Thanks, Jim, and thanks to everyone who replied in direct emails. Summarizing what was advised to me it looks like as now the input impedance of the amp is around 4.5K. That was roughly what I would like to have, though I would like to go even furthe...

Here is a stupid need of DIY audio level. As many of you know am big lover of Nichicon electrolytic capacitors, even their lowers grade sounds right to me and never made to think about anything better. Still the Nichicon never stopped to surprise me....

[quote user="Romy the Cat"]If you read the very important post: http://www.GoodSoundClub.com/TreeItem.aspx?PostID=5255 then might understand that it lead to a painful research on the subject. I have ton of data now and many experiments done. If ...

Got today a shipment from Tokyo with the OS-106 record. It is the same Ormandy’s Bach with Philadelphia but pressed but Japan. It sounds even better. To hear it today is even more fun than ever. We have very windy but very warm day today and the New ...

I need to tell you that I did not finalize mu Milq DH DSET up to the point where I would listen it. Perhaps I am wrong but the amp even in the last version has some lack of agreeability. It is good on paper, it might even sound right when it will be ...
|
|
Sure, Chris, if I would be able to make the air-trans of acceptable size then I would defiantly go for it. If I pretend that the Super Milq pushed some boundaries (and I do feel it) then to use an air-core transformer for HF channel is exactly what i...

Ok, this is probably the most important section as besides all positive changes that PP2000 does to sound it does this one, the one that I call “softness”, and the values of this “softness” have to properly understood and interpreted.
The “softness”...

It is truly exciting time in my Macondo/ Melquiades biography. The 6-chennal Super Melquiades is done and fully operational. The 6-chennals of left Macondo speaker have build to the 6-chennal Milq. It “works” fine, not it is time to make it to sound ...

I turned the thing on lately. Although the channels do not sound right at this point but there are some moments that I do live very much. I like the mechanical noise that this version of Milq radiates.
The former version had still chassis on PS side...

OK, first off all I have moved the latest posts to the “How to drive 6C33C” thread.
Regarding the operation point. My initial intention was to give Melquiades’ output as ML2 did: 175V, .310mA. What is important is to understand that for LF channel I...

It is kind of pleasant and insulting at the same time. Insulting because I thought I know the Super Melquiades better then anyone else or at least was able to say about the Super Milq Sound whatever might be said. :-)
However, today my ego was sever...

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...

+++ Going back in time to your Super Macondo with the midbass horn, I'm wondering how did the big horn influence your perception of Macondo sound if you remember?
Yes, it is very very good question and essentially the question which r...

Interesting, Very interesting.
I might make some observations now, claming this recent modification as a success. The minor gain of sensitively certainly did not heart but the major advantage was defiantly the “activation of ceiling”. It is hard to ...

[quote user="Romy the Cat"]3) There is a mistake in Milq circuit. The B+ of the driver stage has almost insufficient amount of critical inductance. It was because I drew the circuit having the Super Milq in my head where the PS was feeding 3 stages a...

Anthony, I do not know what you new buffer is. A few notes. The difference between sub 10R and 300R of output impedance is significant for the load you have (Milq) between your new buffer and your 10Y preamp. The type of the description you provided,...

Hi,[quote user="Romy the Cat"]However, even if you did succeed to preserve dynamics in your line-level transformer then the LF cut off of this transformer will “get” you. The solution is very simple: do not run any transformer attenuators within a re...
|
|
[quote user="Thorsten"] So, at least in commonly observable and observed terms and when used as intended the S&B line transformers are notably more capable at low frequencies than your LF OPT's in the Super Milq.[/quote]
I have no doubt but ther...

Since adding the one-staging 3 channels have triggered the replacement of all magnetiks in the Super Milq’s power supplies:

Eventually, I had a chance to spend last night with up and running new Milq (no tweeters was involved at this point). As I said before, the major fight was around the MF channel and I feel I did found a good configuration where the MF channel takes a...

A month or so ago I came to an occasion to fish a large isolation transformer. It is not that I believe in isolation transformers as all my former experiments with them delivered quite gruesome sonic result. However, since the APS people are still no...

I spent many hours listening and experimenting, trying to change the signature of my mid-base channel. Everything that I'm trying suggest me that I am in at very right direction but I am still not server I would say freeze the system and do not t...

My project to add 3 one-stages channels to Super Melquiades look like progressing (it means I will have the new 15,5:1output transformers very soon) and in context of upcoming changes and, after long consideration and some tests, I desire...

I was contemplating the 6 Channel Super Melquiades conversion – it will quite a revision – and I am slowly inclining to make it not 6 Channel but 7 channels…Anyhow, the post will not be about the needs of extra 7th channel but rather about one of the...

The more I deal with 6C33C the more this tube amuses me. Couple years ago when I started to use a half of 6C33C for my upper frequency channels I wired right and left my Super Milq with half of 6C33C connected to right and left side of the tubes co...

Yes, Peter, thanks, good reading.
I research the DC offset and toroids subject as well. I think it is not as bad as it is portrayed. First of all it is not complicated to make toroids with gap, sure slightly more expensive. Also if do not save mone...

[quote user="Romy the Cat"]That sucks. I use to have a box of perhaps a dozen of YO186 but I did not see it for a while, pretty much from the time I moved to new house. I was listening today some of my “critical” reference stuff and concluded with ve...

[quote user="hagtech"]Ah, think of it this way. Imagine floating the input to your ET step-ups. Don't ground it. Let the primary and phono cartridge float. This is a similar situation but far far more sensitive. It's a m...

I do not know why people go into low-sensitive loudspeaker and they go crazy in order push the last drop out of the class A2 operation. From a different perspective the Macondo’s woofer towers with 97.5dB sensitivity are low low-sensitive loudspeaker...

Anthony, I visited you thread and glance the progress you
are going with Milq DSET. I do not exactly how you feel, I went over it myself.
Let me to tell you how I dealt with what your experience. I am not sure that my
dealing with the problem is a...
