    Thank you sir! :]

    This is by far the hardest to photograph mod I have performed. It is so large and multi dimensional...

    The owner is pumped! :]

    Bet that's expensive. 5 figures.

    It actually was not too much more, I now have the channels to acquire 400v MR so it saves cost but not sacrifice performance... :)

    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.

    They are actually SMALL, I like it. The 400v is maybe 40% of the size of the 620v! Definitely a space saver!!

    Example, the left caps are 6.8uf 620v, the middle caps are 12uf 400v

    I think I got some of the last 620v, I have to say I like the smaller size..

    They still make the 620v but the 400v for the price will start to take over! I like the size and price for sure! Might actually be able to squeeze some MR caps on the inside of the LSiM705! :)

    Oh, my bad. I thought the old size was off to the right and the new size, well..... They looked to have been about the size of a half gallon of milk. Silly me.

    Silly question coming......

    Why would anyone need 600+ volt for audio? Obviously there are other uses for them than speakers just can't come up with any....

    Are there speakers that would need a 400v cap even?

    Here's a question - how much would you have to pay retail for a new pair of speakers that are built with this level of electronics inside?
    Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

    Most the guys on here probably don't pay retail
    Typically multiply the parts price time 6 is a rule of thumb for retail?
