If you go over enthusiastic with the volume control you can hear the sound stage shrink and it is the warning to stop, back of a bit you are back in action.ħ. Do we hear the orchestra that way live ?Ħ. What I meant is play a well recorded large orchestral music you hear the violins, the Violas and the chellos from L - C - R but some amps can give you the precise point where each group of instruments starts and ends.

Imaging is not razor sharp or can also be called more natural !. Width of the sound stage is also fine, goes beyond the sides of the speakers. Soundstage a bit forward and not lacking in depth. I am using a MA GR20 floorstander and found that 35W is controlling the speakers well.Ĥ. It is warm, but not the usual colouring you hear from older tube amps. The sound produced gives you the impression of a more powerful one. I am having the one with Phono stage, good VFM product so you will connecting a VFM vinyl source.ģ. Very good amp, yet to see a competitor below Rs. I was listening to a Prologue one for the last 5 days and would like to share my experience with it.ġ. We always say: sit, listen to the systems and trust your own ears. The One and Two have different characters, and certainly under different circumstances, they both find 'different' owners.

But some people think sometimes it is too big and that means I have to tell that everything is 'in the combination'. The Two sounds also -with the right speaker of course- very open and like sound from heaven (for example with the newest ProAc's and the old Ensemble PA1). But in general you can say that the Two compared to the One shows a little bit more power, a bit more 'character', a bit more ease. The sound: of course heavily depending on what else is connected. They are different! The design is basically the same, the tubes are different, the rectifying is different (PL One simple bridge, PL Two 4 'best' diodes), some capacitors (there were usefull) are different in the Two (The Two uses SOLEN where usefull). First of all I do not think you can say The One is better or the Two is better. Are you from India? If so, how can we get the maximum of information about the market in this big country? Yes, we have a small importer in India who wants to grow with the line. and as said the Adaptive (!) Auto Bias is an important factor for the improved sound of the circuit. It is more than just replacing a battery. It is true that some people can re-adjust the bias, but we do not want to limit the ownership of PrimaLuna amps to those few people and we do not want to create dangerous situations for the others. Best possible control of the bias, without loss of power and till 50% less distortion. Some (the important) capacitors are higher grade in the Two and we use special diodes instead of standard rectifier bridge.Ī very important factor in both these amps as well as in the upcoming Four and Five is the Adaptive Auto Bias board. ProLogue One and Two are basically the same design, except for the tubes of course. The Audio-industry is a community where people 'talk' often more than 'listen'. Yes, correct information is often difficult to get. Preamp and stereo-poweramps will be introduced in April, mono-amps are planned for june. The TA-30/35 is no longer in production and the chassis we use is our PrimaLuna exclusive.

So little it does not have a negative effect!! This way of biasing is easier of course (you don't have to look at it), does not take any power away that you need for your music signal and further the distortion can become till 50% lower! Also some parts in the design are upgrade (other-better and matched outputtransformers, some changes in capacitor and diodes). A little bit of help when needed, so to say. As I tried to say in German: it's not just AutoBias, it is ADAPTIVE Autobias, which means that the musicsignal has a slight influence on the biassetting. Sorry, I just noticed the rest of the mail is in English. Das Chassis ist jetzt PrimaLuna exclusive. Weiter sind noch einige Änderungen daran (Ausgangstransformatore sind anders!!, einige Condensatoren sind geändert, wie die Diode). Das macht eine bessere Wiedergabe, keine Verlust in 'power' un bis 50% weniger Verzerrung. Das heisst dass die Bias nicht unbedingt FEST ist, aber auch -ein wenig- Signalabhängig.
