Would a Lamm ll2.1 deluxe slay a Parasound JC2?

I believe that your upgrade with the Lamm will probably surprise the hell out of you and you won't look back, plus the  lamm is tube rectified which I seem to be drawn to, by the way I love mine.

Argon66 are you looking to buy new, if so contact Lamm and they will recommend a couple of their dealers, I did and got 1,200.00 off retail and it shipped direct from Lamm to me.

There was a used LL2.1 deluxe offered just about 3 weeks ago for I believe 3,600.00, it actually was listed twice, which surprised me because they don't come up often, it was a dealer add where the owner moved up the Lamm line. 

Argon, I too have the Lamm and have built my system around it. I went thru around 13 preamps in 2 years to get to it after having and selling the LL2 Deluxe that was part of the 13 pres tried, it was the best in my system hence the purchase of a new LL2.1 Deluxe to end the quest for a pre. I have found some tubes that really are nice in the 12AU7 spots and some siemen 6922, if you get the itch  to tube roll we can work something out to get them to you to try to see if you might want to go that way, I have extras. Go take a look at my system and good luck.
