Wojtek,
I do not think that Martin has any time alignment strategy. You see, the necessity for time alignment is a basic fundamental principle, and particularly in horns that spin phase like helicopter. However, in many instances the horns are juts ...

[quote user="Romy the Cat"]Now my midrange channel need no upper range diffusion and now I feel that the result I’m getting from T350 is too soft and too transiently slow for S2. So, I kind of very mildly begin to look out there and to try top fugue ...

Dear Romy,
well the horns are actually not designed for HF. The intended working range is up to 5-700. But since we use low Q, only second order filters we want to have a rather large overlap in the crossover region and a fairly even pattern over ...
|
|
Dear Romy,OK, some more about the midbass.Well, it was not really a surprise to us that the horn without the phase plug was dissapointing. Without the plug we had a horn that was a bit too short, had too large front cavity and less compression than w...

I must have missed out on how you regulate gain to or from each or any of several "channels"/pass bands, Romy. I can remember years ago trying lots of EQ things to get "Flat Frequency Response" and finally giving up on all of it, including...

After dealing with my tuner pick digital noise from my AD and DA, and particularly from Lavry DAC, I loaded Lavry with quite substantial amount of ferrite anti-RF filters:

Figuring out how to switch REL Precedent’s IM bandwidth to more suitable for Stereo operation I was wondering about something else. The 250kHz window though which the REL Precedent looks to the FM band is might be fine for DXing or having good select...

I would like to offers some thoughts about possible avenues for Pure Power 2000 improvements. Those thoughts are no specific to the recent November-December events and have broader generic implication. I initially intended to write it to Pure Po...

I have a problem with how you are using the english language, Romy. You are using an absolute word (like absolute) to mean something you have invented and it is a relative thing. This for me won't do. I understand more or less what ...

It is nothing to do with Wisdom. It is my principle of application of “cost” as a common sense design tool. I do not bitch that Duelund caps are expensive. I just try to find a rational solution for using them that would embrace their price. My ...

[quote user="Romy the Cat"]Yep, Telstar. The 1547 was use in Sony and Teac CD players and believe the first CD-SACD machines used that chip. I know very little about those chips and have none of my personal experience to deal with all of it. The reas...

[quote user="alexd"] The issue of properly handling FM signal is related to the capabilities of your A/D converters. Your A/D converters have analog and digital anti-aliasing filters and delta-sigma modulated A/D chips. [/quote]

Dear Romy,
A. Recordings of different quality are worthwhile. Let's take three examples:
1) A stereo recording that you feel is as good as it gets.2) A mono recording of a beautiful piece of music that is well played.3) A stereo re...
