Found some interesting comments on an independent web site, Twogoodears.
I'll copy it, it is from 2009 with original lines from Arthur Salvatore and a comment from Stefano Bertocello - Twogoodears owner -, we will n...

[quote user="Antonio J."]Thanks a lot, I've forwarded to him your answers, let's see what he says. I have tried Mundorfs in some critical places in the integrated tube amp I'm using now and they are pretty good, expensive, but not at the level of tho...

Yes, you are right it is rather my negative prejudges and I should not proud about it. It perfectly possible that Bend is a fine performer…. Still, it is a transformer and no mater what you do is a band-pass filter. It is still inductance at the bott...

I finally set it up new Tannoy Red best Twitters. They are sealed irregular shape and purely themselves do not sound bad. They do not have the full range feeling as they had with passive radiator and had a typical red sound of late Autumn leaves....

[quote user="decoud"]This is a synergy horn, a topology that Danley has a patent on, I believe, and certainly the most expertise. There have been extensive discussions on this site about it, including Romy's theoretical objections to the idea. In a s...

If we are taking about multi-way horn-loaded acoustic system then in my view is it very important to plan the development in a specific order. Any deviations from the order are perfectly fine but they will affect cost/time/efforts of the project. Thi...

Hope it isn't the case, but it sounds like you have just described "the best sound" (or, in any case, the sound you're after) from Remedios as being limited to 90 dB SPL, through your wide range of experiments with the basic configuration. I don't re...

Thanks Bill! I'll prefer to use something more elegant than the putty (which will harden with time).
I go with the passive radiator not double Reds. My space is pretty small so I hope a single Red will do.

N-set, besides the fact that you are struggling with whatever crossover or any other problem you have I wonder what's your feeling about the difference in a sound this configuration offer? Is I understand you have B2, Reds, default crossover and ...

[quote user="Marc HENRY"]hi all,thanks for your interest !yes the frame is curved, HF and MF are //yes there is a phase plug in the bass horn. This cover 80-300Hz.there is a separate infra-bass section, covering 20-80Hz.images of the bass phase p...

Can someone help me to calculate the input impedance of the 6-chaenal Milq?It is cannot be measured as a regular DC impedance as it is affected by the active impedance and the by positive and negative voltages from the bias supply and the bias compen...

FWIW I tried quite a few isolation and power conditioner products over the years. The only ones that I still use and feel do more good than harm are the now discontinued PS Audio Ultimate Outlets. They are simply good quality baluns. The advantage ...

Is there any abstract value to going for a preamp with a stronger output if you're using a passive xo at line level?I'd prefer to answer this question myself but i really don't have the budget to be swapping amps.How does a PLLXO interact with a non-...

Not to go overboard after only 2 days of operation, but the Bent TAP (transformer-attenuator [passive] pre-amp) is a pip in my system. It is as "neutral" as anything I am familiar with, compared to by-pass (with CD). I love havi...

and not very encouraging. The set up was as follows: a Lowther ex4 playing from ~12k down in a big ~100Hz tratrix. A Murata up on top, and a 15" Beyma on the bottom. The Beyma is in an Onken so the results may not be fully indicative of performance i...

[quote user="Romy the Cat"]The line-level crossovers work against fixed impedance and therefore the crossover point and the time alignment does not fluctuate along with reactance of the drivers.[/quote]Okay, maybe this is a dumb question, but why wou...

I went for a better amp for MiniMe because it’s summer, hot and I am listening MiniMe more than Macondo.
But!
As I said before the MiniMe post talks with Macondo (when I turn Macondo on) and it forces me to plug the MiniMe port with a pile...

Meeeeeowwwwww,[quote user="Romy the Cat"]Among the imperfection I would mention the mains voltage fluctuation. It could be fixed only by regulation with all negative sonic consequences of regulation.[/quote]I find this comment most illuminating.I can...

Something I see a lot of in studios is the "distribution amplifier", that joins and splits the audio (and/or "video") signals into any number of channels. I believe I want buffering, but I am not ready to track and impliment the "balanced" configura...

nautilus981, I do not care too much about passive attenuators or about anybody comments on them. I do not use them and I advocate do not use them. I do not have plans to publics Zarathustra circuits. It is Dima’s circuits and I will live it up to him...

KOTriode, I was not criticizing your DAC, whatever it is. I was saying that system-design-wise if your preamp was able to inflict such a dramatic change in Sound then in my view it just highlighted the problem with DAC. Take another DAC, or any comme...

Anthony, congrats on your amazing progress! I know how hard it is to carve out time for this stuff! I see you are looking for gain from your pre-amp, which makes me wonder if you have been using the passive Placette, as opposed to the active unit, wh...
