If the latter is the case and we have to believe our ears, the external reference clock apparently also has some short term impact?

Thanks! Does that mean that every solution with an external reference 10 MHz clock is suboptimal, even with the Mutec Ref10, Cybershaft or Afterdark clocks that people are raving about? (In my setup the Afterdark had a considerable positive impact connected to a Mutec MC-3+ USB.)

Interesting indeed. I guess the yen sign is actualy Chinese currency? Approx. $ 150 in that case? Can someone explain why the external 10 MHz reference clock option is not optimal? I happen to have one I do not use (Aune XC1) as it was replaced by an Afterdark Emperor Double Crown. I cannot tell from the pictures whether the 10 MHz connection is 50 or 75 Ohm, anyone knows? Thanks @seeteeyou for your research -- thorough as ever :-)

Interesting! Alas the link does not work for me...

After doing some reading and YouTube watching I now suspect another possible important benefit of the setup with only one DAC and one stereo output, i.e. SHD Studio --> digital out 1 --> DAC1 --> preamp --> amp --> mains + speaker level into subs Vanilla Dirac Live deals with one speaker at the time. Meaning that it cannot guarantee proper treatment of f.i. Mains-L + Sub-L combined as the speaker and sub overlap in terms of frequencies but are Dirac-treated separately. Dirac has recently issued a 'Bass Control' plugin (see in-depth video linked below) to deal with that, but I do not think this can be used on MiniDSP products (yet). The above single-DAC setup already deals with this problem by having Dirac treat Mains-L + Sub-L as one speaker, enabling an improved overal resulting curve. And I expect this to make more of an impact than time alignment of speakers and subs (which is not possible with the one-DAC setup) especially when the subs are close to the speakers as they are in my case.

Thanks @R1200CL! The SHD Studio + measurement mic are on their way. I assume that the second setup with one DAC will also work with SHD/Dirac/DSP but with only one digital stereo signal out: (L) Mains-L + Sub-L merged and (R) Mains-R + Sub-R merged. This will still give some control over the total curve but of course not so much as with two stereo channels (1L) Mains-L, (1R) Mains-R; (2L) Sub-L, (2R) Sub-R. In the latter setup I will be able f.i. to time-delay a sub that is close to the listening position, which will not work in the 1st setup. I will try both setups and report back... which does not mean that additional comments/suggestions are not welcome :-)

Linked where? Can you share the link please?

No. It is on order. TMI for this room correction/DSP newbie? But I will take some time to read the thread...

A newbie here considering to use Dirac for the first time, f.i. with a MiniDSP SHD Studio with digital ins and outs and (an) external DAC(s). The setup is 2.2 with TAD ME1 mains and KEF KC62 subs. For the latter I can choose between low (line) and high (speaker) level inputs. Before I take the plunge: I am pretty sure Dirac will work in this setup: SHD Studio --> digital out 1 --> DAC1 --> preamp --> amp --> mains SHD Studio --> digital out 2 --> DAC2 --> line into subs However I am considering SHD Studio --> digital out 1 --> DAC1 --> preamp --> amp --> mains + speaker level into subs The latter setup has the advantage of needing only one DAC, less connections and possibly better integration as the mains and subs are driven by the same amp (Reimyo KAP-777). Will Dirac still work well in this setup? I would guess it will for frequency and EQ but no longer for timing corrections?

No. The thing is that I may not be able to use the high level Speakon cables, as the subwoofer does not allow for them. Hence my question.

For that an external active crossover could be used I guess, although I am reluctant to add yet another component.

Thanks Kai, trying to understand... In terms of bass roll-off the use of two of these converters would not be any different than sending the line level signal from an additional full (i.e. not one marked 'sub') line output on the preamp -- if that would be available. And bass roll-off would be done by the sub's active amp, correct?

Because my amp combo (The Truth preamp and Reimyo KAP-777) are here to stay for a while and do not have an additional line out. I have tried with an RCA Y splitter but this degraded the overall SQ, perhaps related to impedances. Fyi, speakers are TAD ME1.

To replace my two REL t5's I am now looking at a few 10 and 12 inch subs. Most of the ones I would prefer and are within budget seem to lack a high end (speaker cables) input. For instance Swedish XTZ dropped these for their higher end models. When I asked them they replied "You should be able to use simple high-level to low-level converters as that is basically the same circuitry that is used in amps with the same functionality. Unfortunately I don't have a concrete example of a converter to use. My suggestion is that you check with stores that have them and check online forums for tips on which specific converters have the best sound quality etc." (Of course the amp he mentions is the active amp in the sub.) Does anyone have experience with such line output converters (often used for car audio) in a home audio setup, or any recommendations?

Can you send me a brief 1536 track?
