After a provisional cleaning of my crappy Yamaha C2 preamp, I got +/- balanced bass and then made a bit of discovery: Changed the parallel R in the HF circuit of the UK crossover from 50R to 25R (and switched the xcover to the treble boost mode which...

Rick, sure, working volltage is important. What does your inverter require in the way of current in order to produce it's rated voltage at its rated current? I can remember times when I measured "correct" voltage when the battery was functionally use...

I remember when I built Melquiades I detected that quietly of wire that feeds the grid of output stage with bias, quality of soldering or any other minute detail on this wire was very auditable. I also detected that the proximity of this wire t...

Jeremy, another few lead that I think might conceder.
Manly Labs has their 20-bit digital to analogue converter that uses the Pacific Microsonics processor inside. I was told that is available as the “street price” for ~$6K-$7K and it might be a “f...

As the writer of the above-referenced propaganda, I am pleased to once again tweak the whiskers of the cat.
First off, this is promotional material so what the heck do you expect? Every brochure offers a new benchmark in performance or it is not doi...

Finally, I'd appreciate your opinion on the scheduled implementation of regenerated electric power on my system.I am planning to hook up my entire gear on a single PP1050hv (230V) unit:2-channel:

Yes you don't want to go over 0 "dBFS" for sure. In fact it is not good to even hit 0 dB from what I have read in an AES paper. Something odd happens when you play it back (I can't remember the details). I shoot for peaks at -2 or -3 dBFS when...

The whole presentation of sound is very different with your and my file. Your file is very lush sounding. It is very pleasant but a bit too euphoric for THIS music. My file is much more dynamic (if comes from my transformer) and in the way this dynam...

I spent today good 5 hours listening my new playback. For somebody who do not know me it would look idiotic to listen the playback with such a huge amount of problems and do not make any efforts to correct them. Defiantly the problems are huge: the m...

OK, maybe I got too zealous with the notch filter for the Reps. I aimed to bring it down 6 dB at ~2.2k Hz, using .47 mH and 10 uF against 10 Ohms for the notch, with the Reps itself at 7 Ohms. Right now, drums are too backed off, there is no "hair"...

I just wish before I start my project I read a few detail descriptions of the similar projects. Unfortunately they do not exist and I well understand that my project is in away an exemplary for the horn-minded people. All midbass horn are different a...

This gentleman's set-up makes me think very much of the one I have in mind for my new room in due course. Whilst as Romy points out, the room might well be on the small side, it has a very high ceiling (say 4.5 m) that in my mind always presents fabu...

I have come across this company mentioned in a preview on '6moons,' and the information on the company's website suggests that this is in theory really a complete solution, and one that makes sense even to the non-e...

Tuga, clarity is certainly an important prerequisite for true dynamics, where "dynamics" is the musically meaningful idea of differences as applied not only to SPL but also to "rate", such as the space/contrast/interval between a 1/8 note and a 1/16 ...

I assure you that my experience has very little meaning to others as I do not look for “better tube” but look for a tube that would go the best in my specific DSET application and in very custom application of Macondo MF channel. Also, a local gu...

Whatever biggest pressings names they do not throw I always feel defensive as any given record might be whatever it is.
There is however the “pressings” that keep amuse me with consistency of good quality. It might not be always good hi-fi jou...

Well, I experienced the same exact phenomena with using different 2A3 tubes as you remember, which I do believe has to do with the mechanical harmonics in part.[/quote]

I see, what they did – the built a perfect sealed chimney with two fans to suck cold air in and two fans to suck hot air out. Well, it might work, even though I do like this idea. I absolutely do not see why such a hot and large tube as 6C33C sha...

Romy Your file was burned in wave format you provided as-is. It was never processed by the Korg. I conducted my test to evaluate the sound of 176/24 files on my system. These files came from you, Reference Recording and my Korg and all can coexist un...

Connected today Melquiades and Macondo in new room. Macondo uses drivers as they are – no time or axis aliments of any kind yet, no Insertion Channels, no level calibration by channels. I just in-phase the channels and sat to listen, to see what happ...

OK, I decided to stop today to do what I do as it does not feel like me anymore. For a month as I live in here and have the playback up my playback is a source of great pain and I do not like it. I am accustomed that I turn the thing on and USE it. ...

First of all we need all to understand that all channels attenuators need only for setting up phase of playback live. When the installations are set up properly then it is all not necessary. Anyhow, if the upperbass has less output then you might use...

Ok, I desired to go to the bottom of it and found what was/is the problem with Shelter’s tendency for high static. First I checked the arm. Putting 3 different cartridges (with own head-shell) to my 3012I recognize that there was zero static du...
