Why has there been no posts on this thread from anyone who actually purchased the MK3? What am I missing?

Hi Bob,
Do you have a chance to do any critical listening after you install the new rectifier? BTW, which rectifier did you get?

Hi chanv64,
Sorry for the delay in reply. I have tried 2 aftermarket rectifiers. Both are 5U4G type, and both fit in the case's top hole (with clearance) without modification or socket saver required.
I have a used Westinghouse from around 1967, and a brand new Psvane "247B" (it's really a 5U4G). I honestly cannot hear a difference between the 2 5U4Gs, but there is an improvement over the stock rectifier supplied with the MP-D2. The Psvane has about 50 hours on it. I'm under the impression it'll improve further after 100 hours.

The most dramatic change in sound came from swapping out the stock driver tubes with the BEL E88CC. The sound between stock and aftermarket tubes is like listening to 2 different pieces of equipment. It seems very sensitive to driver tube changes and I now understand why most owners have boxes of extra tubes to try out.  :D

Hope this helps. Let me know if you have any other questions.

try the sovtek 6h30pi, great all round sound.  it's taller than other tubes, tip just sticks out of the hole.
there are reports that the 6h23p also sounds good, but i have not heard it.

I've had the MK3 running for a full two week now and this is a serious audiophile dac. The soundstage is immense, the notes are rich with detail and it makes me want to listen. The MK3 is a big step up from the MK2 IMO. The usb has never faultered to any material I have tried or missed a connection. Even my wife was impressed by the sound. Gary's claims of more bass is correct, but I feel the bass is more accurate and dynamic. The mids and highs are wonderful. Voice has all the nuances and feel they should. The highs are clean and have sparkle. Not goey, but accurate. The MK3 is easily worth the money. My 2 cents.

In my system the 6h23 was a far better sounding tube than the 6h30.  I like the stock tubes better than 6h30's but just my preference as I don't like 6h30 based preamps either.

I didn't care for the Russian tubes and found the 6922 PQ and Brimar 6922 to my liking. I have several different rectifiers that I can roll and find the rectifier is a valuable tube to have for this dac.

I would like to know as well, I'm really thinking about one of these  ( MK3) for an office.

I am using Mundorf 2.2uf Silver/Gold/Oil caps. Tubes are Amperex USA 6922 and Mullard U52 CV575 rectifier. I have several rectifiers, but wanted to let this break in. The caps were from my MK2, so they were well broken in. I have the new ES9038 pro chip set. The sound is awsome IMO.

Hey thanks.  I was thinking about getting both the ESS9038 installed and getting the AK4497 module.   I was noticing that they are offering the Mundorf 2.2uf Silver/Gold/Oil caps as an upgrade option.

It's a bit disconcerting on the ordering webpage for the Mk3 it still says Mk2 on all three choices for DAC chips.  Also note that one can buy the four Mundorf caps from Sonic Craft for about $40 less and matching to 1% is only a dollar each.

I saw that, but a lot of manufactures are late in webpage updates and simple email handles most important questions. . .  And regarding the caps, I would rather have them installed and tested before I ever got the unit.  IF I bought them I would go through https://www.partsconnexion.com/capacitors-film-mundorf-supreme.html

You almost got me there, mav52.  Your link is to the Mundorf Supreme and the cap referenced by Tubeburner and MP is the Mundorf Supreme S/G/O.  Quite the difference in price and performance.  As to wanting them installed and tested first?  Each to his own, I installed my caps myself no problem.  I bought my DAC used from an AC member and it had two Supreme S/G/O's as the previous owner operated in single-ended mode.  I wanted to run fully balanced so I needed two more and I wanted them matched.  Since PO had bought the first two from Sonic Craft and they had that info available they were able to make a very close match to within 0.2% tolerance.  Partsconnexion is an excellent company and I have purchased from them many times in the past.

I would love to be able try a set of Jupiter Copper Foils but @ ~$800 it won't be this or next week!  :lol:

If you are running single ended, you just replace two caps. If balanced, you replace all four caps. Sonic Craft does a nice job with cap matching. Easy to install in this dac. You can email Gary with questions. He responds in a reasonable time.

Hello. Does any body know what frequency is required for the clock inputs on the ess9038pro dac boards? I mean not the masterclock input on the back side, but the sma or bnc connectors on the 9038 dac boards. Thanks in advance.

Just wanted to provide an update on my MP-D2 (AKM4497 chip) Mk2.

I picked up a pair of Amperex 7308 (orange labels) to try out and compare with the BEL E88CCs I had previously installed.

The BELs were a huge improvement from the stock tubes (which made the MP-D2 sound like it arrived broken). They provided an increased gain, overall more forward "here in the room" sound and slightly emphasized top end sparkle (but not fatiguing). Worth a try if you need to brighten up a dull/flat system.

By contrast, the Amperex tubes sound a bit darker, definitely fuller in the mid-bass, and provide slightly fatter/looser low end. Overall bass output increased a bit, but not to the point of overkill. Worth a try if you want to plump up a thin system, but not what I would consider a "bargain" priced tube. I'd be interested to learn if there are any newly manufactured, sanely-priced, tubes that MP-D2 owners are jazzed about.

In the name of further tinkering with this unit, I ordered a pair of Mundorf Supreme Silver/Oil caps to try out. I don't feel I need a cap upgrade, but am curious to hear what (if any) difference in sound they provide. I'll report back once they've had some significant burn in time.

Still running the Psvane "274B" rectifier tube, and find no need to search for others.

I'm very satisfied with this tubed DAC and the flexibility it offers.
