Sonic frontiers Line 1 2 3 owners

I would have to say, for 20 bucks, who cares?! I mean really, at that price why not just give it a try. If you hate it, put the old volume control back in and go on with your life! Happy listening!
Thanks Jond, That is a good idea. I did not think about that. But what if it smokes?
If it smokes just remember not to bogart it! Sorry couldn't resist. Honestly since it's just a simple volume control I don't think you really have anything to worry about. Good luck!
I emailed tech support at the Parts Connexition who are undeniable the most knowledgeable when it comes to the SF products and asked their opinion on this upgrade. Below is their response:

In our view, the improvement which could be attained with this chip is ONLY possible when you run it at the higher supply voltage (capable in the 2311).....but since the supply voltage is not altered (and I don't think you can raise it in the LINE-3), the spec's should be about the same.....that was our position when we first looked at it 3 years ago.
please check my commentary in this audiogon listing.i buy this upgrade and i am very satisfied.
