To Whomever Would Like to Assist:
In advance, I would like to extend my sincere appreciation to those who are willing to assist, and I apologize for my loquaciousness...
...and I certainly hope this is the most appropriate forum in which to post this inquiry...
An OLD audiophile here, (periodically seeking ever improving sound reproduction for 30+ years...
...), so, though my BASIC understanding of DSP is "OK", the plethora of available MiniDSP products here are a bit daunting if not confusing...
Essentially, I possess one connected audio system, with two output legs/chains, or, imagine a wishbone, or a river, in which a single river source splits into two rivers, (Both the signal sources and the D/A converter being the single river before it splits into two rivers, the digital signals of which are converted by a D/A converter, the analog signals then continuing their journeys downstream on the two separate rivers...
...
Signal Sources: (1) "Garden variety" OPPO digital disc player, output via standard digital SPDIF, terminated with BNC connector at D/A end,
(2) Computer USB to to Schiit Audio EITR, outputing to D/A connector via standard digital SPDIF interconnect...
D/A Converter: Schiit Audio Yggdrasil...which outputs the converted/analogue signal via balanced interconnects to my Primary/System (1),
as well as outputs the converted/analogue signal via unbalanced/single-ended interconnects to my secondary/System (2)
System (1):
Pre-amplifier: Schiit Audio Freya, (fully balanced and receiving the balanced signal output from the D/A converter--->balanced output to Marchand Electronics XM44-2 crossover, (Linkwitz-Riley, 24 dB/Oct. @ 60 Hz), which drives an Aragon 4004 amp., via single-ended outputs/inputs, which drives a pair of Lipinski Sound L-707 monitors. the active crossover also driving a pair of active, SVS subwoofers via single-ended outputs/inputs.
System (2):
Integrated amp.: Schiit Audio Ragnarok:, (receiving single-ended output from the D/A converter)---> the amplifier section driving a pair of Audience Audio Clairaudient 1+1 V2+ monitors, and via single-ended interconnects, feeding a pair of JL Audio Dominion D-108 subwoofers (possessing Linkwitz-Riley 24/dB/Oct. low-pass filters only, crossover set at approx. 60 Hz.).
I am very seriously considering upgrading my system(s) with a DSP device, and it appears that a MiniDSP box might be my best solution...and that the DDRC-22D might be the best of those solutions for me...Unless one can a case for the new MiniDSP SHD or SHD "Studio" units.
1. I VERY much like the sonic qualities of my Schiit Audio Yggdrasil D/A converter, and wish to do NOTHING that would adversely affect its qualities. THEREFORE might I assume that I must implement a MiniDSP unit upstream of my D/A converter...which then would suggest the DDRC-22D...(UNLESS I can be convinced that a MiniDSP unit installed downstream of my D/A converter would NOT adversely affect the sound of the system...I understand that the input/output design of the "22D" would allow me to channel both the digital disc player digital output AS WELL AS my computer digital output into/through the "22D"...
2. IDEALLY, I would love to possess a single DSP unit which could correct/compensate for frequency level and timing output issues in both my primary AND secondary stereo systems simultaneously, or at least possess the ability measure/store compensation algorithms for both systems and then simply select/enact the appropriate compensation algorithm for the stereo system to which I am listening at a given time.
However, if this is NOT possible, and I must select only one stereo system for which the DSP could measure/correct/compensate, is there a distinct advantage to selecting a stereo system with an active crossover, or would the MiniDSP unit do an equally good job compensating for both frequency and timing issues with either stereo system? (the secondary system currently lacks a dedicated/active x-over between the mini-monitors and the subwoofers, such that there is more overlap between the upward frequency output of the subs and downward freq. output of the monitors...Subwoofer drivers and forward monitor drivers are on the same plane relative to the listener, but subwoofers possess inherent15 millisecond group delay, and monitors are crossover-less design)...Can the "22D" compensate for the inherent 15 millisecond group delay in the subwoofers?...
2. Does MiniDSP manufacture an active crossover that is, (in terms of sonic qualities), at least the equivalent of the Marchand active x-over, which I could set at 60Hz./24 dB./Oct. ...?...
3. Are there any alternative options utilizing the MiniDSP units that would meet my needs, that would DO NO HARM to my audio chain/reproduction...(the 1+1 mini monitors are a crossover-less design, such that they generate well nigh NO phase issues within their output range, and I do not want to compromise THOSE inherent qualities..., nor do I want to compromise the sonic qualities possessed by the Yggdrasil D/A converter...)
I genuinely appreciate any and all input/suggestions/recommendations, and avidly look forward to your responses!
THANK YOU ALL.
Sincerely,
T.A. Kogstrom
