This shows the integrity of the man! I have never heard the Rudistor amps but a RP-31 is on its way to me. I bought it based on the reviews here and the quality of construction, as for me it has to look good too. This shows the extra effort that went into designing the amp. I am sure it sounds as good as it looks, if not better!
Having owned several mono block designed amps and dual mono preamps by Krell and a bemoth 200watt custom designed tube amp by Tim Parvicini, I can tell you that a dual/ mono version is always superior- tighter and extended bass, more open midrange, sweeter extended highs with air, better soundstaging with each instrument defined in its space- I could go on and on. I believe it's got something to do with the laws of Physics-you just get more current (clean power/energy) which enables it to drive the speakers/headphones better.
Look forward to hearing these favourable impressions from you guys at the Jan 30th meet.

What for????

I don't get it, if you do not consider the Rudistor amps to be in the same league of the Dr. Gilmore Dynahi (or at least the RP33) that as you stated is a old and inferior Nelson Pass topology, and that you could make, and sell for $300.00, and considering that you make, and sell, the Dynahi, for a way more than $300.00, why being so worried for other amps, and their synergy with all those headphones, if you already have the best one, or is that you are not so sure of what Gilmore desinged, and later you copy, and sell???? In other words are you satisfied with the Dynahi or not???

Man, I was yesterday listening some recordings, and honestly this amps is so transparent that I literally could hear all what was happening on the studio, any noise, any clap, even not intended to be in the recording, and just a clap to keep the pace on the music or whatever, etc...that amp is simply amazing...you will not be disapointed with the RP31...

This headphone list is very short and just two brand topology: Grado-Sennheiser. For me too poor for a objective amp evaluation.

I think that the hypotetical best headphone (that I csonsider to be the Qualia 010) can say which is the best amp for the best system.

Thinking to those cans in the list (I had the HD 650, RS-1 and PS-1), the RP33 will be incredible especially with the PS-1 and RS-1.

Best!

Hi Al,

just to tell you another epxerience, yesterday I was impressed listening a hi quality CD of Cheschy records... at one point I heard some little sounds very strange... hard to define what they was... but in a seocond time was clear: the headphone of the singers captured by the microphone (simply incredible) !!!

Best!
Nicola

I did not pose that question to you. Stay out of a question when you are not invited to answer it. I posed this question to Nik and to anyone who has the RP33 and some of the headphones I listed.

I hope this is in clear and understandable english

Those are the headphones that I have. And they are the headphones that a majority of the forums have. I consider any evaluation made with these headphones more "valuable" than impressions made with the Qualia.

The Qualia is the best in your opinion. I think opinions are debatable.

Thank you.

It doesn't say "Nik" in any place of your post, sorry, but as this thread was initiated by me, and I have all the rights to answer post and say all what I want and please on it, if you want to post your silly commnets and questions, about other things headphones and amps, not related and out of topic IMO, just open you own thread and period, in which I will not be answering anything for sure....

Sure. Keep talking...

To everyone else other than Sovkiller -

Any impressions with the HD-650, Alessandro MS2, Grado PS1, MS-Pro, RS-1, Beyer DT-880 ??

If anyone has owned an RP5 before moving to the RP33 please let me know what you think (hybrid vs. fill blown SS)

 

[Sovkiller]

Sure I will keep on talking, here is some of Rudi's comments about some of my questions about your posts....

Just to clear things a little bit, here is the answer from Rudi himself, sorry but I asked him, becasue I do like, and need to know certain things...hope this clear things a little bit, and hope this bring some light to this debate...and shows who is right or wrong.

".....It is impossible that anybody has the schematics of the RP33, it has never been published by me, not anybody else.
But non of amps in the RP series is based on any Nelson Pass schematics, or topologies, for the simple reason that I have developed the heart of the SS and RP series, years before the Nelson publication of his Zen amp. BTW both designs (Nelson’s and mine) are based on applications of the classic theory of Class-A solid state design, and they are similar the same way all the cars are similar, since they are based on the same principles....BTW, the RP010 is completelly different..."

 

[gsferrari]

I never said nelson pass design was bad. It is an awesome design and I am actually happy to see it...or some "version" of it...in a Rudistor amp. I can understand what Rudi is saying...

There is only "so much" you can do with transistors, op-amps, caps, resistors

Ultimately things are going to look the same and when they start looking the same you can safely assume that the best solution has been found and everyone can adopt it.

No offense intended to Rudi. Only a listening test will prove if it is indeed the best amplifier that will make the Max, Prehead, Dynahi everything sound inferior

No, you never said that the Nelson Pass designs are good or bad, but you do said that according to the schematics "you have, the RP33 is a Nelson Pass design all the way", which is not true at all, first because you have no schematics of this amp, and second because they are not a Nelson Pass design, neither all the way, nor any version of them, simply those topologies were designed before Nelson Pass published his, and "maybe" (as I'm not not sure of that) before he designed his.....period...

BTW nobody had stated here that the RP33 amp is better than any of those amps you are mentioning neither, at least not me, as I have not heard those amps, but at least cross out the Max, it is out of that contest, simply becasue according to the members who had used them, non of the headroom amps match very well with the CD3000, and OTOH the RP33 is one of the best matches for it, a point in its favor IMO...

When I said that $50 was expensive for shipping...I didn't realize that it Rudi who was selling the amp. I thought it was someone else who had bought it and was selling it. When I saw "Italy" as the location, I assumed it was a local buyer of Rudistor's. Sorry to make anyone explain.
I recently sent a 4 lb box (RA-1) to Australia (2 weeks ago), fastest shipping...I think it was called Global Priority, and it cost $14. They promised me 4 business days, but it took 8.

The question as to whether or not I have the schematics of this amp can only be anwered by me. Wait till clone RP33's pop up for $300.00 or less

Dude - look at the board. It takes roughly 15 minutes to draw the schematics and around 1.5 hours to build the clone if you have the parts

But I will not ruin your christmas sov - enjoy it

Yep that's right...!!! But it is really doubtful, that if you have never seen the amp, as one of the firsts in US is the one I have here, and OTOH you are looking for information on the sound (what indicates that nobody that you knows have it neither) and OTOH as the schematic has never been published, I don't know but it is really hard to believe that you have a clue of what is inside this amp, dude, sorry to be so honest with you....

About the Xmas, nobody will do it for sure: "Jesus is the reason of the season" don't forget that, he will not let anybody ruin that, not even the "G" bros....
