and was just learning the new room and making changes, I was also

My feeling about perfect listening chair has altered lately – I need another sit at my listening chair, so it kind of becoming a listening couch instead of listening chair. As much efforts I spent to explain to my girlfriend about time alignment and ...

I have identified a direction for my next speaker system. Whether it is a good one or not is a different topic -- I think it's a good one because I've lived with my current horn system for 10 years and have since developed an understanding of it's st...

Yes, it turned out to be the emails from GOTO importer. I am not completely understood if the horn at the picture above is an official GOTO product. The Ming Su said that the horn was build locally by Jeffrey Jackson with the support of GOTO but then...

These days I am traveling frequently and relegated to listening to music via headphones and "portable" sources. I will briefly post my brief journey as a personal log. It might provide a starting point for those who might find themselves in the same ...

Romy,
Funny stuff... especially the the AN piece. Equally surprised octopodes ? Brilliant !
As for the Bruce Edgar post ? Not as funny. And it's off base.
The Titan II system has a straight axis upper bass horn instead of a folded upper bas...

It wound up taking 9 weeks to get my re-built cartridge back from/through the Ortofon DK/USA consortium, and then I let the re-built cartridge just sit there in is box for another 2 weeks. When I finally went to re-mount it, I managed to snap a ver...

[quote]might I ask why[/quote]1.)the bass will be pretty coloured...mouth not large enough for proper bass response..

A few days back I visited an audio person who demonstrated to me his experiments with extreme lateral deviation of souses. Regardless if I agree or not what he was doing or trying to do the demonstration has an unexpected result. One day I was driv...

Thanks for the kind words Romy. I am enjoying taking my time with this project and getting things just right. It sure helps when there is little development involved, just duplication more or less. Development may come later as I impose my exp...
