but make sure not the skinny bottle GZ37 ,nothing special.
do yourself a favor and try these.I have had these 6n1p-ev tubes sitting around for months. Well I finally decided to give them a try, was using 6n23p.
The 6n1p-ev were dirt cheap like $20 for 8 tubes. Fist impressions, less bass and not as defined.
The mids and top end are a little more emphasized or maybe you just hear them more because of the less bass.
I have given them maybe 100 hours or a little more. A little smoother now, I like the top end
I just wish they had a tad more bass. if I didn't know any better I could probably live with them.
The 6n23p is more of a well rounded tube, I may try some 6n23p-ev.
has gary leaked any info about the upcoming mp-d2 mk3 ?
modwright is doing mods on the mp-d2, don't know which version or the cost.
Hi guys, RE the Musical Paradise DAC, I actually have MP D2 DSD DAC here, with AKM DAC chips, Mundorf coupling caps and USB input.
I am shipping the first unit today, with the following mods:
Re-biased tube analog stage (optimized for 6922 driver tubes) and replaced signal path resistors with Tantalums.
Revised power supply operating voltage as part of bias revision.
Added our own SS High Voltage Regulator circuit to provide rock solid regulated B+ to the tube output stage.
Bypassed the B+ and regulator rails with MWI custom capacitors.
It sounds MUCH better than stock now!
It is actually a well designed and built DAC. In stock form, I found the soundstage to be too diffuse and the tonal balance off. When I looked at operating bias and where the 6922's were operating on the tube curve, I could see that they were operating in a VERY non-linear region. Once this was resolved, alone, things got much better! I then added our own SSHVR (Solid Stage High Voltage Regulator) with MWI bypass and the B+ became VERY clean and VERY tight!
This translated to tighter and better defined bass and control across the frequency spectrum. The combination now, of proper operating bias, upgraded tube signal path resistors and regulated supply, gives the music a controlled but natural and organic flow.
I am very pleased with the result!
Finished photos to follow.
Thanks,

Dan, what is the cost of the mod?modwright is doing mods on the mp-d2, don't know which version or the cost.

Aneep, what denomination and type of capacitors advise - Audyn True Copper or Audyn True Copper Max ???Here's a combo based on my experience -
WE422 rectifier
6h23n 1975 silver shields
Audio magic fuse
Dueland or Audyn caps
Less Loss power cord
Cheers
