The best phono stage out there?


I have recently purchased a basis turntable and was wondering what analog lovers think is the very best phono stage they have heard . I currently use the Sutherland PhD and like it very much but have not really had an opportunity to audition other great phono stages. The cartridge I intend to use is the Dynavector XV-1S .
Thanking you for your opinions

Well the best might be the Whest Reference it just conveys music.
Its strange the Tron being mentioned I heard it a few times and to my ears it was slightly coloured having a dark presentation. But there is a chance this was the system. It has tremendous resolution but so has the Whest Reference
I think what makes the Whest reference special is manufactures like Amazon and Raven who use it there system
But as it been said earlier there is no real best just about preferences
The Boulder 2008 is probaly the best I've heard, but at $33,000 it is pricey. I own an Aesthetix Rhea that is very close to the Boulder, and an ASR Basis Exclusive that might equal the Boulder, but I have not been able to directly compare. For the price, the Rhea would be very hard to beat.
The best is the one YOU like the best, the question is how to find it; popularity polls are of little use. Set down the elements of sound reproduction that are the most important to YOU and try to decide which one you can afford matches it best. The beginning of wisdom in audio is the recognition that THE BEST does not exist and what you are seeking is the one that best conforms to YOUR ideal of sound reproduction. Being able to recognize what that ideal is is the end of wisdom in audio. On second thought, forget everything I have said. The constant search for the HOLY GRAIL provides old timers like me with a never-ending stream of great equipment at good prices.
