E8900

Can the 8900 be ordered preasembled without the Alps volume pot (plan to run it directly from IFI IDSD Pro)
If that’s possible, how much will it cost, shipped in the USA, as reviewed “Full Monty”by HA in the July issue of Stereophile (Lundhall+full AN upgrades+anything else that’s on VK mind for betterment of sound and life), with tubes other than GE?

Cheers
