With almost 70dB of gain at that frequency it’s quite good!50hz hum dominates sinad? O shit
They are not able to design simple PS?

Yes, but 1 or 2 cheap caps in right place would make it better and cancel the nasty spike!2dB to 4 dB lower SINAD than the Cambridge audio duo nice!
They’re more or less the same with the duo having better RIAA.Would a different transformer likely improve the noise? There’s a bunch on AliExpress but no idea if they’d do anything to help, or just make it even worse. Like https://m.aliexpress.com/i/33004756346.html
Wondering whether to keep my Cambridge Duo or swap to this; published measurements make it look better, the ASR measurements suggest it performs worse?
I think that the cartridge specification and a bit of maths can tell you if the impedance matching features are useful for someone.They’re more or less the same with the duo having better RIAA.
The impedance matching features of the Mani are kind of nice but without a test record it’s difficult to know whether you can make good use of them.
S/N measurements are gain and input voltage specific.Is there anyway to reduce the mains noise or it is what it is?
Also, a bit confused on the SN ratio. Schiit reports it at 96db (which would smoke the competition). But, ASR found it to be only 81db? That is a pretty big discrepency and seems like the Cambridge DUO still wins?
Not intended to come across antagonistic, but what will be your plan moving forward to reduce the possibility of this occurring if we order one online?We were getting less transformer noise from our AP. Might be due to a delamination in the transformer we sent. Sadly, it happens.
I am sending Amir a new one. Should see better results without a humming transformer.
Not antagonistic at all! We actually changed our supplier of wall transformers to an American company that sourced the product from Taiwan about two to three years ago. We found the were more reliable overall than our previous supplier.Not intended to come across antagonistic, but what will be your plan moving forward to reduce the possibility of this occurring if we order one online?
An artifact of an older product. Filtering has solved that issue.I tried 2 of the Mani 1s and both exhibited radio interference in my system. A local station would come through no matter what volume I had my preamp at. Only phono preamp I've owned that did this, through 2 samples. Has anyone else had this experience with the original Mani and could any fixes in v2 address this issue?
I have heard of this from other, never had that at all here. For what it's worth tough, Most people I know in my city can get like 5 TV channels out of an Antenna... In my building I get one... So I may not be the average.I tried 2 of the Mani 1s and both exhibited radio interference in my system. A local station would come through no matter what volume I had my preamp at.

@amirm will you retest?We were getting less transformer noise from our AP. Might be due to a delamination in the transformer we sent. Sadly, it happens.

Sure, I will retest. And yes, I have a turntable (kind member donated it for testing a while back@amirm will you retest?
Do you have a turntable?
