  1. There are a lot of SD players. I built one from a SD trans 384 board and it sounds better than my Innuos Zenith II but it such a pain to know on which card is which album that I never use it now! So that issue does not disappear if you pay 180x for it!
  2. Its not quite wood but "panzerholz" a significantly compressed beechwood ply. It should increase the material cost by 200$ and the cost of a router bit.
  3. never liked Wilson, had much more respect for TAD even if they are not the newest thing
  4. I am very happy that Purifi is also considering DIY with their modules. As amp technology is advancing to very small distortion levels it may be more interesting to focus on loudspeaker distortion. Purifi shows a mid woofer and claim it is designed to reduce driver distortion. The surround has an interesting shape: half rolled forward and half back. A rolled forward surround distorts with large movement forward (and rolled back the reverse) so does this shape really remove this distortion? They also claim low magnetic distortion. Is this an iron less design?
  5. in my previous house here in California I had an ufer ground (foundation) and an additional grounding rod and it worked fine but I started to get problems over the years of extreme drought. Just watering around the foundation (not so easy with all that water restrictions) made it a little better. So ground with low resistance is what I am trying to achieve in my next house. Still wandering what is the best method. Multiple spaced ground rods (connected by high gauge wire)? Lot of rocks in the ground may make that difficult.
  6. why not "condition" the offerers? I had a simple filter parallel to my fridge and that of course did not limit the power to my audio system and all my computer stuff had its own cheap filter. In my present (intermediary) rental none of that is happening but I would like to implement that approach again!
  7. I just read some of this video got blocked https://www.analogplanet.com/content/high-end-munich-2019-day-two-coverage—even-more-turntables until sound got deleted. The music industry is your friend!
  8. Devialet has a topology which makes the filtering after the the class D stage unnecessary.
  9. I think filtering is the main issue with class D to completely surpass classical amp topologies and obviously higher frequencies are making filters easier. I am using class D to drive my woofers and therefore filter design is less of an issue but even then I can hear differences between different designs preferring Anaview AMS over Hypex. I would be very interested to try these Purifi modules!
  10. I wonder if RPG room sizer can simulate the shape of your room's ceiling (likely the most acoustically problematic part). I used several softwares to predict room acoustics recently mostly Room EQ Wizard (no Windows required) but all allow only for parallel surfaces.
  11. I am using my Zenith II with Roon and Qobuz and like everyone else I think it sounds very good. I am using it as a Roon core with my Devialet D250 core (everything is now called core) and I can connect via USB or ethernet (Devialet AIR). Sound wise the different connections sound slightly different but both good but AIR is more convenient as it allows volume control via Roon. I was waiting for Innuos own user interface but they have to come up with something special to best Roon. If I compare local file (CD rips or downloads) with Qobuz I find the local one clearly superior but I really appreciate Qobuz's catalog!
  12. For years I thought that my CD transport sounded better than any other digital source (except my SDtrans 384) but after I got a Zenith II I haver not used it at all as the sound quality is significant better with rips than CDs played directly. The only aspect I miss was the UI of the CD transport, i.e. getting up from my chair and looking in my shelf for a specific CD (of course I like a living room less cluttered with CDs). Even with Roon finding the album I want to play is like looking through lists or trying to remember the name and spelling of an artist one has not revisited for some time. Roon has sometimes some background info but every CD had liner notes.
  13. It is about time difference of direct sound and reflected sound. 6 feet traveling difference (also applies to sides) is the minimum for our auditory system not to confuse direct with reflected so a 3 feet wall distance gives 6 feet back and forth but more if quite better!
  14. Why not use BX I.e. metal clad wires instead of NM (Romex). Should have much better noise rejection as it is twisted and screened and rodent proof. I have to renovate my house which still has a lot of post (knob) and tube wiring and that is terrible considering safety and electrical noise issues (single spaced wires). At least for my listening room I am planning 10 or 8 awg (not much cost more if one does not get audiophile grade).
