Best integrated amp for 10K


Currently changing system to match new Quad electrostatics. Looking at tube amp/preamps to match with Quads, but concerned over limited space in home theatre cabinet. Heard great things about VAC Sigma 160i and Ayon Audio Triton III integrated amps as being fabulous for the money. Budget around $10k. Any thoughts from people with these 2 units as to matching with the Quads? Any other options?

The cult following for ESL's and Atma-sphere is very simple.. ESL's draw a tremendous amount of current on the high frequencies and very little on the lows ( this is the exact opposite of a conventional loud speaker ) Atma-sphere excells with this type of load! Sorry for the quick response I have to pick up my 3 year old!

Cheers!

P.S Call Ralph at Atma-Sphere he can explain it better!
Thank you all for your input! Intrigued by the opportunity to get into a used Esoteric A-100 or Jadis DA88S as other great options. Wish there was an easier way to compare these choices.
Do yourself some justice..give the power hungry Quads the Nitro they really need..the $6000.00 giant killer integrated..the Musical Fidelity M6500I..puts out 500 watts continuous into 8 ohms and 850 watts continuous into 4 ohms. Weighs 63 pounds.
