My first thought on looking at your photo: "Night On Bald Mountain"! This particular set-up might work especially well for Halloween Hi-jinks!You might even install a remote-actuated "turntable" with different filters... Best regards,Paul S...

I had not good result with line filters. is there any experience with Ayre L-5xe Line Filter?https://www.ayre.com/literature/Ayre_L-5xe_Literature.pdf...

[quote user="serenechaos"] on 3) & 4): Dave Slagle, Intact Audio, knows a LOT more about transformers than I do, and the nickle autoformers I got from him work so well, I totally trust his (and/or Jeffrey Jackson's) judgment to over my "guess...

There seems to be a lack of useful feedback on the actual sound quality of these oddball, relatively rare TAD mids. So I think it would be helpful to share some basic observations I gather after listening to them for a couple of days. I install these...

[quote user="Romy the Cat"]Another a very valid thing to try is to see of the same difference with the same recordings happens with different DACs, preamps the you will take care of the absolute phase. [/quote]To date, my listening has been with my f...

[quote user="twogoodears"]I'm pretty interested in yr. opinion about the possible choice of best, safest, smoothest way to use solid-state amp/low-end with "Triamp"... ok... 3-channells DSETs... and my system upper ways... what slope do you think...

Romy, Big thanks for your answers. But i've got another question :)You mentioned gas regulator as grid current "absorber".Very good point, because personally i hate to use resistor as a grid leak.Instead of it i'll use choke - almost with any tube, i...

Romy,Just realised that I had dual highpass filters on the TH, which more or less cut off frequencies below 50Hz entirely. A lot better now, still much to be made of course./Marcus...

Well a scepter or a baton... Last night before setting up the RTA, I listened to a recording of orchestral works from Strauss (Kempe conducting)... It was early enough that I could "air out the system" a bit. And Ok, maybe I don't have all ...

The post sounds like the 500 word synonym for "analytical". In my experience most changes from a satisfactory prior model means it gets more analytical rather than more like live music. Your description is very close to what I would have written abou...

Perrew,
LCR is not active at all; it is the very same passive EQ as your RC? I think you a bit confused with terminology. The main logical explanation (there are many of them) is that capacitive filtration is very bad one and need to be minimi...

[quote user="slowmotion"]Good news if the analogue stages of the DCX2496 is so bad. So the improvement of a modified unit should be worth the ekstra work, and remove some of the x-overs negative influence on the sound. Which is always good to know be...

Audio Federation have publish some images from the Silbatone room at CES, even it is in their new idiotic format of the “magazine” but they still visible.

What attracted me in the images is to see wh...

[quote user="Canuck"]Romy Have you ever tried a PUREPOWER device feeding something like the Torus RM20 which has a huge transformer and then out to the components? The Torus stores a lot of energy in those huge transformers. Do you feel this ...

[quote user="Romy the Cat"]
The biggest mystery for me and it is what I am thinking
about all time is what digital filter does to my sound that analog could not.
Is it a precision of the Bessel curve? I hope it is not. I hope it is something

I do suggest to re-read my post above where I stated that Pacific has remarkably similar sound to Bidat. In Bidat there is one quality that sets it apart from any other converters out there – the Bidat’s dynamic bursts are orders of magnitude less an...

[quote user="RonyWeissman"]Hi romy, thanks for info. I am going to stick with the 2-stage plan then as it will not be DSET but full range and my mid-bass is somewhat barbaric at this point. I have found someone to build for me, though we ha...

[quote user="drdna"] So what are the effects of good electricity of the PP2000? It may be a good idea to look at the frequency response and harmonic distortion of the system to see if filters in the Macondo speaker system may need to be adjusted now ...

Yes, and lucid explanation why parallel caps on AC between neutral and hot affect sound does not exist. To make the things worst I can tell you that you can put 4324 regenerator or transformer of any kind after this cap you still will have no bass. I...

I found 2 recent room upgrades made life more comfortable:1. We recently installed a "cork" floor. Acoustically it is quite pleasing, as it is finished with some semi-gloss sealant but also quite sound absorbent naturally (irregular texture/soft surf...

[quote user="Romy the Cat"]Hm you are true in the “terra incognita” territory as far as I concern. The preamps are mystery to me. All my attempts to make any decently sounding preamp or even buffer failed. To me Placette was truly God sent and if I g...

So, the first DSET is still downstairs on the electronics bench and I am back to work for a while, but not too hard and not for too long (I hope). I've added all the filters and checked and tested and changed some more things and decided that it was...

Ok, it turned out that I had all caps and coils "in stock" necessary to adjust the filters very close to Romy's recommendations.Its still not perfect, and I had the mic 1m from the membrane of the driver (had not yet rea...

[quote user="Teflon"]If I understand you, your amplifier uses line level frequency selection at the input to each channel, and the output of each channel is optimized for the frequency range of interest -you worry not about the performance of a chann...

Understanding Line Array SystemsBy John Murray
Behind the buzz, there are a lot of factors at work in line arrays. An explanation and comparison of current models. This discussion can’t be contained in just a few paragraphs, so we must start with th...

Interesting, thanks Guy for posting.
Let analyze what was done in there. It looks like well-thought, time-aligned, looks like multi-amped configuration. BTW, how the filters were implemented and what (slope/order) filters were?
To my knowle...

Macman, the “annoying peaks above the usable frequency range” is something that your specific installation might have in context of your room and your acoustic system location but it might not be a characteristic ...

BTW, I was kind of saying it many times in past but I think
it high possible that it was no lost in translation. Anthony, if you are trying
to implement with your version of Milq the same multi-amping with line level
filters at input then make sur...

[quote user="anthony"]Romy, I
appreciate that this is an old thread now and that you may not remember
everything from your time developing these amplifiers, but I have a (hopefully)
simple question about the upperbass crossover in the schematic ab...
