By looking at it this looks like a magnetostatic (isodynamic?) design rather than a ribbon. There's a Danish guy who has done good research on the subject: http://www.soundimage.dk/Different-col/Magneto.htm (you can click on "ribbon" for more in...

Well to pile up superfluous things into audio components in order to make products more expensive is not alien thing in audio. My question was not about to mock the Raven company. It might be fine TT, I do not know anything about them and I do not p...

newbie here but this interests me as i have the baby raven one. the platter of the ac is hollowed out and filled with a gel and then topped with the copper "mat". why is this important? because vibrations exists is 2 forms, s-w...

Yep KIS. I dont use tweeters at all...just run a pair of Fostex 4" per channel in a sealed box from 250 Hz to where they will go. There is a little upward tilt which Romy rightly complains about to all the gods that wil...

You must be into antiques or something. Just buy a Raven R1. It will easily outperform both the EV (which is not very good) or the Vitavox (which is good if your hearing doesn't extend over 12Khz) tweeters. Yago...

perhaps "voicing" was a poor choice of words. but i don't think there's any designer that would put a concept into production before testing it for sound quality. and then tweaking until the desired effect has been met. tw...

The Thread was written from Romy 2006, I don't know when I read it the first time but it was an eye opener for me. In a way, one of the very best Analysis ever written.
6 years later (2012) every single sentence is still valid about morons, idiots,...

There is TT out there: Raven Black Night

that has:
“3 motors arranged in an arrow formation, pointing towards the platter. Drive belt is guided through the d...

Dear Paul,Generally I can say a lot lower sound floor, You hear more detail with less compression. Very open. I compared it with Mayajima Shilabe and Ortofon Royal N, with Ortofon 12", SME 3012 and TW Raven tone arms. As you see I'm using "heavy" arm...

Wow, I never thought of that before. But you could be right. Perhaps the only section of belt contact that matters is that last inch or two before it leaves platter. Clearly the belt does not push, it can only pull. And if bel...

I've been at Munich High End Show, too.Listened to the Cessaro Horn, too, and last year- 2008- I was in that room for longer time...But honestly, based on the money you had to pay for the whole System (Raven, TW electronics, last year it was an expen...

actually this is not so much about horn loading ribbons as it is about curving them, but also horn loading. look at this horn: http://www.pioneerelectronics.com/pio/pe/images/portal/cit_3442/35960TH-4003_s.jpgnow imagine a ribbon of approximately sam...

Romy,Point taken on the Ozone issue...do the catalytic converters in the units work effectively? I do not know. There are relatively inexpensive measuring devices for it.I agree completely that they sound different. You can see in my language that I ...

[quote user="Romy the Cat"] Give me a break! Sorry, but I do not believe in all of it.

[quote user="Stitch"]… It is known for years, that the Raven has problems with motor(s) and is highly colored in reproduction abilities… [/quote] The subject of Turntables Motors is very tricky one and it turn out that Motors do affect sound very dra...

Why is Acoustic Solid so interesting to me? Well, it should be to most when you read stuff like a $1,600 Black Wood Classic model can beat out a $5,500 Super Scoutmaster model from VPI, and a $4,000 Solid One can compete with a TW Acus...

I think it is wider then just Schroeder arms. Did you see ANY discussions about the Sonic Quality of hyped products? [/quote]No. the typical audiophile has the following tatoo onto his forehead "I-buy-I-Am"[quote user="R...

I'm not convinced a constant side load on bearing is good. It causes assymetrical wear. Just seems to me a center balanced bearing with no lateral loads would be better. Merely an intuitive hunch.
As for the copper, yes, it...

In the last 10 years I had some chances to visit owners with very expensive Systems (>500.000,-- $) and all they had the same in common:
Absolutely no idea about real High End or Music reproduction and I mean non, nada, nothing, they went to a d...

All-I'm optimizing new speakers, but the deep subject matter is a little new to me. Will this work?Using a pair of Welborne Labs DRD300B SET amps (tapped 8ohms) with a 3-way passive crossover to integrate these drivers. Here is ...

The discussion was about a German Raven Turntable and what next Turntable should be chosen when the owner don't want to have it anymore....

Actually it is surprisingly interesting. It is a German company and they do a fascinating and it appears to be appealing turntable

A site visitor pointed me out the I never made an intended write up about the David Haigner horns. I just forgot about them… OK, let analyze David’s claims and his Alphahorn design. I would say right the way that I do not like the Alphahorn’s id...
