Murat, this latest information from you has gotten you farther along than you might suppose at this time. From what you now say, it sounds like 6 months would be a minimum amount of time for you to spend getting a sense of the Sound you are after, a...

OK, it makes more sense as you add some details. Meanwhile, I looked online, albeit half-heartedly, but I did not find anything significantly informative on these speakers, even at BD's site. Did I miss something? As you have seen, your proffered pi...

Hi, [quote user="Chirag"]103 or 103R + mass loaded SME headshell + 3012 or a 3009 + Seiki 1500 + hagerman opamp phono stage (good only with select parts and battery power) or an EAR 834 (with some mods) and some old...

Hi Be,the thread is about the "bad" reputation horns have with "audio" people. Applying liquid dynamics gives them more fuel for the fire, that is why I avoid using stuff that really doesn't apply. We have no real flow of air or "turbulence" in a hor...

Dear All,I wish to commence gathering the components and finding the craftsmen necessary for my DIY speaker project, but wished to bring my proposal before this forum in order to establish whether it's intrinsically worthy, and whether any simple imp...

Maybe you didn't mean that it would be necessary or even desirable the existence of some "tailor audio", though I understood it implicitly. It's my fault. Custom audio (and not DIY as it's commonly practiced) is something that might work fo...

Well, John, I had a feeling it was something like this. Plenty to process. It looks like the only "easy" road for the DIY crowd here at this point would be (isolated) filament supplies using your pre-loaded boards. In the meantime, I seriously dou...

I helped Romy shuffle around some hardware and connect some cables yesterday. That damned table weighs about 100.000 pounds. This was one of those once-in-a-lifetime opportunities to see live, in-person how Romy thinks about audio and incorporates th...

Looks like I've found a solution but I don't understand it:
1) Lifting the phono ground from the PP with a cheater plug and connecting the phono case to the SAME PP ground with a separate cable not only does not bri...

Hi,[quote user="morricab"]Thanks for the info about transformers. It is as I expected, however, that these passive devices are not passive sonically at all. I agree with you that the higher quality of the transformers should lessen the effects ...

[quote user="Paul S"]But why would you consider brass connectors because of 95% of boutique RCA if the idea is to wind up with the best signal path?[/quote]Of course not because of that! The ideal would be the connector I've shown but made with pure ...

Adrian, Thanks for a most interesting post. I can't fully respond to this as I don't have the new tube brands you have. I posted earlier regarding my personal findings with the EML 45 solid-plate versus NOS however. Ultimately I found that...

Thanx Romy,
Yes, fitting "time produced" into the matrix is an important piece of the puzzle, don't think I mentioned that one.
Holco resistors are a great example, are in my notes, along with other resistors, and caps, that have changed.&n...

[quote user="Paul S"]Over time I have observed that, in most cases, one quickly turns the corner from "enough' connector mass to suddenly arrive at "too much" connector mass. I started out with a cable clamp like Jessie shows for my 6 gauge "dedicat...

Moreart, somebody sent me this link last year. You are surely the DIY pioneer of back loaded Manger.As you probably know this is a touchy speaker to work with. Rated at 91 dB/W input by the factory, we measure ~91 up to near 92 dB/1W/1m in our two mo...

Haralanov, do not write stupid posts, you have “no experience and no knowledge” about it. Also, do not propose to look at any other speakers as looking is very a deceptive activity. There is a phenomenon of vision that called “phantom visual reality”...

And as one of the other perpetrators...The nature of this kind of thing is compromise. The owner of the bass horn system wanted to run them together, for the enlarged horn mouth, and so we did - there was never going to be enough time to play about ...

I've only had the pleasure of listening to 'professional' horns (whatever 'professional' really stands for)--horn normally used in concerts and small venues. (It was always so obvious to me--by listening--that the range of the horn-loaded 'bass...

hi Romy. Nice topic! I have a very nice memory. I started very young, supported by a friend who tought me a lot and gave me books to study. I learned the basic formulas and started DIY speakers from purely technical perspectives, graphs, math, calcul...

These shops are generally mom-and-pop sized and may carr...
