No harm at all.
I had too had thought about such a device - a universal programmable 3 way active amp - but I suspect that the commercial potential would be very limited.
I guess not much as far as the commercial potential is concerned, and without any insight into such approaches, or actual benefits to be gained from them,my own personal preference is to try to AVOID crossover points and filters as much as possible in the first place?
That is imho one of the benefits of both good planar or electrostatic headphones AND speakers. Almost seamless reproduction from top to bottom. The more drivers involved the more problems to solve imho.
I may have mentioned it before but one of the most transparent speakers I have ever auditioned is still the almost, but not quite, full range ,ML electrostatic speaker XL ART which had no crossover point at all !
But it needed a subwoofer for really deep reaching bass intruments like double bass and organ.
Big electrostatic panels handled everything from above 20khz down to around 50hz.
Not quite enough for BIG Bach organ works like BWV 565 or Also Sprach Zarathustra and such ,but with a subwoofer added for such works a lot of good music could be played without any crossover filters needed.
Imho very few conventional speakers with up to three crossover points can compare with the transparency and effortless reproduction and lifelike soundstage of an electrostatic speaker with acoustic music.
My own compromise electrostatic speakers have one crossover point between electrostatic panels down to around 250hz and from there passive conventional bass drivers down to 32hz.
More modern MLs than mine use a class D active bass but to my ears do not sound better in the lower regions than old school passive ones. What was you impression on Romaz´s electrostatic 15A speakers in that respect?
A big problem with electrostatic speakers and bass is that the panels would have to be HUGE for really clean deep bass.
There are some by other makers ,but way too expensive for me, and even the XL ART is much more expensive than I am willing to pay for it new.
But I am keeping an eye out for second hand XL ART speakers. So far no luck. But there is currently a Dave for sale at a price that actually tempts me a bit. But only a bit. still not enough to bite. I am more interested in hearing what your upcoming Mscaler x will bring to the table SQ wise.
Meanwhile my current old ML Sequel II sound better and more transparent than many much more expensive conventional multi driver based speakers to me even with my humble Qutest Mscaler combo .
The benefits with the Sequel II being a very stable , pinpoint, quite big and transparent soundstage with reasonably good depth too. Although sometimes soundstage depth is where even a well recorded LP can still compete with Qutest/Mscaler imho.
And over most of the range the MLs also have low distortion levels until the conventional bass takes over from around 250hz.
I listen almost exclusively to unamplified acoustic instrumental music and the human voice both Western Classical and Asian and World music. Very rarely Western Pop genres music.
I never listen to RAP or HIP HOP or EDM!
And while I am on the "non grata" subject of musical taste , let me confess in my younger days ,yes I did go to the Disco sometimes, but I NEVER went there for the music , always played at ear damaging levels, but for entirely different reasons. And I always used both hearing protection and other protection when striking lucky!
Since my mid-teens ages ago,when I listen to music I do that ,ONLY that, and never anything else while doing so.
And although I also stream quite a lot of World Music via Youtube these days via Mscaler with its good SQ but annoying latency which forces me to close my eyes instead of watching, for example, Khatia Buniatishvili play so well. And I prefer to listen to whole works before turning my attention to other good music.
It was a bit surprising when I heard DAVE /Blu 2 via your laptop at Canjam in Singapore 2018 to see how random your music selection was.
This may sound very snobbish to many here , but random selection and shuffle is for kids imho.
Music is my ONE AND ONLY religion.
My musical attention span also extends for much longer than the average 4-5 minutes pop track demands, or like some old Rockers? here who apparently even use a Dave to listen to the Beatles or Johhny Cash in mono via Quad electrostatic speakers!
Nothing against the Beatles, but Johnny Cash is definitely NOT" my cup of tea".
I often listen to at least a whole act or even an entire Opera at night before going to sleep.
Wonderful way to wind down after a day to dive deep into a Mozart or Handel Opera for example .
Other nights I may choose an Indian Raga by Anoushka Shankar to wind down to.
Sorry about yet another VERY long winded and NOT politically correct post from CC.
PS.
I liked your first? attempt at recording unamplified acoustic instruments in a real venue without multimiking.
But I am still waiting for an answer from you regarding which ADC you actually used and what resolution the very short snippet was recorded at?
And I would also like to know how you feel about doing binaural recordings instead of resorting to crossfeed compromises for headphone listening?
