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! :]- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

I am getting to build another one of these monsters but this time even CRAZIER! :-D
All MR! I am going to add a horizontal strip towards the back to mount the large inductor on! Will be fun!- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

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... - Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

I like the size of the 400v MR!- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

Whoa! Them's some biggun's...~ 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. ~
-
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- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
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! - Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

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.

haha! That would be AWESOME! I would need a bigger shelf for sure!- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.

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 are some resources -

I'm guessing about a $1200 build?Main System- Scratch built 2A3 , Lightspeed preamp, Technics SP15/Graham/XV1s,Klipschorns w/ALK xovers/Trachorns, Speakercraft MT8(4), Sonos ZP90, Yamaha Aventage for surround
Office System- Adcom GTP500, Bedini 45/45,Lexicon RT-20,Enlightened Audio DAC, Polk SDA2.3TL, Northcreek Borealis -
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?Main System- Scratch built 2A3 , Lightspeed preamp, Technics SP15/Graham/XV1s,Klipschorns w/ALK xovers/Trachorns, Speakercraft MT8(4), Sonos ZP90, Yamaha Aventage for surround
