We tested 6E5P with Metglas amorphous U core otuput transformers
This sounds like a $10.000 DAC price range. But @miro1360 DAC too...So I'm not smart enough anymore..🤣

6N6P, my mistake. I didn't make it, that's why I told you wrong. I was thinking about the 6E5P, that I have two pairs. Excellent pentodes and cheap, just to be connected as a triode. The only thing is that not every 6N6P sounds good, you have to find the ones from the 60s of the last century.
It also has a 6SN7 socket, and that sounds great too. It's just a pain to decide. 🤔
It can also be 7N7, but anything else can be applied.
Since the dimensions of that tube device are quite large, I would have to make two boxes, and the price is not negligible either. So I will stick with the Sparkos SS3601. After that it can go to my tube preamplifier or my solid state preamplifier, if desired. You liked the SS3602 preamp more than the tube preamp anyway. The opposite is the case with me.

I thought you had two identical DACs with different output stages. This is not a fair game with all those cables. 6E5P is a good tube, but it can be implemented better for DAC tube output. (without iron in the output and with a much better power supply). I was thinking of using it in my unfinished project with the PCM1794 because it has a large Ia.
Anyway... whoever wants to make a Miro DAC with tubes it can - it will sounnd great.
What specific DAC model of that price You have had opportunity to listen in Your home system?
It is huge difference in internal parameters of theese 2 tubes 🙂
used with output transformer or any reactive load. 6E5 have around 1K against 6N6 of more than 2K of Ri.
That is figure of merit for the amount of Primary inductance...
...
Imagine (calculate) how big amount of inductance needed for the 6N6P
for good bass range AND phase shift caused by LF filter
.
Some basiic transfer measurements maybe?
Again - in Your system
And in the same time listening all of the dacs to compare - or in the longer time interval?
Maybe some picture to ilustrate listenig environement 😵 ?
...
Did You aware that outcome of Yours "wiping floor" and "10000" narrative is making huge damage to this and similar topics?

Zoran please, it is clear and we don't need to talk about it. I already mentioned that I said it wrong. I was planning something with the 6E5P because I have two pairs of them. So there was confusion through my fault. It's hard to make anything stereo with one 6E5P. And in the photo there is one amplifier tube, the other is the anode voltage stabilizer.
I have nothing more to talk with you about. It's not worth it. Ignore list...🙁
Thanks

I didnt want to talk - just mentioned in one row. If it is too much then sorry. You actually replied with numerous times more words - again irrelevant.
I just ask for some 10 seconds simple measurements of transfer, but again if it is too much to ask - sorry.

I just dont see the point of putting pictures only. Without some schematic and very simple measurements - against full-mouth "sound explanations"
.
It is simply somehow, for me, against good practice and tradition on this forum.
It's not my device, so I can't add anything. I only had that device for listening. I thought about that option as well, then gave up.
It's much easier for me to buy a pair of SS3601 and put them on the Miro PCB. And by the way, I like the sound of the SS3601 better. That's why we organize these meatings, so that we have a reference for what to do, so that we don't wander.

I just mentioned a minute set up simple transfer comes usually with phase... Not any science fiction measurement.
Not even simple FFT for another 10 seconds measurements when set up already done...
.
And some schematic with values if available.
Just like the schematic and PCB-s for the devices that someone else did and without it test devices could not be made...
Maybe someone else would like to try?
.
Instead of this feedback was a science fiction / philosophic answers... Maybe not fair?
For the Tech-Audio forum, this part of technology is also from importance?
🤐
There are many forums not considering technical things, but subjective aspects and personal listening experiences only.
And that is OK too

Music is not sine wave but rather patterns, similar to pictures but taken with ears, measured or determined by brain. Details in patterns are really difficult to specify with instruments.
Take the very sharp image in cold colors and compare it with smoother image in warmer colors. What will brain select as better or consider as more acceptable? What is objectivity here? Someone prefers RAW images, someone likes images passed through various filters, someone likes pictures from old SLR cameras, someone likes classic film. Similar is music. I prefer sound without digital filters. Digital filters have always tired me out and that's why I'll never be satisfied with delta-sigma and I'm glad I'm not alone 😛 🤣😍

If not deaf and want it easy, you will not be disapointed with the conf I proposed few pages ago with porn pics which propose feedback loop precise resistor reference, r-core traffo (since the beginning in this ,thread, rcore makes a great job for such nos dac), precise ref cap an aop and how to layout it as a trade off with dil8 or with @Vunce hack on the smd oap pcb.
Of course there are many implementation possibilities with more hassle and also many others with more colored parts 😉. For the guy wanting some listening confort, cmos or jfet nowadays oap are winners when some patience and care on the passive parts choice related to the rest on your hifi.
Edit : I do not use mkp classic can but they bring a certain smoothness that is confortable and easy to listen to in the oap decoupling stage (tip)
