That's a shame--at least nobody was hurt. I liked their DAC chip in my Topping DX-3 Pro DAC/headphone amp.

Just a friendly warning, you'll be best to stay out of the comments section there IMO.

Usually semiconductor manufacturers have a second source foundry or partner that runs the same/similar process. Let's hope AKM did and they can run the same designs there.

I was hoping to pick up a Topping DAC soon, but I have just been fascinated by my new Analog rig.

I think they will just get a new FAB, so we'll just have to wait.

RE: I've got TEAC UD-503 with a slightly older version of the AKM chipset, posted on November 4, 2020 at 09:54:59
in a dual mono set-up and it's really, really good.

The TEAC had some trickle-down form Esoteric, and it shows. The 505 was announced and I've seen a few, but not sure where TEAC (or Esoteric) is going after the parent (Gibson) went bust.

Lead time from Amazon seems long, as it was when I was shopping for the Topping D90. I ordered mine from Apos Audio [great customer service, BTW] and it arrived in about a week.

P.S. I think the Denafrips Ares II would be a direct competitor to the Topping D90. Based on price in USD they are very close. Topping offers more flexibility and features, and it sounds great, but I wonder how the Ares II compares sonically.

The percentage of humans that seem to be idiots likely remains stable
among audiophiles, so ANY chat board on Earth must have them.

How could audio chat boards be immune?

That one obviously isn't, nor is this one.

...I'll have to view it again. If I recall, the main advantage of the Ares II according to the reviewer was its soundstage. I'm not lacking for soundstage with my tube amp in the large basement but its almost non-existent in my smallish home office.

I'd love to try the Ares II but reluctant to spend money on yet another DAC ;-). Maybe once we have the basement finished.

Thanks for the link. Like I said, I saw that review once but I'll go back and pick through the details.

There are idiots everywhere, not the least on audio forums.

Incidentally my cynicism of the human race has never sunk lower since observing the number of Americans who voted again for the pathological narcissist and liar who is, but hopefully won't much longer be, POTUS.

Versus the Topping DX7s I was using just before, the D90 is very similar perhaps with a tiny bit more resolution.

I like the D90 but then I'm a transparency/resolution fanatic when I comes to not only DACs but equipment in general.

Does the D90 lack "air"? I can't compare it with the Denafrips, but I don't find it lacking in "air" if by that one means transparency and fine detail -- on the contrary. I owned an R2R DAC years ago but in fairness I wouldn't assume it was equal quality to modern DACs.

I have used the D90 ahead of my Freya + in Tube Mode. All I can say is that I rarely used Tube mode but instead mostly Passive Mode. Here let me be blunt: I regard the "air", "soundstage", and "holographic" effect of tubes to be "fake". I find it detracts significantly from the sound in case of Classical music, though when I listen to Jazz and other mainly solo voice and instrumental music, the effect is generally pleasing.

as it is a recreation of a 'live' performance.

Plan for it to sink a bit lower with their reaction to the (fingers-still-crossed loss)
before it bottoms out.

We must all hang in there.

when I go the symphony, I do hear soundstaging, air and get a holographic sense of being in a large space. Triangles and upper wind tend to "float" above the orchestra.

I don't find the sense of realism "detracting" from the performance in any way. ;)

True, BUT you will never achieve full realism, so you have to pick your preferences ;-)

but the characteristics Feanor finds *distracting* are exactly what I hear at every symphony performance I've attended!

Do find the natural sense of air and soundstaging found with live, unamplified music "fake"?

Even in a small room, the sound of wifey's baby grand has that elusive quality of live music.

The Topping D90 doesn't lack air or soundstage in my larger system, but some reviewers have concluded the Denafrips Ares II to produces more of it. My point is that it would be interesting to compare them side by side in my systems since they are almost identically priced. Sub $1000 DACs have come a long way in the past few years.

So what I hear from a clean s/s system given I'm listening to a recording, is more genuine transparency, air, and soundstage than I get listening through tubes.

Grant me than when you are listening to tube playback you too are listening to a recording. You are entitled to you preferences of course, but the tube effects are artifacts caused by distortion -- of course I'm not able to judge your VTL MB-450 Signatures never having hear them as a specific instance of tubes.

So you do hear T,A and S. Good start!

What constitutes "more genuine"? I'm a classical enthusiast as well. I'm curious as to what you hear as compared with live.

Note that my ARC preamp is a 6H30/JFET hybrid.

I have been working with Semiconductor manufacturing equipment since 1982, a lot of that time in fabs, repairing equipment, and later selling it. In all those years I have never heard of a fire as bad as what is described in the article.

Semiconductor fabs use so many dangerous chemicals and gasses and the damage from even a small fire is severe. In a cleanroom, just cleaning up the environment after a fire can take months. Getting all the equipment re-qualified, longer still.

Semiconductor equipment is extremely expensive. Just from the one picture, I would guess this was an old fab, maybe the 80's or 90's and the equipment was probably fully paid off. Given how bad the fire was, I would guess it is all destroyed so they would likely need at minimum a hundred million just to replace the facilities and production equipment and that would be for the least sophisticated equipment for a low volume fab. New state of the art fabs cost 5-10 billion.

Companies can't get loans for fabs unless they are underwritten and almost all are insured by factory Mutual who also has their own safety standards that companies must comply with in order to get insurance. I would not be surprised if they would not insure this company just because of this issue.

The most likely outcome here is that the company will get their IC's made by a foundry. There are Foundries that can make anything from the simplest to the most complex IC's so if there is a market for the product and the company isn't driven into bankruptcy by losses from the fire, they should not have any problems producing chips.

Both my Metric Halo boxes use them (AKM 4393 & AKM 4395). Admirable performance in the Metric Halo implementation. Never had to consider these chips may have a shelf life but I would imagine they'll probably outlast me....

I worked in IT in a wafer fab (Siltronic) in Portland for 4 years. Fire
did not seem to be high on the list of hazards of working there. Chemical
spills/leaks, earthquakes, and ash fallout from local volcanoes (Mt. St.
Helens, and others) were the principle worries, as I recall. Apparently
chip fabs have a lot more and different worries. I would guess TSMC can
produce anything AKM might need produced in order to meet delivery
requirements. (Even Intel is starting to outsource to TSMC, if you can
believe that ...).

The Denon receiver I use as the home theater controller/preamp for my main system uses the AKM AK4458VN and I like it very much. I think my Oppo Blu-Ray/DVD player uses AKM, too. I hope they recover swiftly.
