Audio Research PH3 ideas:

...I'm thinking about mounting a position switch for different load resistances(not at all complicated)that I can design as an external unit that connects in-parallel to the rear pannel through the locking pins so that won't degrade a look of the unit.
Can it degrade a sonic performance and how and in what cases?
Also Is there any possibility to acquire SE upgrades kit?
i do not know about the diy switch. but michael percy audio sells a se type upgrade kit for the ph3. i hear it is essentially the same thing as the arc version. i did not do the upgrade. i just bought a different phono stage.


Audio Research claims that switches will degrade the sound that's why they don't use them. If you want to do it you should use the highest quality switch you can find.
