1)      I would like to try amorphous core foe my LF transformer. I know, I know, the amorphous core is not LF core but I know what I hear and if I found somebody who would be able to make for me dedicated amorphous LF transformer then I would try.

5)      Changing my LF section, rewirering all 12 drivers in parallel and consequential introduction of another 1.3R dedicated LF output transformer. I see a lot of benefits in a situation when my entire set of LF drivers are connected in parallel. If I have a space that I would gladly add as few more drivers to my line array….

I kind of wonder if I really would like to go there.

There are no questions in my mind that reconnecting the drivers in parallel will be beneficial. There are no questions in my mind that amorphous LF transformer will be beneficial, particularly if to make it to drive the set of the paralleled drivers. I need nothing to reconnect the driver in parallel – a few hours work and I will be though. I have found a very large chuck of amorphous core; have the transformer winder and the person who can assist me with the design. The cost of the project is mandible and nothing prevents to go there.

Still, I am hesitant. Tow aspect bothers me: one technical and one psychological.

The technical aspect is following: going with a core as fast as amorphous is it means that my LF-only large transformer with enormous inductance and with no sections still will have response all the way to 20kH… and that mean that I would need to go for second order filter on my woofer towers. I would like to found a way to restrict the HF extension of the LF channel without putting the second order low-pass on the bass.

The psychological aspect is: I do not want to do it anymore. My initial objectives with Macondo and Melquiades were to get where I would like to go with my demands considering the non-existence of the supplies. It took a few years, I did obtained the result that I feel comfortable - I relay would like to quit audio in the way how I practiced it for the last few years. I am glad what I did but since whatever I got is good “as is” I would like just to “use audio” instead of “building audio”.  I never had explicit interest in DIY for sake of DIY and always tried to buy intend of doing the things… My involvement in Macondo/Melquiades project put me in heavy DIY rotation – I enjoy the result but I do not particulars care or like the process.

If to change the transformer were just plug and play task then I do not mind to try it. However with the complexity of Macondo/Melquiades tandem I am afraid that it might be another month projects: to re-EQ the channels, to put the second order filters, to re-normalize the bias supply in Milq, and so on… I would not even mention that the woofer section and the Milq are dam heavy and I really do not look at the prospects to shovel them again.

I think I am getting older or whatever… At this point I would like just turn the system “on” and “off” and I would like do not “fuck” with it anymore, it has been “fucked” enough. I still have some minor ideas and micro-projects on pipeline of my mind but I think at this point I do not want to undertake any major projects. Let see how my future moods will decide for me but for now the “Macavity's not there”
