It is in no way an "alternative" to a Merging Hapi. The two are different products for different markets. For our market, and for our intentions, the MiniDSP is a vastly superior product.
The Hapi is a pro audio DAC/ADC/interface with no built-in DSP. Its real strength is its robustness, flexibility, and audio over IP (AOIP). It has Ravenna, but newer versions also support Dante. It can do things that the MiniDSP can only dream of - you can gang together a dozen of these things and get hundreds of DAC channels, it will work with any Dante/Ravenna device (and there are hundreds of them!), you can network many of them and supply audio to a whole stadium or airport, you can route any input to any output. And of course, it has DSD capabilities for those who believe in DSD. But very few of these features are relevant for us home users. To get it to work for home DSP, you need to add a PC. If you want to do something simple, let's say, switch from listening to streaming to listening to your turntable, you have to reconfigure the routing before you can listen. The weakness isn't the device itself, it's the PC that you have to add to make it a functional DSP unit. The other weakness is the complexity of ANEMAN (Merging's network audio manager). When you get it to work, it's rock solid. But the problem is getting the damned thing to work.
The MiniDSP is a device designed from the ground up for our market. It does not have many of the Hapi features, but that's because we do not need them. Switching inputs from streaming to ADC would probably be as simple as pushing a button on a remote. There is no need to keep a PC in the signal chain, you can use any consumer electronics that you like. And no PC means no PC related problems. Every time my PC prompts me to update Windows, I have that little bit of anxiety that my audio chain will be broken after it reboots. No such anxiety with a MiniDSP.
Merging's customer support is excellent. I know from first hand experience. MiniDSP is good, but nowhere close. They'll point you to their forums where you can get some help. It's better than nothing, but it's not as good as being able to exchange emails with an actual human who does not give you canned AI responses. If you are building a studio or have a large audio project, Merging is second to none. But we aren't doing that, so in our case the convenience features of MiniDSP wins.
Thank you
@Keith_W for your thoughts and detailed descriptions!
At least in my case which you know quite well, however, 99.5 % of my music listening enjoyments is just listening to my local SSD digital music library tracks consists of ripped CDs (90 %,
ca. 3,600 discs, photo ref.
here), other download-purchased tracks, some video clips, as well as
ca. 500 digitized vinyl LPs (digital music library organization, ref.
here). I seldom listen-to/watch streaming services or TV channels even though I can do these in multichannel my audio-visual setup.
Consequently, I like to stick to my present almost established PC(Windows)-DSP-based multichannel multi-SP-driver multi-amplifier full-active stereo audio setup (latest system ref.
here and
here). This means I shall stick to simple multichannel DAC units like OKTO DAC8PRO which I use now.
Presently, my system is 2-way 10-channel with L&R subwoofer, woofer, midrange, tweeter and super-tweeter; since I use 8-Ch DAC8PRO, now tweeter and super-tweeter are fed CH-7(L)+Ch-8(R) of DAC8PRO and I use BEHRINGER DS2800 XLR splitter/distributor to drive tweeter and super-tweeter by independent two amplifiers (ref.
here). This is one of the main reasons for my demand of 12-Ch to 16-Ch pure multichannel DAC unit capable of up to 192 kHz 24-bit with balanced XLR outs, just like
@Kal Rubinson is doing with
Merging HAPI + two of DA8/DA8P DAC board.
Furthermore, recently I become much interested in the robust and wide-bandwidth ethernet audio protocols including AEC67, Dante, Diretta, Ravenna,
etc.
In my powerful Xeon-CPU test Windows workstation upstairs, I have already installed Dante, Diretta, Ravenna ASIO-LAN drivers (to be used in dedicated IPv6 closed ethernet LAN chain with added 2-port 5 GB LAN card) and confirmed that JRiver MC, VB-MATRIX and EKIO recognize these ASIO-LAN drivers properly. At present, however, I have no multichannel DAC unit having these LAN-connection capabilities...
