Romy,do not spit in my eyes as I do have solid state PassLabs 350.5 but even with this 50W Class A amp (push pull) it is exactly the same problem if it is switched off completely even for a short while. I can take ~ 2 - 3 days to be back to norma...

Yes, Romy, it is certainly an info-mercial first, with all the usual flash/buzz "facts" in play. Also, although all "studios" I know of are "balanced", many of the "hot-rod" studio guys also use all sorts of "power conditioneers". For one thing, it...

Yes Paul,DSEP is planned. Actually I have already experimented with it only with the 12" Fane neodymium midwoofer that covers 80-1K and using 1 cap for the low pass filter. I really like what it does. I am comparing how it works with ceramic and neod...

Spent today a whole day moving the boxes, do some measurements,
fighting with REW interface, thinking, some listening… Found some bugs in the
system that I think screwed my initial feeling. The bugs were mostly by Thomas

[quote user="Paul
S"]If you said anything about your 15" VitaVox in the video, I
must have missed it. What frequency range are you running them, and what
is low-pass filter? Given your prejudices, I suppose the cabinets are sealed,
so they can't...

I am still waiting for a (single stage) tube that can make full range Music via speakers. I mean, this is the real issue, isn't it? Sure a good tube will pass a "full range signal" through the right transformer; but where is the tube that will do t...

Congratulations on the build! anthony wrote: Yours uses all toroids, or mostly so, which are more efficient than the EI that I use.
Why have you chosen EI vs toroids? The latter emit less.
Cheers,

Actually it turned out that LE5-2/2105 are much more complicated driver and to sound right it need way more complex crossover then juts a band-pass the I initially unused. I spend some time with it today but did not find a configuration the I feel co...

[quote user="Romy the Cat"]Funny I thought that that for MiniMe it would not be so critical but as soon I plugged the DEQ-2496 in MiniMe pass I have heard that depersonalized DEQ sound.[/quote]It is funny how some people seem to not hear this at all ...

Mani, I have long run an 8" Lowther DX4 down to 150 hz, over 2nd order high-pass. My impression after plenty of listening is that I wish I could cross it at ~ 400 Hz. The "problem"is not simply how "low" the 8" driver will go but it is also a quest...

It seems like I should just abandon the idea of using the Druids... and trying to get some sort of coherent integration with my WB-Chimeras (acting as the lower- and upper-bass units)... and running the whole hodgepodge with totally different amplifi...

I think low power ss design is the only way we can make ss to sound good. in my idea all high power ss design i heard had no emotion in their sound in comparison by good SET designs like AN UK Ankoru.the first SS design that make me happy in comparis...

Zanon, I do not mean DEQ, but that is one way to do it. D[SET] is another way; and it can be done in real time, by a couple of means.If you actually settle on the mid-field monitor approach, you will want that sort of speakers installed before you g...

I do not use in Injection Channel any fancy cables. There is not a lot of need for it. The Injection Channel is mixed with M...

Hi,I've just taken receipt of a Model 2 to use as a DAC in my study (using the ADC occasionally for recording live from a mic). I would like to feed the balanced XLR outputs of the Model 2 into the single-ended RCA inputs of my Berning Siegfried amp,...

Yes, the layout kind of not optimum. You might try to lay the transformers sidewise and to make the RCA atop, above the transformers. Still, I hope you understand that your hum has very little to do with layout. Properly grounded unit shell has no no...

Paul, so far the interconnect shields were connected to the phono pre grounding bolt only--I do not want to pass any equalizing currents between the TT and the phono via the shields (the TT chassis, armtube, etc was connected to the same place via a ...

Yes, a cheap inductive l-pad between OPT and S2 in midrange channel. Interestingly, the frequency response of the first order Lazy Ribbon is remarkably similar to a response you posted somewhere on this site of the Water Drop with third order filter...

Again, about the stupidity of non-critical perception.
I have seen in audio all over – people visit each other, listen each other playbacks, in response to the hospitality of the owners they pass numerous compliments about the sound of given i...

[quote user="Horn Savant"] I think it's about the same as free-air resonance - backwave to entire basement. Precedent: pre-war theatre horns(open rear like Shearer/ERPI)(unlike post-war reflex tuned designs like Altec A4)(I don't like reflex boxes - ...

Romy,Interesting video. The first thing that came to my mind when you were talking about HF colours and the "clean" RAAL Waterdrop tweeter, is perhaps adding colour to the RAAL. Instead of blanding out the midrange S2 and injecting HF colour with t...

[quote user="DERRICK"] Although I think that Romy has voiced some fair criticisms (bearing in mind that he has not heard these speakers, I am sure that he would moderate his opinions if he were to hear them. [/quote]

Somehow I massacered the formatting of the last reply. The past days I was listening to the speakers in every imaginable configuration. Sometimes I based my changes on "accepted theory" of crossovers and math, other times I just made...

As I am slowly put Macondo back to the business a question come to my heard: how can I make the Injection Channel sexier visibly? As now Macondo is re-assembled and reinstalled but with no Injection Channel sitting atop. I extend no room for argument...

[quote user="Joe Roberts"]At Munich, we cranked the Aporias up with a 20w 845 SE and they did not catch on fire but our goal for the speaker is "big horn sound in normal sized rooms"--and 8W will do that.[/quote]The Manger catches on fire with some m...

II would like to pass a word of warning about the C-15W driver. I do not know this driver but it looks like it has dual voice coil. This might be a hell or blessing. On a paper the idea sound very interesting but unfortunately when I seen it it never...

in this experience. I agree that FM broadcasts from live performances or live taped performances have the features that make music like nothing else in audio. It's the source I enjoy most and that is more educative for me. I would be happy participat...

[quote user="Romy the Cat"]. What was your resonant frequency after loading? The 416 are 25Hz drivers, after loading and with two drivers it might be deep in teens. From the picture it looks like you keep the back chamber of extra large space, or eve...
