Romy,
Air core is ok, but. 1. Self inductance in an unmitigated field clumps. You can easily see this by unwinding a hockey puck style air core inductor and measuring the inductance with each turn removed. Never will you have the smooth loss of indu...

I do not have lot of experience with TAD cone drivers but there is a thing bout then that always afraid.
A few years ago I was at demonstration of Model-1, the TAD’s $50,000 flagman model and it had very strange feeling – the speakers sounded surpri...

Zero phase filtering would not require a reference: the signal is just run through the filter in forward and reverse. But there is another filter to consider here, a physiological filter - presbyacusis - that means Yamamura's hearing threshold above ...

[quote user="guy sergeant"] Again I get the impression that attempting to link 'serious music' as a pre-requisite to 'serious playback' is over intellectualising matters. … The equipment, of course, doesn't know what kind of noise it is being asked t...

Hi Romy, I had a background system for a while using either Kef 103.2 or tannoy gold 15¨ and McIntosh MC2205. I don't know anything about the other McIntosh gear but this particular amp had a reputation amongst french vintage nuts. My old Threshold...

Rony,
There are two possibilities as I can see them.
First is that your new hybrid amp just simply better then you former amp. Between us in case of Threshold, Jeff Rowland or McIntoshes it would not be so hard to come by to a better am, not to me...

I received an email from a visitor who is involved into the electricity fight and he pointed out that my hypothesis might or might not be accurate only in context of eliminated large distortions. According to him the very high levels of harmonic dist...

[quote user="Romy the Cat"]I had today a conversation with RAAL’s Alex and he pinched to me a very interesting idea. He feels that I attenuate the outpit of my “Water Drop” too much. I have no doubts that I attenuate it as much as necessary and Alex ...

I have not heard the Heils with all possible amps, but to my ears they are equally unequivocal with Tone and Dynamics, once their (rather low) "threshold" is reached. At least with respect to dynamics, this seems like the opposite of what one would ...

When I think back to some of the products made over the years I realize that neither we nor the manufacturers really know what makes something sound good. Some of the early pieces made by (and I hope Roman forgives me here) Pass, Van den Hul, C...

This is always good advice, to get to know the character of the phono stage. Because my favorite cartridges are not low voltage (I use Decca London Jubilee and Reference) I have never had a need for the ET SU-1 step up unit. In fact, I had this in my...

Hi Keith and congratulations for your new babies... I'm truly jealous of your room size.Me too, as I previously wrote, assembled a VERY similar rig, vastly inferior to you welded supports, any, using the same approach: S-150, S-3000 and S-400, respec...

[quote user="Romy the Cat"][quote user="drdna"] Try a simple experiment. Connect only one driver at a time. Listen only to the ribbon tweeters. Now listen only to the woofers. Etc. Can you distinguish different heights for the image? [/quote] Of caus...

Yes, in case of tube DC coupling line stabilization is desirable but it would serve only practical aspect of locking the operation point of output tube. The way HOW the line was stabilized very much might affect negatively the way how the whole ampli...

[quote user="Jorge"] I have never found the law of diminishing returns to apply to audio! Going crazy always sounds better… [/quote]
Jorge, we need to have a perspective about those things. With exception of oxric’s episode, who still is not...

I can empathize with your fascination on how a piano might influence the quality of playback in your home. A grand or large upright like a Steinway K52 has a resonating sound board 6 feet long or more. A Steinway Model D concert grand sound board i...

[quote user="Romy the Cat"]I very much insist on the fact that I do not retrieve my position on this mater. The relationship between a ‘content loaded music’ and capacity of a 'serious playback' is the only mater that counts and this is the threshold...

Hi,Have peope heard any of the new generation hybrid amps out there? I have often such miserable power to my home that about half the time it was useless to listen to my SET tube system. I always had a back-up solid-state amp to use when I could...

This subject I complex and talking about it we should not take out of aim that fact that we are talking explicitly about audio applications. If so then let admit that friendship with various audio people severally cloud our views and rational of our ...

Good points. Romy, you can throw as much money at this problem as you like but you need to face the reality that some of your gear is going to get trashed in a move. If I were you, would make a quick list of the stuff that needs to be moved, noting t...

In fact, digital recording allows the industry to process easily every musical material (a very powerful exchange-tool). Unfortunately, digital recordings are also highly corruptible in the musical-expresive potential as you point...

Ok, let dive a little bit further into my examination of the subject of Lamm ML3
What is important is to undusted that my view less targets the Lamm ML3 but rather it targets the ML3 as a representative of entire class of amplifiers. When I to...
