  1. The link in my Sig has other graphs including an un-smoothed version of the full sweep previously posted. Unfortunately thats the best I have on hand at the moment. I've never considered shrinking the vertical scale but will keep it in mind next time I take some measurements. The un-smoothed measurement shows the as the Blue Line being all channels combined and then the Red/Green lines being just Left or Right main with the paired Left or Right sub. In any case, I can say its pretty smooth either way I shrink the scale but thanks for the suggestion and I will keep it in mind next go round.
  2. I honestly can't think of any Audiophile recordings that I own other than something along the lines of Pink Floyd DSOM assuming that would fall into this category? If were talking about the Chesky or Channel Classics type recordings then I definitely don't own any of those. What I do do though is find the best recording version of the Bands/Albums I do like. In fact, I go out of my way to aquire those versions whenever possible but not sure if this counts as Audiophile recordings or not. Given my taste in music falls mostly in the Hair Metal and Trance genres I would think it doesn't qualify 😀
  3. Adding a few more I've come to rely on over the years since my last posting in this thread: Mariah Carey - Mariah Carey Nine Inch Nails - Pretty Hate Machine Sade - Diamond Life Don Dokken -Up From The Ashes Gatecrasher Global SoundSystem (Y2K)
  4. For the time being, I've settled on a curve that has a 2db bump at 20hz and is flat to 1khz and then ends at -10db down at 20khz in my room which has zero physical treatments and is quite large and open. This seems to work pretty well so far but at some point I may reduce the correction a touch to let the main speakers return a little more of their natural sound which is a bit more realistic sounding than the current curve with room correction in place. All in all, I like the corrected room much better as a whole but some may find it on the duller side. Target curve shown in Red via Audiolense...Actual measured in room response shown via multi colored REQW curve.
  5. Mr speakers Alpha Prime. I own them and they are impressive at home when powered by Benchmark DAC3 and on the move when powered by Pono Player
  6. FWIW, USB 2.0 is said to max out around 60 (MBps) and USB 3.0 is said to max out around 640 (MBps) both of which are waaay beyond what any audio system is likely to ever ask for under any condition. I believe there is somewhat of a standard in place in packet size for USB when streaming audio that is around 1MB chunks but depending on the software used you may be able to tweak that number. As an example, if memory serves me correctly, MPD Voyage Linux allows you to alter these values but it may have no useful outcome since the USB device itself usually tells the OS what it is capable of receiving in terms of data packets via the driver. I did a similar series of tests back in the day for Ethernet streaming via hard wire/wireless to determine what connection speed was required based on various Bit/Sample Rate files being streamed. This was mostly done out of curiosity for wireless bandwidth requirements. Here is a link to that Blog post if your interested in seeing the info. Unfortunately the pics/graphics have been stripped out over the years but most of the content is still intact. It appears I can't edit that Blog anymore otherwise I would add the graphics back.
  7. Has anyone done a deep dive into how to reduce DPC Latency on a Windows based music server and if so what have you uncovered? This of course is for those using USB based connectivity to the DAC. I'm curious if the PCIe based USB Cards offer any better performance then say the baked in USB Ports on a given system. It seems that most of this probably boils down to the quality of the driver, Horsepower of the system itself and tweaks to the OS but I've yet to see a good guide on reducing such latency, especially with Windows 10 that say anything more than try to disable various devices in Win Device Manager. I have gone thru this exercise and it made no real difference. Disabling the NIC Card is not an option which is something typically mentioned. I do wonder how much better a Thunderbolt3 based system would fare in comparison since the drivers involved for Thunderbolt3 are very close to that of a PCIe based driver or so I've read. Some of the old school tools out there no longer work with Win10 and report false readings such as DPC Latency Checker from Thesycon. My Intel NUC is no slouch in terms of horsepower but still reports unimpressive numbers when checked with the latency tools that do work with Win10 such as LatencyMon by Resplendence. The issue of course with this latency is resulting drop outs and other nasty things that can be very annoying. The only hope I'm holding on to at this stage is for Thunderbolt3 being much better or for more then the one or two companies that exist today who offer Ethernet based multi-channel connectivity (ie..Horus,Metric Halo8 3D).
  8. Its a Black Sabbath kind of evening
  9. Here's a few more to add to the collection IMO of course Vandersteen Audio (Pretty much all of them) but here is the Model 7 Linkwitz Audio (Pretty much all of them) but this one is real special Thats it for now. I've got many in my head but the wine is clouding my memory of the brands right now
  10. Nice article. I'm a pretty big fan of Tears for Fears also. Just figured I'd post up this info for anyone looking for a quality Greatest Hits Album of theirs. This one is my goto with nice DR numbers to show is Audiophile worthiness in terms of SQ.
