So always say 'I like it more' don't say 'it sounds better'. Many things combine to the pleasure of music listening and SQ is just one of them. And our hearing acuity changes (sometimes drastically) over the course of a day.

I don't think that this makes sense. It is too specialized, esp.
at the price.

Prices of used SAs have fallen deeply.
Or take a look at a Signal Hound, for example.

Or a Red Pitaya. Member w5jag (thread "No RF Gear Here?")
has one and uses it. He might tell his experiences.
It can work also as a signal generator, VNA or SDR.

Two Red Pitayas have all the hardware to make a Timpod-workalike.
It's just that someone must volunteer to write the firmware
It already runs Linux on its ARM. The SDR firmware can probably
be recycled for this purpose.

The Tinysa seems to be a pretty good spectrum analyzer for around $100. Not SOTA but really small, battery powered and should be useful for emi.

Oh goodness, you are following the 1995 internet argument playbook. Please come and join the 21st century.

George,

Don't forget that someone here has stated the British are culinary masters.
Taste impressions but not sound impressions.

Hello Andrea,
So true i rather trust someone who prefers coffee and not tea.

We all should sit back and relax until Ian distributes 50? boards for FREE to the people who already own Andrea's solution. If it is better they will pay the 10 S production cost if not they will have to send it to a new reviewer.
After a few weeks everyone can decide themselves what to do.
Greetings, Eduard

Hi Eduard,

no problem, I also would get Ian's sine to square converter board to try it in my system.

We have designed the STS board fit Ian's FIFO devices and the FSDO board for those who need to distribute the clock or to switch between the two sample rate families clock.

Then, as I said several times, our goal is designing the whole audio system for ourselves to reach the best performance as possible (I have called it the Top version).

Well, for our top system we are designing a different sine to square converter, much more complex and expensive.
If it will work as we expected we will not use the STS, nor the FSDO and neither Ian's board.

Andrea
