Minidsp SHD Review Updated (DSP, DAC & Streamer)

I don’t know how you define “a lot” but I’ve had one for four years and it definitely doesn’t meet my criteria. Especially when thinking about in terms of what little has been improved over the years, and not just the number of firmware revisions, many of which have been released to fix problems caused by previous editions.

At the end of the day, there’s simply no arguing that it’s been over a year since miniDSP offered SHD users anything, not even the most basic bug fixes, and that’s well below an acceptable standard.

I think they are just more of a hardware company than a software company. The software does just enough to sell the hardware, and doesn't really get features added subsequently. They're spending their engineering time building more hardware products.

This will ultimately get them into trouble because they are getting more competition (e.g. WiiM) that is far more agile and focussed on software.
 
Has anybody - confirmed - background data which implementation is used in the SHD?

I have no idea but Dave Reite has confirmed the SHD has the same intersample over clipping issues I observed with the 2x4HD. The ADSP-21489 datasheet says that the SRC uses the same core as the AD1896 and does NOT use internal processor resources, which I imagine is why we see still see intersample over clipping.

Somebody explain the issue they're running into. What exactly would I have to do to recreate it?
 
I noticed the lacking support for the SHD as well and did not like the non existing manufacturer feedback in the forum.

This was one of the reasons I finally sold it.
Not weighing an opinion on this statement, but there is literally nothing else like their products on the market. Even the 8 year old DDRC-88d has no competitor. There are not really a lot of digital crossovers out there that don't require a PC and have an FIR based room correction software option.
 
I had good experience from MiniDSP's support regarding my SHD. I had an issue from using too long of a USB extension cable that was not active. They were responsive, and told me what to do to fix it, which was re-flashing the firmware. (Nonetheless, they should have made it clear in big bold letters on the first page of the manual that you need an active USB extension cable if the included 2m extension cable is too short.)

On the other hand, I have a MCHStreamer kit (SPDIF I/O) I use with my raspberry Pi, and I have some issues on the input channels - not working at the highest specified sample rate and having some dropouts in the stream - short duration in the mS range. I reached out and support told me to test it using Windows. I did, then reported back the test results. After that, all I heard was crickets. I even sent a follow up email, for which I received no response. It's not a major issue for me because I am now connecting my WiiM to my Raspberry Pi via USB and only using the output channels of the MCHStreamer kit, and the output appears to be working well. So, I haven't bothered pestering them to try to get the input issues resolved.

That is - unfortunately - true. My current setup certainly is more capable in terms of settings and "doing everything technically right", however, at the cost of quite complicated operation. Only I can operate it, my partner is lost and uses the bluetooth speaker instead...

The Octo Dac8 and the latest firmware which allows implementing filters and delay for output channels might be a candidate for state-of-the-art excellence in a nice package, however, also seems to be very difficult to set up...

Are we - crying for such a device - so little people that development and software maintenance of such a product seems unattractive for suppliers? Maybe this is the case..

Can Okto8 do FIR? I thought it was just PEQ.
 
IIR PEQs / biquads as I understand it. No FIR.

Totally okay for room EQ IMO.

 
Very good news! If it works.
Unfortunately too late for me - sold my Minidsp SHD in the meantime due to no feedback from Minidsp on this issue.

Quite! There's a Beta available, but I'm waiting until some early adopters report success with the final release. Too much history of issues.
 
Excellent news!
 
IMO Minidsp should really change their policy of not announcing any developments at all. With someone like me as customers, this "no-communication" hurts their business. I cannot speak for others of course...

I like WiiMs policy of sharing feature development roadmaps much better.
 
It does work.
-2db pre-attenuation should be plenty, in most cases.
+2db on the master volume control then restores the same output level.

Dave.
 
Hi Dave, with "if it works" I refer to the issues an earlier firmware caused, where Minidsp moved the master volume prior to the ASRC which caused very loud static, cracks and pops for some users. Minidsp then pulled back this firmware...

Based on their comments in the newsletter they appear to have taken more time on this solution in order not to repeat that problem.
 
When did the newsletter go out? I haven’t seen it hit my inbox.
 
Odd, I haven’t received it. Last one I have is last year. Anything interesting in the newsletter (e.g. DLBC or ART support)? I’ve used miniDSP stuff since the OG 2x4 was a brand new product…but of late find myself underusing expensive AVPs when what I really want is DLBC processor.
