Sorry if this has been answered before. I've searched the forums but have come up empty.

My question is..
I have a SimAudio Moon Titan HT-200 7ch amplifier and would like to know if it is a common ground amplifier...?

Thanks in advance.

    Best bet would be to get ahold of the folks at SimAudio and ask. Because it is fed by a single toroidal transformer, I am guessing that it is, but on an amp like that, I would ask first.
    The Gear... Carver "Statement" Mono-blocks, TriangleArt Reference SE with Pass Labs Xono Phono Preamp, Walker Precision Motor Drive, ClearAudio Goldfinger Diamond v2 cartridge and Origin Conquerer Mk3c tonearm, Polk Audio "Signature" Reference Series 1.2TL with complete mods, Pass Labs X0.2 three chassis preamp, PS Audio PerfectWave DAC MkII, Krell Evolution 505 SACD Player, Pioneer Elite SC-LX701, Oppo UDP-205 4K Blu-ray player, Sony XBR70x850B 4k, Polk audio AB800 "in-wall" surrounds.

    Saying that it's "too hard" to pursue your dreams is no different than admitting to yourself that you are too lazy to achieve them.

    I believe you can also use a multimeter and check the resistance between the terminals, but don't go with that until someone backs me up! :)

    I've always thought the goal of high-end audio was not to have your neighbors bang on the wall and say, 'Turn that darn music down' but to have your neighbors bang on the wall and say, 'Tell your friends to go home and you can practice later this week'.

    There are two transformers in the 5 and 7 channel versions of the amp. Only one transformer in the 3 channel version. Good idea to check on it to be sure given the fully balanced design it has. The owner’s manual does not say anything specific about grounding but does advise on how to share output between the channels to take advantage of both transformers. My guess is it is common ground.

    Cool amp.

    Thanks guys... I keep reading the owners owner's manual over and over in hopes that that portion would make more sense to me

    I'll check it with a mm tonight while I wait for SimAudio to call back...

    Well... I did the continuity test on the BIG 7ch Moon Titan last night...
    This amplifier utilizes two transformers, one for 4 channels and the other for 3 channels. Turns out that it is only a common ground on the chennals that are powered by the correspond transformer.

    Luckily I was able to find a Dreadnought and it should be here Monday...YaY!!

    Just checked FedEx and the Dreadnought looks to be out for delivery today!!

    Yesterday I pulled a dedicated 30amp line just for the full Moon to eat off of...
