Sun Audio SV-2A3:: Direct or not?

How many Sun Audio SV-2A3 amp owners use a preamp in their system. Is there a sonic advantage in connecting a CD player or other digital set-ups directly to the amp bypassing a preamp? When used with a preamp, should the gain on the amp be turned all the way up?
Thanks for any info.

I use a custom built tube preamp with the Sun SV 2A3, which I also mod to replace 6SN7s with WE 417A tubes. They sound perfectly awesome with spatial, detailed and sweet.

Yeh, but have you checked out the price of NOS Western Electric WE417As?

Average price of a pair WE 417A right now on ebay is USD$60-80. Whereas top line of 6SN7s are sold with untoucheable price USD$150-200 like Mullard ECC33 or rare TungSol VT231 round plated. To me WE417A is best choice of input tubes for 2A3 and/or 300B amplifiers. Do not underestimate the little tube like WE417A/5842!!! You will be surprised if you know how to mod.
