Devo, the GM-100 for sure is a good triode to get 160 watts
output power in A1. Still, it would be a good chose, from my point of view,
ONLY from a prospect of embracing as good DIY audio project. There is nothing wrong
then to do the good DIY aud...

I spend quite a few hours playing with the new channel trying to ingrate into Macondo but so far not successful.
Since the new channel and the Macondo upperbass horn have identical sensitively and identical impedance I figured that I would drive it...

Paul, l I have written about it somewhere: the passive speaker-level crossovers on bass channels are no good. Marko has 250Hz that with 3rd order would be around 10mH and 2mH. With air core then would be very large coils with huge amount of DCR – ver...

I do not know which core and wire materials I shell need, I need to consult with my transformer people for that. As the starting point I plan to use that:

I was asked a few days ago what I think about Zandèn new CD player and I replied that I do not think about it.

Paul McGowan, the head of PS Audio send his newsletter with his comments about SACD. The comments are childish and in many way absolutely ignorant. I hate what the industry professionals twist the facts and go into pure falsification in order to ...

Romy,I might have overlooked something on your site but I understand that your ULF amp is driven directly by the preamp line stage. If that is the case, you may want to consider an old technique for integrating subwoofers and drive your ULF amp w...

I'm following with interest the thread and must say that I'm baffled: Goto's "instructions" are - SIMPLY said - a mix between non-existent and wrong... I love what Goto's did in my system... BUT I think I did more with "my own" care, "my own" taste, ...

Congratulations on the build! anthony wrote: Yours uses all toroids, or mostly so, which are more efficient than the EI that I use.
Why have you chosen EI vs toroids? The latter emit less.
Cheers,

Hi Romy, I recently heard the smallest Cessaro and while I felt that the bass was not adequate for long term satisfaction it was also not a total disaster. From the midbass on up; however, the speaker is simply superb and one of the very best h...

Not completely objective but still “some kind of test” for the bit’s resolution. For those of us who use Pacific Microsonics processors it is easy to see of the file was original. When pacific does A/D it injects the HDCD code. It does it in any ...

While Dima is cooking the Super Zarathustra I figure out that I would need some test speaker to be able to observe the preliminary results. I would not be able to drive the multi-channel Macondo with a single full range amplifier, so I need something...

Chris, I have no experience with good sounding SS amplifier that might drive high sensitive horns. I also have no expertise to build such an amp. From what I trued before I have learned that in order to sound more or less acceptable the SS should run...

If to look at the Melquiades schematic in the channel “A” you will see 78H first order low pass filter.

Yes a few ridiculous requests and statements there indeed. Full ridiculousness intended.
I know Dunnoy needs a lot of power and low impedance amp. My aims are not the same as yours here as I'm not concerned to...

While one has some quibbles with Romy's post, and must also ignore his
sometimes bilious tone, the principal thesis is grand indeed: The
process that led to a playback industry where a $50 tabletop (in my case
a fine $180 Sony "minisystem") sou...

I always said that regular audio-freaks, who mostly unprovoked bend themselves in demonstration of the excessive and stupid devotion to audio manufactures, are the worst case. Ironically that “devotion” is not what the manufactures demand but the obs...

Romy,
Thank you for sharing the link!
The second part is better!

We only use the Beringher for bass under 100 hz, driven by the main amp.
We tried a lot of different solutions, including analog active xovers, the DCX is cl...

I’m glad you talk about geometry, but to respond to this I have to refer to other brands. I will only talk about facts and hope it’s not offending anybody.My basic point is: the flare rate has to be coherent right from the entrance of phase plugs. In...
