    Clarity Cap ESA
    Mundorf Mox Resistors
    Jantzen Inductors

    Midbass/SDA Network -Clarity Cap ESA
    Jantzen Inductors

    Gimpod boards too

    200 Hours or so of burn in

    3) Record them modified!

    This will be a fun project for sure!

    Also make note of the changes in spatial properties between the stock and modified versions.

    ...in the results of this mod! (Especially since I own the pair to be modded)

    Have you spent much time with the 1.2's before the mods? I'm interested in a before and after comparison given that you're using, among other components, Clarity Cap MR's.

    You're investing some serious coin!

    I've had the 1.2 TL's for about 10 years but am the original owner of SDA 1A's and 2'A's. I did the crossover upgrade on the 2A's and was quite pleased with the results. Reagan

    I have another 1.2TL coming for modifications that is what I would describe as "Balls Deep"

    Clarity Cap MR on the entire tweeter network, all 12uf and .25uf caps and the midbass/SDA is all ESA.

    I am a little pumped about this!!

    I am really thinking about putting the Clarity MR12's in my crossovers. I'm sure I will have to reconfigure my setup for them.

    Maybe I just buy them and plan on doing a full point to point external crossover..

    I have a brilliant idea to make the MR work and not even make it look like a mountain ;)

    Tony should build a new board. You know, his original seems to have gotten a bit cramped.
    Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

    Who was it that said size doesn't matter?

    Tom
    In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence.

    The best way to enjoy digital music reproduction is to never listen to good analogue reproduction.
