In Reply to: RE: DACs, DACs, DACs!!!!!!! ???? Why are there so few good ADCs? posted by John Elison on November 16, 2016 at 18:03:50
I am interested in getting one - to play 2Ch analogue recordings through in real time.
And run that output into a room DSP, crossover and delay box, and absolute polarity switching. Say from Mini-DSP with a nice big PSU.
I doubt I'll be buying an ADC before a year, or even two, is out.
I will be seeing how I go with swarm subs from 150Hz down (3rd order Lpass) and 1/3rd octave analogue Eqr's for the bass only, for the near future.
Instead I will be buying more recordings, and might buy an SACD player for the sound system. I'll be installing a spare pr of speakers for rear sound, using derived L-R signal plus differential delay. Until / If I have a lot of MCh. music.
The HT system in the family-room kitchen might get a universal MCh AV player, and sooner than the ADC and DSP kit.

if you are going to do DSP.
Perhaps checkout DEQX a one-box ADC + speaker DSP correction + room DSP correction. And they are Australian - how can you not like that combination?

And difficult and slow to set-up.[I have a friend who has had a used one for ages - and still hasn't Dsp'd the room response with it. !!?! yes!]
Especially considering that it seems that the right Mini-DSP box / boxes can do what I want for far less. Even with the price of RTA SW for my tablet, and a test signal source / test CD, and a suitable mike. I have a stand already.
Noting that I doubt I will be eq-ing the 63s much or at all, as they are dipoles,and won't be doing much in the bass. Even if their amps are being fed by a DSp/DAC output signal, I don't want to damage their impulse response with Eq.
The most I am likely to use is a slope-control ? > < to adjust the whole sound for over-bright or dull (old?!) recordings. And that might go in the analogue pre, if Mini-DSP's range can't meet that need.
Or there's D-Speakers latest room-eq device, which does have a slope control?
I Hope to learn a lot from the analogue 1/3rd octave Eq and Diy Swarm subs. There are three stages to that. All using 1/3rd octave eq per channel / even per bass source, when I can scrounge some more.
Stage 1? will use two pairs of the *Audiosphere 3s in an arc from and behind and back to the QUADs, *the speaker I bought instead of a pr of 57s back in the late 1970s. Plus another pair bought since. Two of which IME(&O) do a good enough job on 32ft organ pedal reeds with some room-gain. Their Fb being 38Hz with a QB3 slope. I won't be using the 20Hz sliders on them, but I will see if a touch of boost at 30Hz helps.
Stage 2 is when I add two sealed DIY (clam-shelled P-P driver) subs, and can give away the newer pair of Audiosphere 3s. It's then that I will need at least a fourth 1/3rd octave Eq.
Stage 3 is when I add two tall TL subs using a recent Martin King design and KEF B139s. And can use my original pair of 'sphere 3s for rear surround duty.
For an ADC - and DSP - I will still have to save up, so it will be a while. :-)!
