OK, now the SA8535 driver is fully broken-in and well-habituated. I have no idea how the “Stage Accompany” suggests using this driver from 1000Hz! From what I observe, at MF this driver sounds very “flat” and very none-impressive. I have suspicion th...

[quote user="TonyB"]Romy, what are horn flare frequencies of your horns? I understand that both are Tractrix. My guess is that the midbass is 125Hz with a sealed rear chamber and 4" throat. Correct? [/quote]They tunes for 115Hz and pushed in room dow...

Trying to gather and get my thoughts in order, in order to share them, I just remembered a recent mod that John Wright happened to mention specifically. While I believe John regards - and guards - as proprietary his ideas for reworking this gear, I a...

Dear Romy, regarding your efforts to solve variations in mains power supply, there has been an interesting thread on RAT related to the use of toroids as power transformers that morphed into a discussion about the level of DC offset in mains power su...

[quote user="Romy the Cat"]Did you try to listen and did detect sonic benefits from slaving your PC interface from you DAC? The Cat[/quote]Oh yes, I've tried this for sure. There is a difference between the three modes; DIG_IN, REFWCLK and MASTER. Th...

What might be very interesting also is to learn what DC coupling in power amps would do generally in term of Sound.
The first time I thought about it was a few years back when ...

Ok, I found my RTA cable and did some very basic measurements of what Macondo does in the room. The results were in the direction that I anticipated but worth in amplitude. My right bass channel that that sited right next to the equipment bay has no ...

Hi,[quote user="morricab"]no mention by the manufacturer what brand of autoformers are in use (or if they roll their own). [/quote]
There is one thing I can say. Nickel Lams are bright, shiny and light coloured. Steel lams are dark and dull. I...

[quote user="Paul S"] The "calm HF" effect is something I have long sought but seldom experienced from repro, and I have blamed the amps as much as the ribbons. Mere HF extension is not enough. Hard to say whether the amp or the rib...

Lately the Vitavox electromagnet project looks like moved to a fruitful direction. Well, I do not know if the direction would be a real fertile but it will be going somewhere instead of talking… that is always fruitful. I have quite good support form...

hey romy and all-i recently came across a strange phenomenon (to me.. maybe not to everyone else!).I just started using RTA as a method of evaluating my results with my own 2 way speaker system, and I'm finding that I'm ending up liking the sound of ...

Well, another page of my saga with APS regenerator is turned. I got the updated APS unit. It kind of “works” as I redefined the definition of word “works”. Under normal circumstances I would walk away from it but there are some moments in my “bad ele...

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...

Mumford,
Let clear first with terminology. You post said about “Incorporating active crossovers into DSET” and I think it is not what you are interested; at least it is not what I am practicing. An active crossover implies a use a dedicated active s...

Wojtek, I am indeed hemmed in by the fricking electricity these days, to the extent that it is about impossible to hold on to a baseline for reference. And the Lowthers only make the problem more apparent.Yes, I still wonder about how I wo...

The first order from iran (2013) was 4 unit (4 pure power 3000) and Richard delivered 2 units after 4 years .
after over 1000 email/phone call Richard not delivered those 2 units yet.
I do not know what is going on but I hope ...

My comments are rather discouraging arn't they! Not my intention but hopefully helpful in the long run. Regarding time alignment i just wanted to raise the point i think it might be more relevant than initially anticipated by someone considering buil...

Well, I would advise you do not order any horns with aiming 2490.
Get the drivers first and order the horns AFTER you feel that the driver
satisfy you. The fact that the loaded driver can hit 300Hz does not mean a lot.
You need to like the sound o...

[quote user="Romy the Cat"] Even if it is possible with a given (multichannel, faulty design) loudspeaker then the DPLOS become very fragile and appears/appears too sudden, without a gradual improvement while approaching the DPLOS. The keys are phase...

It's not just about order. You don't do it because you or others are obsessed with the advanced aspects of audio..perhaps so much, that we forget about the basics and the possibility of categorization that's simpler. Nothing will be perfect, I sure a...

Enduring a quite aggressive schedule to the end of the month to finish the horns, I realize how much work is still ahead. As now both of the horns are built. They are no prepared to be painted yet and second skin is not built. This notion that ¾ laye...

My experiences would confirm that much of what gives depth to “silence”, does indeed lie in low the frequencies.
In order to keep peace with my neighbor (even at very low listening levels), after 10:00 PM, I absolutely must attenuate the ultra-low...

Perrew,
I do not know if you use sarcasm in there but Lamm LP2 is not my bellowed phonostage. In fact I am one of the very few people whop do not like it at all. How much in what I do not like in Lamm LP2’s MM section come from the WE417 tubes...

[quote user="N-set"] The only purely theoretical point which is intriguing for mein the whole multiple drive idea is whether one can achieve a uniform "floating" rotation: the forces perpendicular to the spindle balance out and the spindle rotates wi...

Of course the idea of "minimal" needs context and a priori determinants, like any idea at all, and I don't see that the Regas belong in this particular discussion, at least at this particular point. OTOH, the Continuum is another good illustration o...

It is amassing how idiotically-predicable the recording industry is. Industry is not a subject but Industry is compilation of individual peoples - presumably idiot - as by their efforts we have what we have. I would not criticize the quality of recor...

Wow, the Definitive Audio is half hours away from London, this is good news. I did look at Google and it said 2.45 Hours but I might look some at something different. We probable will be staging near Royal Abler Hall, which is center city. We are ver...

A few years ago I did not “get” Bruckner. Then, like with everything else, it changed. And of course being a compulsive feline, I can not get enough of what I like….
I admit that I listen quite a lot of Bruckner lately. There is something very medit...
