Depends who you're asking. A random man off the street? A musician or audio producer? Your average Vogoner who posts in the Audio subforum? Personally I've been all 3 at different times, and all three would have a different perspective on all those questions.

I feel that I'm being somewhat led towards the sentiment that it's of limited value to compare recordings of very similar devices, because the differences are so minute that it doesn't really matter in practical terms anyway. An understandable sentiment and certainly true to a degree. I said as much about the Gravis Ultrasound in another thread this very day.

And in a way, that's actually why I asked for a comparison recording. Not because I doubt that this card is excellent, in the slightest. But because I believe it's scientifically important to quantify exactly how it's good - and yes, in niche quarters like these, it will be in fine detail!

Subjective claims such as "omg this is the greatest ISA soundcard ever!" need to be balanced in context with real world A/B comparisons, because if a random man off the street listens to clips A and B and concludes, "hmm these sound pretty much the same!" (or alternatively, "notably different, in ways X, Y and Z"), then they will know without any doubt where they stand on the matter. Without any need to rely upon, or be influenced by, Subjective Claim this or Subjective Claim that.

No, I don't mean to lead anyone toward any particular conclusion. I am simply providing additional recordings, and asking the questions. Whether any potential buyer thinks that this card is so close to the genuine part that there is no point in paying for "the real thing" at current prices, or that it was a waste of silicon if there is even a single bit in a single sample that is different, real recordings that can support that opinion are essential.

I haven't shared any opinions, nor suggested any conclusions; I am merely providing more data, and encouraging you to form and/or discuss yours.

That is good; thanks, it's interesting data. I must note that FM purism isn't my particular axe to grind, I'm of the opinion that several of the leading FM implementations all sound quite Fine & Good.

Your recording proves that there are differences in this case, and that those differences are audibly negligible. Which means different things to different people. To one, it may mean this is the perfect purchase, and to another, it may simply prove that it's essentially the same thing they already have several of.

Either way, data is appreciated, cheers.

From my recollection, at least with the CMI-8738, FM playback through the SPDIF output is an analog-to-digital signal. So, the recorded audio waveform will never look as good as pure digital like the YMF7x4 cards.

Beautiful achievement. This new sound card sounds perfect.
Forgive my late idea, but a PCMIDI MPU module in PC/104 format configurable via all available IRQs ports of the ISA Bus (3, 4, 5, 6, 7, 9, 10, 11, 12, 14, 15) could-be considered?
I have never seen one yet. And, what a 'utopia' to be able to mount several modules in a system.
Certainly for retrogaming, it is useless. But, for your next sound card design, you're going to have to create yet another new card format. That's a shame.
I wish him much success.

P.s.: It just lacks a digital audio out connector internally to be able to connect it to another sound card.

The MPU-401 module is already configurable for Ports 300h/330h and IRQ2/3/4 allowing for several MPU401 devices, though maybe not as many as you want.
