Since the “no tilting rule” is one of the Macondo’s Axioms: (#2 - “All channels shell have strictly parallel axis”) then I would like to defend it.

There are many threads on my site where I covered the subjects of Tweeter for my Macondo and particularly the moment of integration the tweeters with Vitavox S2 compression driver. Since a few months ago I altered my idea to use the EV T-350 tweeter ...

Jessie,
I was about to replay to your post and suddenly John Hasquin posted his reply that said exactly what I meant to say. In fact he has much more credential to assess the validity of you attempts then me as he actually build the horns. In additi...

Ok... Assuming the lack of time alignment is compensated for via a DSP:
There are likely large chunks of the frequency spectrum that go un addressed, and equally large chunks that are mall-addressed.
I would say that there are two main ranges ...

[quote user="drdna"]I have found the next obvious glaring problem, which is contributing to the muddy sound I described earlier. There is a mismatch between the two channels. The right channel is very slightly softer than the left with a ...

It took for us, for the people with brains and ears, a few years to explain to the foolish audiophiles the artificiality of their soundstage objectives. Six years ago when I was tiring explaining to the audio-zombies that soundstage is juts a surroga...

[quote user="rafaroxlm"]As you may know the 7788 is a high transconductance pentode which should in theory be able to give higher audio resolution than say 12AX7, 6072 tubes in tube mic pre designs. On search here the 7788 was mention...

With the recent changes on my configuration changes and employing the “End of the Live Phonostage”, in duty I re-thinked my analog playback. I got rid to arms and one deck, changed the mapping between the arms and phonostages and ended up with quite ...

Here are some commentaries regarding my “End of Life" Phonostage.
The name of this phonostage derives from many factors. I am forty, winch it more or less a half live and in the first half I was playing a lot with different audio toys. The last 10 y...

[quote user="hagtech"]First, it seems like the tubes are starved. They are running very low current. The 12AX7 is also at low voltage. I'm guessing they are running at about 0.3mA at 65V plate. This operating point is way down...
