Vincent stereo preamplifier ls1 swap
To achieve optimal modeling accuracy with the Sphere system, the microphone preamp gain should be set equally on both channels. See the Preamp Calibration section in the Installation and Configuration chapter in the Sphere Hardware and Software Guide for step by step information. Remember Me.

Already while hauling in the box I was quite surprised by its heavyweight, predominantly on one side of the box. Unpacking the amp I am further surprised by its small size! Apparently, I had not paid attention to its specs and just assumed that this amp was full width, meaning cm while in fact, its chassis is only 37,5 cm wide and its front panel adding only 1 cm to that at 38,5 cm.
The transformer housing is even smaller at 36 cm. One of the greatest features of this amp is that it can be switched between Triode and UltraLinear mode, via IR remote control! The tubes are also driven very conservatively, to allow for the best stability and longest life. Also, as hinted at with the image of the integrated amp variant above, the PrimaLuna amps can accommodate various tubes. Since I firmly believe that fewer components especially output devices make for a purer sound, I opted for the regular 4-tube DiaLogue Premium.
A very nice feature of this amp is that it sounds great from the instant that you switch it on. It becomes slightly more relaxed and expansive after 20 or so minutes, but right from the get-go, it sounds open, dynamic and smooth. How wide, you ask?
Even in UltraLinear mode this amp only provides only 36 watts with its stock EL34 tubes. Expecting a mushy sound I was overwhelmed to find that not only was the bass tight and powerful, the naturalness in tonality had also stepped up several notches. Everyone knows that tubes have their special way with voices and midrange in general and I have my fair share of experience in this field too, but considering the big transistor amp names that I also used with them I did not expect the Sabrinas to work so well with this little amp.
Apparently, this is one of those rare occasions where a magical match is made. After 20 minutes of playing time the amp was brand new involvement was raised to the point where it became hard to walk away. In spite of the low absolute power, dynamics were now seemingly even more expansive than with either of the big transistor amps, as was the soundstage.
Boy, now the Sabrinas sure rocked! Above: still attached is the anti-scratch plastic foil as I was contemplating trading up to the HP model.
So is this supposed power hungry aspect nonsense? Well, yes and no. If you play truly dynamic music such as classical pieces, very loudly, the peaks will be reproduced more compressed than with the Ayre and the Bryston.
During my normal listening sessions playing much more already compressed- soul, funk, jazz and electronic I did not become aware of any limitations of power unless really pushing it to volume levels where the neighbors might come knocking on my door. The DiaLogue Premium has a rare combination of lushness stereotypical tube and powerful dynamics not necessarily stereotypical tube.
To my ears, it sounds the opposite of compressed in a way that simply makes one switch off the brain and just enjoy the music. Smoke came out and the amp was no more. Not only did the PrimaLuna stay alive, but it also injected an impressive sense of dynamic swing and overall power into the Centaurs.
Since the Duettas are also still set up in these quarters, I could not resist giving this a go. Wow: not only did the PrimaLuna drive them, but they also made them come alive too! Bass was big and powerful, the midrange was rich and communicative and treble smooth and fluid.
This is really quite special because except for the Audio Research Ref 75 SE, all other tube amps that I tried sounded slow and overly woolly with these speakers, among them some very big names too! This points to the output impedance being quite low for the Ref75 and the PrimaLuna having a beefy power supply and output transformers.
Soundstaging is another forte of this amp, seemingly effortlessly filling the room with a big musical aura. His amp is almost new, likely just run in, so in optimal form. After switching my brain back on and comparing the PrimaLuna to the Ref 75 SE, both are definitely great amps, but there are several differences so obvious that I would not pronounce either the substitute for the other. The Ref 75 SE is unmatched in its ability to provide state of the art resolution and purity, with amazing treble delicacy and timbral accuracy along with tight and articulate bass that is not normally expected from a tube amp.
The PrimaLuna does not quite reach the same levels of refinement nor the incredibly accurate imaging as the Audio Research. The thing is: there is no such thing as the perfect audio component. Even if you spend ridiculous amounts of money, still there will be areas in which a product excels and areas in which it is less endowed. The Ref 75 SE really is superbly refined, transparent and neutral, and truly a precision instrument.
If however as a music lover you can do with a little less image specificity and delicacy, for sheer musicality it will be difficult to beat the PrimaLuna Dialogue Premium, even if you are prepared to pay a lot more. Above: with all speakers, I used the 4-ohm tap. From experience with other tube amps I know that the other taps can make a lot of difference, but usually, the 4-ohm tap is the smoothest sounding one, the higher ohm ones usually resulting in more control.
This could be different with the PrimaLuna, but as it always sounds so great, I have not yet experimented with this. Yet the PrimaLuna managed to combine various aspects that the aforementioned amps individually do so well. The PrimaLuna has much of the smoothness and body of the Bryston and much of the agility, purity and lively dynamics of the NuPrime, making for the best match with these speakers yet.
Naturally, the watt PrimaLuna does not have the ultimate muscle power of either solid state amp, but with these speakers, it easily has more power than required. In addition, while less focused and precise than the NuPrime, the PrimaLuna projects an even larger soundstage outside of the speakers.
It remains remarkable how great a tube amp can sound, but it has to be noted that the amp-speaker match is much more critical than with transistor amps and switching amps.
In this case, it is a perfect match! Now for the really ridiculous combination. Believe me or not, but the watt DiaLogue Premium actually drives the Vivids pretty well!
It does not have the ultimate bass control of the solid state amps, but it does sound nicely dynamic and punchy, and importantly, emotionally totally convincing. The soundstage is very wide and timbre very natural, quite a bit more so than with the other amps.
Ultimately there is not quite enough power to play loud transients in all their splendor, and things do get rounded off here and there when playing more demanding material. Rather amazingly the Ref 75 SE had a harder time driving the Vivids, sounding more precise, but noticeably rounded off on louder dynamic peaks than the PrimaLuna.
A nice, but equally ridiculous combination price-wise might be to use the more powerful PrimaLuna DiaLogue Premium HP with the best Gold Label tubes with these speakers. If not, then the component under review is either my personal property or that of a friend. In this case, after reading all the info online I was already so convinced of its quality that I actually already purchased the amp prior to reviewing it.
While no true substitute for the Audio Research Reference 75 SE, due to its wide speaker compatibility, I would actually rate it almost as highly. Even though the PrimaLuna tube configuration is similar to the Audio Research Push-Pull, Ultralinear , the amps have quite a different sound. All that said, the DiaLogue Premium should really be judged on its own while keeping in mind that lots can still be altered by swapping driver tubes or power tubes.
Even in its basic form with standard EL34 tubes, the DiaLogue Premium sounds very robust, large, lively and open, and very dynamic. And quite uniquely, it combines all this power and stability with a smooth and richly colorful sound. I recently divorced my wife etc.. Maybe a PrimaLuna Dialogue or Jadis tube amp? Hi Ruben, For the most part this is a matter of taste and a lot depends on how well the Wilsons are supported by the room.
Suggesting a certain brand is also not helpful as that would be a reflection of my taste, not yours. Going from my experience with the WP8, I know that pretty much any amplifier can drive them well and both transistors and tubes apply.
The latter arguably offers the best bang for the buck with the Scorpio integrated amp. It sounds sweet yet powerful. Comments are curated manually which causes them to appear with a delay.
