  1. Elektra by Bruce Botnick (known to use JBL M2) : RR1
  2. @Miska : What is the CHEAPEST CPU or bundled ready made machine to run the new EC modulators including ASDM7EC with Hi Res PCM and DSD sources with an output of mere DSD 128 ? Nota Bene : I use full range convolution you said you would do some testing back home after Christmas and I understand you had better to do I have to give back the MBAir I use to front Embedded with Audirvana and rather than looking for a replacement for that machine I'm considering fronting a new machine with my MBPr I'm not in the mood to purchase a new 256 capable DAC any time soon ; my main issue being room and furniture vibrating with some tracks I don't feel like spending on details (such as DAC capability) as long as I can't move
  3. Verve Reissues 24 192 : RR1 Columbia 24 44 Leonard Cohen : RR1
  4. SHM SACDs (Roxy Music) : RR1... sorry about that one ; though "DSD edited" by the same Japanese engineer, those "flat transfers from original UK tapes" seem to benefit from different convolutions on a case by case basis, almost track by track : it's more like trying to do the eQ work that hasn't been done than matching house curves we may implement to the conditions in which the art has been mastered since there hasn't be any mastering
  5. Blue Note remasters by Kevin Gray & Steve Hoffman on AP SACDs : RR1 24/192 by either Bernie Grundman or Alan Yoshida : JBL Synthesis in conjunction with MQA LP in HQP
  6. Mobile Fidelity (MFSL) SACDs : JBL Synthesis ECM : B & K
  7. There are several threads discussing target curves ; please let's keep this one tidy with simple sharing of our findings regarding Matching House Curves and Mastering. So yes there's a postulate that beyond subjectivity and idiosyncrasies of loudspeakers/room fit, there's a rational for using different curves so to get closer to the conditions in which the art was created/approved. The linked paper is an excellent read. I provide a picture of the curves I'm referring to (top to bottom : JBL Synthesis, Harman RR1, Bruel & Kjaer 1974, not theoretical but how I actually achieved them L + R with my room/system) ); please specify if you use different ones but let's not discuss their respective merits and motivations here. Once again, let's focus on matching, simple, straight to the point. However a few words about your criteria might be useful. AFAIC, it's mostly soundstage, how things fold together. The obvious more or less bass and sub bass criteria is not that operational and how vocals are infatuated or not tends to be the go/no go point for RR1 (above the 2 others between 160 and 500 Hz) vs either BK or Synthesis that are equivalent in that region. Also, the extra mids from 800 to 4 K of the Synthesis often act as an appealing reason to go Synthesis even if there's a touch too much bass, because of extra presence and delineation of soundstage, instruments and vocals separation. Next post is an example of how I suggest we populate this thread. If deemed necessary, precisions about decade of mastering or country could br added 17839.pdf
  8. Oddities I have played a lot recently with convolution ; I now consider I have better than ever and good enough frequency and times domains corrections to 3 popular targets. Consequences pertaining to HQP: I used to consider Minimum Phase filters as a cheapo way to tame and blur ; I now often find Linear Phase grudgy in comparison My DAC max output is DSD 128 and I find 352.8 convolutions to sound more dynamic less compressed even with n 48 sources while I understood from reading Miska that it should not matter, HQP taking care, and that max is the best I confirm I'm under the constantly confirmed impression over the years that I get a better imprint of convolution filters with the SAVE engine and thus wish it would be available in Matrix
  9. FYI, Left graphs show the results of convolving the Vector Average by an Impulse that smoothed it (big bass bump, straight line from 160 ; does not sound the best though has its charm if you like ultra analytical) Right graphs show the results of convolving the Vector Average by an Impulse applying B & K target curve to the non FDW scalar average (impulse I use) PS : sorry it got mixed up and names don't show : The Right graphs come first ; R phase shows the use of Pano shuffler in RePhase (ondulations)
  10. 3 perspectives on the 3 convolutions I will use from now on (JBL Synthesis, RR1, B & K ; psychoacoustic smoothing of L+R) All are smoothed, slope downward and have optimised step and impulse : none is bad whatever the recording and the target that might have been in use in the mastering room. Yet as dB differences show they don't sound alike and there are better convolution/mastering fits. If I had only one to pick it could be good ol' B & K that appear to have been a long time standard. But with Harman's promotion of RR1 and Synthesis they have their best fits too Maybe the most relevant view is the one bundling curves in 1 dB above 160 Hz : the obvious more or less bass and sub bass criteria is not that operational and how vocals are infatuated or not tends to be the go/no go point for RR1 (above the 2 others between 160 and 500 Hz) vs either BK or Synthesis that are equivalent in that region. Also, the extra mids from 800 to 4 K of the Synthesis often act as an appealing reason to go Synthesis even if there's a touch too much bass, because of extra presence and delineation of soundstage, instruments and vocals separation
  11. 3 weeks later : Parametric eQ to scalar NON FDW average of at least 10 sweep measures Should match MMM measure over 300 Hz, check eQ phase to FDW Vector Average look for tweeter peak in Impulse ; say it’s -37 ùs, set t offset in REW control before export, in Rephase, set phase offset 37 don t eq phase below 100 lightly till 300 or so do iterations from rew to rephase at 65536/96, no more, for faster results keep phase eQ, building RR1 on B&K, then Synthesis use pano shuffler presets in rephase enjoy 3 targets
