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="Lx_"] The second sentence is my own conclusion. It was not my intention to imply that it is yours, sorry for the misunderstanding this may have caused. We both agree that PP can be sensitive to incoming AC. The context and circumstan...

I was keep listening my Dutch-made SA8535 tweeter. There is a lot of deferent with this tweeter and I think it is a good time to pass my early observations about the tweeter Sound.
This driver is not a ribbon tweeter as the Stage Acompany frau...

I just posted yeastoday the post above and have got already a few emails asking about the “new” ways that I am planning to use S2. OK, let me to explain what is going on.

[quote user="Paul S"] Speakers: I built a version of Dick Olsher's 3-way Diamond Edition BassZilla (hard to find at www.blackdahlia.com), and I tricked it out considerably from his mule. Bass is BR, 15" Audax P380MR, which is a nice semi-...

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 Rohde & Schwarz EU-6201 tuner was made for German Ultrakurzwellen (ultra short waves or FM) Broadcast Network. The idea was to have a chain of wide-bandwidth composite signal receivers that feed re-transmitters. I made an attempt to accommoda...

OK, it took for a while but at this point I have nailed down all design aspects of the new 6-channels Super Milq, and particularly its input stage. I have listen and evaluated all solutions that will be implemented in there; selected, appraised and o...

OK, thanks. I would leave for others to decide what the “higher resolution image” might mean. It might be some kind of untranslatable Japanese folklore. The more vibrant color palette is definably a valid accomplishment, no one knows through if it is...

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...

[quote user="jessie.dazzle"] Assuming you go ahead with the mid-bass horn project: If you decide to run the woofer towers along with the mid-bass horns, it is logical to assume they'll produce much of the range produced by these new horns. [/quot...

[quote user="jessie.dazzle"] Romy's comments on "axial rotation" of the horns (meaning in this case, angling the horns) has me thinking. I had planned to build in a vertical tilt adjustment for horns located near the floor and ceiling... I woul...

[quote user="skushino"] Edgarhorns weren't an obvious choice. Many horns never worked for me. The Avantgardes left me cold. So did the single-driver crowd (I just don't get it....), Altec VOTs, PA systems, etc. But there were some systems th...

[quote user="haralanov"] Yes, you are right. Power – you have almost unlimited power. Dynamics – you have as much dynamics as you want. But there are a lot of associated problems with that kind of dynamics. The following illustration is taken by ...

Here is the list of the thing to do with Vitavox S2 in order to use it in 4-ways installations. The S2 must not be used in 2, 3 ways systems. It possible to do with S2 whatever you wish but pretty much any other way to utilize them produces some very...

Ok, I made some further experiments driving this time my S2 driver from Milq DH DSET. The hell of the sensitively - it was too much. So, I went for 4:1 inner-stage ratio. The result was very successful and the amp looks like was able to get more...

There is no "one tube DHT amp." There are only amps with gain in one box or two boxes.
Your 6E5P tube is not so special. People have been making WE437 spud amps since the 1960s. There is a class of amps that use a high-gm tube driver and a DHT out...

Chris, I certainly did not mean “costs nothing" in the literal sense. I meant that it costs as much as any other driver to make that Feastrex. Come on! If it is an electromagnetic driver then how much does it cost to make a few pounds of core (even i...
