It was not so long ago that the Super Milq was a twinkle in Romy's eye,and now it has come to the point he is a strong proponent of DSET (not to be confused with DH-SET). I am always a big believer in the power of topology. I was thinking about...

Getting OT, but: Another important sub-set is that many or even most who put together a system do not have any sort of well-developed personal references. Many simply hope to get "better sound" from their next purchase, and in these cases purchasing...

I'm not sure if the Salamander-style rack (wooden shelves supported by nuts and washers on threaded rods) will support 800 pounds, but if you put heavier items near the bottom then a wide heavy-duty version might be fine. Besides Salamander, some ot...

Obviously I have not carefully read everything you've written about Melquiades, mostly because I have just been stopped in my tracks by the ML2s, so I still have a lot to think about as it is. But if anything could "sell" Melquiades I'd guess i...

Thanks Rowuk,I have used resistor switches before. In this case it's for a studio mixer so I want potentiometers. I'll look at the Alps stuff, thanks. I realise that question might not be received as "advanced audio practice" but it fulfils my object...

I have a 10KVA Isolation transformer that feeds on two separate 8 ga cables running direct from the house meters into an breaker into de transformer. This breaker is the one I use to turn my system on and off. The Isolation transformer recieves two ...

As I have shared several times here, I happen to regard the Lowther as nothing more than a means to an end. Partly because of this, I have taken my lumps with this marque. Today, I am pleased to have finally made the speakers I imagined 6 years ago...

Well, thanks for the heads up, I was planning on giving myself a PP2000 for Xmas, now I have to re think this.I used to have a 10Kva Isolation transformer and a DIY sort of Line conditioning system with a bunch of nice 4.7 mfd caps between Positive ...

"I would not trust any seller who clamed that they tested them." -- R.B.How annoying that your words were prophetic, Romy. The 6N6P tubes just arrived from St. Petersberg in a plastic mailing bag rather than a box, and one tube...

Romy's recent post on the trials of 12-channel DSET hi-fi made me feel a little better, but his point about maintaining performance is well taken, none the less. One simply must have an aural reference and some rigorous methods for keeping things son...

I think I would relate my own DIY experience more with Colonel Aureliano Buendia making his golden fish.
I have been tempted to ask you about listening methodology before this, but decided not to, think there probably isn't a formula. Paying atte...

Thank you Romy,
<<The multiamping with Super Melquiades was made with intend to optimize the output transformers and to eliminate the interference between the inductance of the upper bass driver’s coil and the MF driver. I still use the speake...

Again, not to make a "formula", but I was thinking about the possible roles of the speaker in "offsetting" the typical upward-tending tone/harmonics of hi-fi. Sure, there are lots of strategies to "deal with" the upward tendency. These ideas mi...

hi mikei heard the avalons at the factory of a manufacturer of wonderful tube amplifiers in italy, http://www.angstromresearch.com/pre_ita.html ( certainly these guys would make big success in the states, if they were able to produce more than 5...

How great it would be if there was some kind of "breakthrough" every so often, in order to make linear "progress" with the driver evaluations and speaker development! In fact, it is almost impossible to keep meaningful "controls" in place between eva...

I did not know that there are any modern V-FET designs. As I understand, the V-FET transistors were available in 1970-1980 and were not produced since there. From what I heard that the DIY people who try to do V-FET amps buy old Sony and Yamaha machi...

LaurentAlthough I have whined that the ML2 requires "tweaking" to get its best, the truth is that it is closer to the dream of acceptable "plug and play" performance than any amp I have ever used. Which is a long preamble to saying I am hardly an ex...

Yes, the laconic clarity is too rare and too worthy to let go. My limited experience suggests that the 45 may have this very special ability, taken alone. Conversely, the "good" 6SN7 is wonderful with respect to tonal...

I would like to share my observations about public perception of Melquiades - The Realty Reconstructions Amplifier.
Melquiades, or as I affectedly-abridgedly call it “the Melq” was released to pubic exactly a year ago:

Silbatone made a Demo with those Horns (the big ones)They said, it is one of three existing WE Horns, made 1935/36 (only mod is the addition of the tweeter you can see there). One Horn is made for 3500 Visitors, so we got a 7000 People Demo with them...

Hi Romy, I ended up using a TAD 1101h 11 inch driver, 97db, 38fs, and is what I believe a stronger cone than the Goto 8 inch. The DIY mid bass horn is a 1/2 space 53hz hyperbolic horn with 5in x 5in square throat. Length is about 8'6", height of mout...

Yes, it looks not particularly sexy but it I was made to fit and it is for sure very functional. You shall not worry about attractiveness as when I pile up on this thing TT and whatever else will be located on it then it will have completely differen...

How do I hate DIY? Let me count the ways...Is there some reason you cannot make through-holes to facilitate soldering leads to your copper sheet? Use a hot iron (800 F) and plenty of aggressive flux to pre-tin the holes... Stand parts on short leads...
