Simple - buy a used Counterpoint preamp just not the slim line SA-3 or SA-5. All you need is a SA1000, Send it to me for modifications - AC filter choke, Audio Note non-magnetic resistors - Amtrans resistors, Nichicon capacitors - maybe Audio Note capacitors - V-Caps, upgrade the volume control. Now you don't have to spend $5K or more. Just peak inside any of the recommendations above. See if anyone of those preamps have any of these parts inside! Short answer - not one of them. Why spend $5K on a preamp that uses below average parts. If you want I will even remove the Counterpoint guts and build you a point-to-point wired version which will just blow your mind.
Happy Listening.
