Thanks, Chris, that is one thing I needed to know as I'm running all balanced on my main rig and can run balanced on my office rig as well.

The MP website offers a few output cap options, are all four of the coupling caps 2.2 µF?  They look to be the same but wanted to make sure.

Yes all the coupling caps are 2.2uf  and all the tubes must be the same voltage to run in balanced mode.

Again, thank you.

rajacat where did you get the socket saver? Link?
I can't find the link to the particular socket saver I bought. Just go on to ebay and search for 8 pin ones. Here's a link to one.

Can you gents comment on the sonic attributes from rolling the rectifier tubes, please?  I'm familiar with the results of rolling signal tubes.

Here's a huge thread on HeadFi with comparisons/reviews of  5AR4/5R4/5U4G rectifiers.

Umm...that thread is about Woo Audio headphone amps.  I want to know what sonic effects rectifier tubes have on the MP-D2.

I have a few NOS and OS rectifier tubes so I will have to figure it out myself.  I do appreciate the tips about socker savers and adapters raising some fat bottles up high enough so they can be used with the top still in place, thanks. :thumb:

My MP-D2 will hopefully be here just before the end of the month.

Howdy all. I just got one of these and am using it with Roon/HQPlayer NAA/SMS-200 or MRendu and am getting a pop at the beginning of every song - I'm upsampling everything to DSD256. If I just use Roon to upsample to DSD256 no pops. Is any one else that has the MP-D2 experiencing this? Any suggestions?

Thanks
Tony

This is a problem that has been discussed over on Computer Audiophile. It's not unique to the MP-D2. These pops occur on most DACs using  the Roon/HQ combo. This was an issue with the Holo Spring too and discussed on that thread. There may a work around now but I've not been following the discussion recently so I can't give you any guidance.

Thanks Roy. Yes, I've seen the thread on CA. My Directstream doesn't have this problem fortunately ;)

Fine with me. No big deal. I just pasted it from somewhere else in its caps iteration. Sorry to upset you.

Ask joeinid over on audioshark. He has used DSD on the MP-D2 and hasn't mentioned having trouble with pops.

Here's another MP-2 owner who's using HQPlayer successfully with no pops. It's the most recent post. Perhaps the problem is with ROON's software.
