Get an old ARC tube pre. I own an ARC SP6B. This set up and circuitry seems to be a common theme for many of their preamps. Mine has gain from hell and tubes.
Even though I am a devoted tubophile most old stock tubes make some noise. It takes very careful selection from a batch of new or current production tubes to find the few quiet ones. BTW I tried the switch to lower Mu tubes and it had almost no effect. If it is a high current pass through tube like a 12AU7 forget it your woofers will wobble like a bowl of jelly.
The phono is amongst the legends. The later ARCs seem to switched to the 6922 for a quieter outcome but they aren't necessarily quiet either, believe me.
