Chris, I do not do “service” to anybody. I said what I said and what I feel
I do not use phenolics in MF and as I understand nether Steve Schell. In fact I do not think that it would be a good choose for MF driver. The carbon fiber from my poi...

first post... but I recognize quite a few friends here.. so, my straight horns... I like them very much.. I built mine similar in style to what Greg B linked, but obviously much smaller.. mine are just under eight feet long (length of a sheet&nb...

Well, I decided it was time to start using some "proper" interconnects between the preamp and DSET's, ordered them and had them delivered. To date I had been using cheap interconnects from the local electronic shop (literally $6) which should be ok...

[quote user="Paul Costa"]I have a PDF file of the manual if it interests you to read it, I can email it to you. The unit weighs 80lbs, uses 6 6sn7's. What I found a little odd was the spec for the phono is it says : MM Phono Stage Gain: 64 dB at 1 kH...

From a technological perspective, these look very interesting. Unfortunately the nearest place i could audition these is Montreal, but it looks to be worth it. Have you heard these, Romy, or are you also impressed with the price/technology ratio?

[quote user="Romy the Cat"]Hm, interesting. The problem might be in ADC, I/O cared, Recorder or DAC. When you do the experiment do you record the file? If so then you might plug ADC directly into DAC. Might your problem be with cloaking? I do know wh...

Thank you Romy and congratulations on your website, it just keeps getting better and better all the time.
The RCA1428 is a great sounding driver on RCA multi-cell horns. Not that I like multi-cell sound. I have never heard an original 1428 on a tra...

I used to have a few musician friends and played a little myself, but they were never really interested in audio, they did have a system but no intention to sit in the sweetspot or anything of the sort, we used to go to concerts and they would carry...

Too hot to expect the best sound today, and besides I have gotten my morbid curiousity worked up about the recording/playback curves, so I fished out a few LPs mostly to hear/see how they sound with respect to the "shape" of their sound, aspects of w...

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 “Enjoy His Music” published the old celebrated by many DIYers Herb Reichert’s article about his 300B amp ideas.

Jarek,
Thank you for your input. This is nice to have a somehow a list of good connectors.
Today I found Wireworld Pro Audio[1] sell "Silver-clad OFC" connectors (they call plugs). I n...

[quote user="drdna"] Exactly. Thus, it suggests a ground loop internal to the PP2000, doesn't it? [/quote]
In my view it is highly unlikely as a definition of loop itself implies two contacts to ground and PP2000 has on...

[quote user="cv"]Funny, I was just thinking about battery powering of amps... I know you have identified that the problem is more with the sources, but it would be interesting and quite feasible with the Melquiades and other components... wouldn...

Interning that Heifetz has that same “ice maiden” status, primary because he did not express any facial or body emotionalism while he was plying. Ms. Mullova is the same she appears almost like “detached” and just “renders the notes”. It is hard to m...

OK, the new Macondo frame is over as well. Eventually after 6 years of learning how to make the damn horn speaker to sound good, after numerous incremental successes and failures, stupidity and brightness, moves to wrong direction and mistaken assess...

I do not know the characteristics of the Cogent bass driver. I do not like the entire idea of a bass driver be electromagnetic as bass defeat itself first with field coils, still if electromagnets is something that Cogent intend to do then they are w...

Haralanov,
I spoke with a guy who consulted me during my Electo-Vitavox project. He helped me with selection of core material, deliberated the core and calculated the right coil to keep the core mass optimally magnetized. He has over 40 experi...

Hi Romy and thanks a lot for the always interesting topics and discussions going on... I'm quite new to DPoLS and consider the approach of "obtaining sound in a room" more than "speakers positioning" - too often to WAF fullfillment and aesthetics, th...

Hi Romy,I miss-understood. I did not realize you were able to play my file in "natural 96K". Since I am not able to play your file in "natural 88.2" I needed to make another recording before I can really compare yours to mine since my CD player ups...
