Romy,
Why preface my comments ? I've had the same system for 10 years basically. I do use digital crossovers but the 'Class D' NuForce amps are not digital at all. And the NuForce amps don't sound like stereotypical Class D amps, they are very quie...

My room, is 16 to 17 feet wide, 27 to 28 feet long by 12 to 14 feet high with all walls splayed, with a combination of absorption and diffusion on the walls. All electronics are fed electricity by three pure power units originally recommended by Rom...

That was the 4 way system designed by John Sheerin using GOTO drivers on my request. The tweeter is GOTO 160 with S3000 horn xover at 5kHz. The high mid is GOTO SG370DX with S600 horn xover at 1kHz-5kHz. The low mid is GOTO 505TT with S150 hor...

You bring up many very valid points, but still I will continue to use my digital crossover as a very useful tool. But I am also experimentin...

one would take full advantage of what can be done in the digital domain so that the horn mouths could be arranged, not for time but to clean up their other interactions. This would be digital the entire way, solid state music files, digital amplifica...

Hi Romy,So, six channels are now operational in the first DSET. By up I mean the anode voltages on all tubes is about right and the currents are in the ballpark of where they need to be. I am yet to check the DC Offset so hopefully that goes ok.Ini...

Last week found that the distortion I was having was due to some small separations of the woofer cone from the surround suspension probably from age and playing too loud. Applied the glue to them received from English tannoy dealer and distortion...

I'm following with interest the thread and must say that I'm baffled: Goto's "instructions" are - SIMPLY said - a mix between non-existent and wrong... I love what Goto's did in my system... BUT I think I did more with "my own" care, "my own" taste, ...

[quote user="cv"] I gather the Acapella plasma tweeters have a catalyst so you don't get the nasty oxides/ozone etc. Got some old ionofanes on the way so will know soon how well they freshen up the room... They are self-amplified so efficiency ...

TwoGoodEars posted at his blog a report about is listening session or some kind of installation. I still have no idea who’s installation it is: Jean Hiraga or Be Yamamura. Nevertheless, I think it very much worth to look into it.

[quote user="jessie.dazzle"]….. sit back and conclude that, yes, damn it, a pair of good straight Mid-Bass horns is exactly what you need. My reasons are of course somewhat selfish... as I won't like being alone in needing a non-digital delay solutio...

Jessie, in the configurations of the horns and derivers that you are building your mid channels do not exposed too much to stresses. It is not that you have a situation when 1/4 octave more and less will send your channels into suffocation - your hor...

Jorge,
You're right about using identical amps. No doubt.
I have not used Dr. Edgar's passive network but I have tried conventional passive networks on Edgarhorns. They worked alright.
And I have...

fair enough- you're absolutely right, i didn't!it's difficult to get that perspective on sonics without legitimate guideposts-- even with a lifetime of playing and recording music, it's difficult to know what the parameters of recorded sound ar...

For a casual observer it might appear that I am constantly fought with my ULF, finding and loosing better and worse configurations. It might be so but I have a very strong sense of objective of what I would like to accomplish. I want to reinstat...

Bud, perhaps it does makes sense to try the “dotizm” one again. I quite severely review my view on the way in wish I use tweeter. I still am trying to make T350 to work, let see what I end up with. Nowadays my T350 sitting in 3rd order crossover, it ...
