Yes, Poti is essential, the signal goes through it. Normally the signal looses a lot of its quality based on cheap design (material ---> signal transfer ability) But before, it will reach the Preamp via its $6,95 RCA connectors. To replace these is even more important with High quality units (Eichmann Phono Pods for example) ....
Volume control upgrades-
I have been into this hobby for over 25 years. I just completed my 3rd volume control upgrade on a preamp and was reminded just how much of a huge upgrade it is. By far, I feel the most significant upgrade one can do, regardless of cost.
This time I used a Goldpoint attenuator, which cost $150. I added a Bent Audio remote control system for $200. Labor was $200. Just incredible. The preamp had a standard $5 volume pot in it. In the past I have used TKD stepped controls.
I am now at the point that this change is an essential one.
Thought I'd share with others as it really is a low cost upgrade.
