the biggest dose of real instruments
in acoustic space in a way no dynamic speaker can.....Ive owned mine for four years and Im ridiculously content but they are big.......
Be sure to browse show videos on avshowrooms You might consider going to Rocky Mountain next month to hear so many combinations.....
The chase should be the enjoyable part of this hobby so listen lots and try not to have any preconceptions about anything......let your ears be the unbiased resource......
ive had a few VPI tables......here is my latest table my first suspended table
Oracle Delphi MK Vi 2nd gen
