This looks like a lot of DSP for the money. It uses the same DSP chip as the MiniDSP. It lacks the ability to do biqaud filters and is limited to 24db/oct filter slopes.

Had at least two units brick, maybe three, can't remember. Luckily, someone else with the problem pm'd about the remote fixing the issue. Anyhow, have two of the 408 sitting in a pile of miscellaneous junk. If I want to play around with a crossover setting/notch/boost, and the minidsp are in use elsewhere, they might get used short term. IMO, the 408's only advantage over the minidsp is live adjustments, otherwise, the mini has no noise, sounds better, and the software is much more refined.
At first, PE was helpful. IIRC, PE did send me a free minidsp 2x4 to replace one of the bricked 408's.
Thanks for that feedback, KB.
I feel better for spending the money on the mini-dsp now than on the DA 408.
The low price just seemed too good to be true . . .

All the lumber in his chassis and home-brewed work led me to bread-boards.
Have you not ever stolen mamma's bread cutting board, drawn out a circuit schematic on it them pounded copper nails into it at all the connection points and soldered discrete electronic components upon it to test out a design?

THAT is bread-boarding . . .
I found this image online, I guess you can say this guy is bread-boarding
I don't know what's more alarming, the crazy expensive and massive Dueland components, or the fact that they're being connected with dollar store alligator leads. You'd think you'd have to use only the best platinum infused cobalt plated unobtainium for those.
They have a lot of clamping force for an alligator, and can use them with whatever banana leads I have lying around, or if you want a permanent connection just solder a wire in the banana hole.
Not DOTD, but a guy has listed 3 Focal Audiom 7NV2 Polyglass midranges for $200 on ebay. No association with the seller. Thought someone here may be interested.
I picked up a pair of 15uF 630V caps for the Rival/Viawave build I am currently buttoning up for about $33 shipped. Not too terrible if they are well within tolerance.

That is exactly how I bread boarded circuits in my college classes. It worked great and I learned a lot from that simple process. We even had a course where we had to manually lay out a 2 sided PCB (before the days of computer CAD programs that can easily do that now), mask it, etch it, and build the circuit. If it worked that was 70% of your course grade.

Worth the money, all I'll say.
Have you heard the Apple Probuds? A coworker thinks they 'should be better', but I'm betting not.

No, not much Apple stuff here.

Didn't Kornbread have his Dayton DSP unit brick?
I bought one awhile ago, good little unit I put mine in a case so the mess of wires are hidden.

KB - where did you purchase the audio project box/chassis?
I need one for two 3 channel Wondom amps and power supplies, yet . . .
? Did you mean hifiside?
My mistake - I am distracted with re-configurations tonight - yes, I guess this should have been directed at hifiside . . .
I think there were issues with noise or something with those?
They also lack digital inputs.
I could never get rid of the noise. Different receptacles, power strips, magnets, touching a ground wire from chassis to chassis.

I like it ^
That's what we used to call "bread-boarding".
No, those are printed circuit boards.
This is a bread board.
Weird mine has no noise. I have a no chassis MiniDSP that is noisy and no gain to it.

Dude, I still feel bad about that whole fiasco.

And he is using a drill on carpet that is probably his living room floor.
Must be a bachelor!
I ditched those kind of alligator leads a long time ago. Their resistance was shit.
Yep! very questionable connections with cheap-o alligators.
I try to use wago connectors where ever I need a temporary connection, but if I need an alligator I picked up these which are rather nice:

Hehehe "banana hole"....
I made a bunch of leads using heavy gators and 16awg wire. Much more better.
Mini grabber for me. We use them all the time at work.
Was the count three or four bad 408s? PE was fairly eager to figure it out at first, later they got a bit agitated and sent a minidsp for hush money.
Of three minidsp, one nude, none have any noise and that is with the cheapest wallworts I could find.

Now all of the sudden PE drops the price of their Class-D https://www.parts-express.com/Dayton-Audio-DTA-2.1BT2-100W-2.1-Class-D-Bluetooth-Amplifier-with-Sub-Frequency-Adjustment-300-3831 amp to pre silly pricing levels after having it priced at around $105+ for a while.
Its a good little amp and used to be on sale for $75 which was a steal.
I might change the name of this thread since it is pretty rare that PE DOTD has any real significance to our particular niche of DIY audio these days.
That being said, this seller on Fleabay has a bunch of OEM Clarity Caps for sale:
