So, I have finally started testing a single Bass Cannon in my room.First, I had to get the rigidity as high as possible and then damp the steel ringing as much as feasible. I used butyl rubber/aluminium automotive deadener on the inside of the tube ...

Me being exuberant about the new ULF capacity does not necessarily mean that ULF contribution is right and proper, let me to explain. There is a musical event that has it sonic representation. This sonic representation better or worst was captured by...

[quote user="drdna"] I can tell you already it will work. I have experimented extensively with adding lengths of metal to cables. It works well, but you can do a lot more by fine-tuning the amount of metal and in fact adjusting it slightly from l...

[quote user="cv"] I bet Yamamura is using non-causal filtering... this is all running off a music server, so could process everything offline. [/quote] Chris, there is no such a thing as “non-causal filtering”. Filtering is filtering, would it d...

[quote user="peter foster"]The station that I most listen to is 105.9 MHz that broadcasts from one location 50 miles away at 100kW power and that is detected by 2 FM aerials mounted as a parallel array with rotator and ~ 40 feet of coaxial cable to t...

Paul, what I mean by 'Drain GND' is your idea of a GND cable connected at one end only. I have no access to mother earth and cannot install a dedicated rod. To avoid confusion, below is my actual power line and GND scheme.
As for...

these are my findings about computer audio after some trial error:1. computer audio is very very hardware/OS/software dependent. computer structure is multi task (time sharing) and using it as a real time single task processor is not easy.even small ...

[quote user="darkmoebius"]I asked Jim Hagerman how long it takes to break in interconnects, power cords, speaker, cables, and preamps? He replied - "Usually about 40-50 hours on a FryK. The amps are fastest and get most of the way overnig...

CEC TL0 3.0 (I have CEC TL0 3.0 model 2018) is my favorite Transport and the question is could it be improved?
CEC has very very good dynamics good bass good pace good rhythm good dimension very accurate sound, low jitter and very tr...

Ah, you use those gorgeous VPI boxes to host transformers. No wonder it does not sound well, what did you see the anything from VPI sound well? Seriously, I do have those VPI boxes, I do not remember where they come from to me but they are too go...

[quote user="PurePower"]p.s. Do not follow the advice of creating a new ground for the audio system alone. Multiple grounds can cause very dangerous, even lethal, unintended consequences.[/quote]
Actually it is incorrect. I do understand why a...

[quote user="Romy the Cat"]I did not say how my saga with APS Pure Power regenerator finish but it never finished. Since the end of the last year the regenerators is sitting in my closet and I have sent the unit’s main board to APS people for the “re...

[quote user="steverino"]Well I meant that in cases where the AC power wasn't simply larded with grunge but was irregular with outages you didn't need to be an audiophile to appreciate the product. Of course audiophiles find all kinds of things essent...

OK, here are some follow up thoughts after the completion of the project. I am sure I will burn it for a month or so. I think everything will be fine, I do not expect any issuers technical or sonic. The way how the entrance to the corrector done it i...

Yes,
miso, I had exactly the very same experience. I did not experimented with high
voltage wires and my high voltage were a few premade power cords that I got
from different manufactures. Interesting that shielded cable BEFORE PP3000 aloe

Yes, the last cap of power supply much be on the side of load as it shell have a short path to ground. Without it you will have “less bass”, more crosstalk in case it is a stereo amp with single PS and a few other negative things.
With cables is mor...

Thanks, Paul.
I never saw this company. I did call today to the guy who run it and had longer conversation with him then I intended. Size and shape wise it was exactly what I was looking for. Unfortunately he does not do matching transformer b...

In this section I will brief cover operational parameters of Purepower 2000 regenerator. I do not have a lot of fun to write this section but I feel that for sake of objectivity it is necessary. Also the next section – the sonic observations - might ...

This weekend a friend of mine visited me to listen my playback and there was a very illustrative occurrence. We listening my audio and everything was like it should be in the program. He was visiting my last time in 2002-2003, before the Macondo was ...

I do not think so. There is no such a sing as optimal generic DSET but there is a concept of optimal DSET for a given situation. So what I think would be nice if some kind of company come up with a Reconfigurable DSET . The Reconfigurable DSET, or RD...

[quote user="Romy the Cat"]OK, everything was fine and I might do into the sonic nuances of the PurePower unit. The PurePower drives a lot of switching nose from output. It has the filters but they help only partially. Adding capacitance to the PureP...

Paul S,I usually do not compare source components (or amplifiers or cables or etc.) in this fashion, DAC vs DAC, CDT vs CDT etc. unless I feel two (or more) of then (may) be too similar, like Lampizator and AN UK DACs I like. I prefer to focus integr...

Yes, Peter,
I know that in the Steinberg WaveLab use only Bob Katz’ metering system, still I thought that if they are cooperate then Katz’ Ambience Recovery might be available as a standalone plug-in. It is kind of suspiring that Mr. Katz was able t...

Ok, the one channel of the Milq is up and running. The first assembly went fine, no bugs or problems – it worked fine juts after the build. All voltages, delays and heating are normal; this I would need to inspect everything again after it will work ...
