For the last 2 days a spent a lot of effort to learn about the power regeneration by frequency converters. That is very fascinating subject, though I have no idea to what kind sonic result it might lead. It is very much possible that my new place...

[quote user="decoud"]For what it is worth, unless you are irradiating a concert hall, the SH50 is perfectly adequately driven by a 15W single 845-based SET, and I will shortly find out what it sounds like with a full range Melq. [/quote]Probably 15W ...

[quote user="Edgar="]Not Amplitude. It's the rock solid phase linearity. It feels like a brick wall all the way up and down. I haven't looked at any graphs and haven't measured anything but that is my guess. There is no question of the great tone of ...

Hello Romy and others,Ive been away for a long time taking care of my health but i'm back with renewed interest. I am moving to a new house in the future and have plans for a dedicated music room (and an occasional movie) The space is however much sm...

"You need to realise that the physically larger a Transformer becomes the narrower the available bandwidth for a given construction. Due to the need to handle a lot of "magnetic bias" SE Output transformers become very large, physicall...

There are many threads on my site where I covered the subjects of Tweeter for my Macondo and particularly the moment of integration the tweeters with Vitavox S2 compression driver. Since a few months ago I altered my idea to use the EV T-350 tweeter ...

Romy, it sounds like, as usual, you have covered a lot of ground already before you put out your first questions about ribbons.FWIW, I presently use Arum Cantus G2Si ribbons, phasing them in at 10k Hz to supplement the Lowther DX4's dreaded...

Hi,[quote user="cv"]RE: the Slagle autoformers and their lower than S&B inductance, that's a deliberate design choice on his part.[/quote] I am aware of that, however DS does not make that unneccesarily clear to potential customers... [quote...

This is about the Focal Utopia TN51 tweeter....
It is hard to imagine not much I like this tweeter, in fact there is something insanely beautiful in this tweeter and from a certain perspective (narrow-certain) I like it even more then the HF o...

I usually do not cruse across DIY forums unless someone folks about me. Here it was - at some Russian DIY site they translated my article “6C33C survival guide” that made me to see what they have in there. One article from their site attracted my...

Rakesh, I moved your post to this thread as I feel it is more relevant here, I hope you do not mind. You ask yours the very same question that I ask myself. I do not have definitive answers to them:

[quote user="Romy the Cat"] For a casual observer it might appear that I am constantly fought with my ULF, finding and loosing better and worse configurations. It might be so but I have a very strong sense of objective of what I would like to ac...

Actually I don't find it surprising that engineers don't realize the sonic effects of their engineering. Remember all the indignant articles and letters they wrote about how great solid state amps with low THD sound and how lousy tubes are. In the ca...

Hi,
Thanks for the info about transformers. It is as I expected, however, that these passive devices are not passive sonically at all. I agree with you that the higher quality of the transformers should lessen the effects I noted (if not elimi...

Any time Adrian, email me privately and we will set it up. I don't mind if you report your impressions if you don't mind me doing the same.You're probably correct in your suspicion, different strokes for different folks. Objectively spe...

Looking at the drivers, and the range of adjustments, it appears that Wilson have done some things that make more sense than usual, at least to me. The MTM drivers can easily be set for "time alignment", which should help to cope with Wilson's "noto...

I have been playing around with speakers for a long time, and things started snapping when I got into horns. I have a system right now with an upperbass horn from 140 hz turned form MDF up to around 700 hz, to another horn, and another and a super t...

Aura made their 1808 driver in 80s and most of the 90s and it was wonderful. It had huge high-temperature neodymium magnet, unique magnet geometry with underhung 4" edgewound aluminum voice coil. It was the only 18-inch...

To be honest, I think that ANY stereo system gets in the way of the music - regardless of the amount of channels.Let us jump back to the monaural records/radio years. At that time, we had one choice and were very satisfied in being able to play back ...

I don't understand why people are using the flywheel with the same thread coming off the motor to go around both the turntable platter and the flywheel. I also don't get why the flywheel is supposed to be used with a slipping thread at all. To make...

Hi everyone,It is quite ironic that the day I hear from Fane telling me that the Fane 8Ms are finally ready, I should receive this update from my horn maker maestro. Russ Collinson of Layers of Beauty. Russ, if you ever read this here, please take a ...

Ehh, what do you know – I subscribe the TAS last week. I think I did it 7 years back but I was wondering if it be some kind of fun. I got my first issues a few days back and made an attempt to read it. Funny but I do not exactly understand what they ...

At some point last year, after I had been offered an opportunity to buy some Vitavox S2 drivers from someone in Paris, and some S3s from Germany, I decided to approach Mike Harvey of Octave Audio, AKA Vitavox Hifi, to get some information about how I...

First of all, season's greetings to all. I have been thinking about this issue for a few months now and was reluctant to post a question in case it was premature! There must always be some niggling doubt whether any real estate adventure will materia...

Hy Paul, I agree with your comment about the tone of the passive radiator if it runs to the mid range. This is the point of the SS8565. the combo of the crazy stiff cone and the special surround works phenomenally well to stay linear. It is even bett...
