Nobsound springs - load range
@ryder Guess what, I am now on 2 footers with 1 spring in each.  Have you tried to stick with 3 units and put some weight on your DAC to reach the desired compression?  
Nobsound springs - load range
@tweak1 Well, I started pulling springs out late yesterday with 3 springs/ 3 Nobs under the Oppo first (decent improvement). The streamer/DAC I was talking about is also an Oppo105 (heavily modified: clock, improved XLR output stage, IEC inlet,... 
Nobsound springs - load range
All the calculations are a waste of time. I always get cautious when hearing such dogmatic statements. I would rather consider starting in the dark and doing erratic trial and error on all possible permutations of changes to different variables... 
Nobsound springs - load range
Thanks for the ideas for dampening the Nobsound springs, this works great. The PTFE tape (wrapped around each spring) did not have much effect in my case (However, I tried it only on my DAC). The dampening with the ear plugs however does magic, t... 
Nobsound springs - load range
@musicaddict I try to put in some physics about spring mass systems (have to dig a little since this is long ago since I had to deal with that in my engineering study). A spring extends or contracts in a linear relation with the force you are app... 
Nobsound springs - load range
@ryder yes I have the aluminum Nobsounds. I just remeasured, the gap unloaded is ~14mm, the gap with 1 spring and 2.5kg load is ~7mm. Maybe the springs in your Nobsounds are different.  
Nobsound springs - load range
I don't have the Townshend pods, but I have the podiums under my heavy floorstanding speakers. They use pods on all four sides that are fixed to the podium and that have a knob to adjust the preload on the springs (in a certain range, there are di... 
Nobsound springs - load range
Some thoughts based on my experience meanwhile. I have Nobsound springs under my Streamer/DAC, my heavy mono blocks (44 kg each) and my Powerfilter unit. My initial attempt with the DAC (~12.5 kg) was with 3 units with 3 springs each, as this was ... 
Best 40 to 50k used speakers
+1 for the MBL 101E Mk II.I heard them at last year's Highend fair in Munich. It was so much better than anything else I heard so far. Couldn't resist and bought them meanwhile. You need serious amps to drive them, I have the Electrocompaniet AW60... 
Furutech FI-48 NCF (R) vs. FI-50 NCF (R)
This is exactly what I used for the cable for my streamer/CD Player (modified Oppo 105). The sound is a tremendous improvement against a ~200 EUR commercial cable. I used the Furutech Rhodium spades (FP-209-10 (R)) to terminate the cable ends, the... 
Furutech FI-48 NCF (R) vs. FI-50 NCF (R)
I have tested the DPS4.1 with the FI-50 NCF plugs meanwhile, it sounds great. I have not compared the FI-48, but the dealer said they sound harsh in comparison and he cannot recommend them (maybe that's due to the metal housing). He recommended th... 
Power Cable DIY - Please advise
I want to build a really high-end DIY power cable for my two large monos (Electrocompaniet AW600). I have the Furutech DPS4.1 with Furutech FI-50/52 NCF (R) plugs to feed my mains filter. Wall socket is Furutech FT-SWS N... 
Built a DIY butcher block and iron pipe rack over the weekend
Nice job!!! It really looks great and at the same time is probably highly functional.I built a rack years ago from copper pipes that I soldered together. I filled them with quartz sand to absorb vibrations. Without the sand the pipes were ringing ... 
Big source improvement using CD player
How do you get the Oppo BD 105 to stream Tidal?You can use a Upnp control point that has access to Tidal (I use the Bubbleupnp app for that, select Tidal as library). The Oppo 105 acts as a Upnp renderer, that you can select in Bubbleupnp and stre... 
Sound, neutrality and the pursuit of everything
I think the only true reference is comparing to purely acoustical live performances (classical music, chamber, orchestra, opera, rarely jazz in small rooms). Even for those, sound varies a considerably based on room/concert hall acoustics and list...
