When I would have unlimited money I would buy the XS300 blind. For me it is that simple and clear. I owned the XP-20 for over 2 years of time. It is a very good pre-amp but I was not 100% convinced. That is why I always say: Pass Labs make stunning amp and very good pre amp, not stunning. I didn't listen to the XS pre amp. I said to Desmond that I think Pass labs should create a new preamp including roomcorrection. I have done a lot of visits from 2005 till 2007 at people with sets between 10.000 euro and more than 150.000 euro. Many had acoustic problems. Often the endresults were not that good. You can spend a lot of money on audio but the acoustics often have a big influence on the overal sound.
Till 2010 I always had very expensive stereosets worth till about 95000 euro. I liked surround as well, but I had problems with the qualoity it gives. Until I bought an Onkyo 808 just for fun as a second set beside my stereo set. I found out that it could create a deep and wide stage. Until that Primare was the cheapest brand I sold what is capable of creating a 3 dimensional stage. I sold brands like: Marantz, Denon, Cambridge, NAD, Rotel and Arcm for over 8 years of time. I know their properties very well. For me they are 2 dimensional brands. Onkyo can build a much wider and deeper stage than all these brands. You need speakers which can build a wide and deep stage, because without it the depth is all gone. These days I sell a lot of Monitor Audio. The reason is very simple; it is the only brand in the world which cheapest spakers till the Platinum series who all can build a wide and deep stage. For the first time i can sell 3 dimensional sound to many many people. Because all shops sell 2 dimensional sound for these prices.
In 2010 I started to use Audyssey. In the past I sold Tact/Lyngdorf, but their roomcorrection system is fully useless for highend. I found out that you loose a lot of dynamic when you measure like the way Audyssey usses it. 2 years ago i found out that I have a photographic memory in sound. Within 10 seconds when I use a number I know well, I know were all instruments are, hom much depth, resolution and how big the instruments are. When you change a part in the system I can compare the new situation with the old one. In my head I can put them beside eachother. I know which one is better and why?
I am also an Audyssey installer, so I use and sell Audyssey Pro. And now comes the key. In my head I had thoughts about measuring more dynamics/resolution. So what I did was measuring at different places and heights. I created my own way of measuring, the results were superior to the Audyssey way in every aspect. I learned to use the system form a highend perspective. Thta is totally different than how Audyssey uses it. Thise people are smart, but do not have highend skills and have no idea about the sound and proportion of instruments and voices.
With a Onkyo PR-SC5509 with my way of measurment I outperfom a Pass Labs XP-20 with a Pass Labs poweramp. So what are the differences?
- I can play a lot louder compared to the XP-20 before the needle starts to move.
- There is more resolution. For example; the articulation of voices is a lot more open and clear. You hear breathing, moving lips, word endings on a sss, ttt or th so much better.
- Instruments and voices are more physical toucable. You hear 2nd and 3th voices on a recording more loud and clear.
- more speed and better dynamics.
- a higher blacklevel what make instrtuments and voices much more palpable.
- I can create my own targetcurves. I read articles about humanhearing. I adapted the targetcirves after the information about human hearing. Beside a much better articulation I also created to listen to the edge of a voice. I compared recordings with my system and highend systems of clients. The edge of a voice was not noticable at there set. They became frustrated that I had so much more details.
Audyssey pro is a lot more than only roomcorrection, they use sustems like Audyssey EQ and volume what give you details which are not there even with expensive pre amps. The volume of the right and left speaker is always identical. There is more, I also created what I call: stealth low freq. In the past I sold many Rel subwoofers. Also the more expensive ones. To be honest they were to slow and You did not have a perfect integration. I always found subwoofers fully useless for stereo use. At all the people who use Rel and Velodyne subwoofers, even with Revel subwoofers I di not hear the level I was hoping for. But the Monitor Audio PLW-15 and my way of Audyssey Pro changed it all. The PLW-15 uses a lowfreq unit of 15 ich made of ceramics and alluminium. This makes the respons and timing a lot better than the REL and Velodyne subwoofers. In the past we used the rel subwoofers till max 60-70 hz. Because they were too slow to be used at higher freq. From 80hz low freq become palpable. Cause of the much faster response of the PLW-15 I did test it at much higher freq. I found out that I can easily use it till 140hz without stress. I use a Purist Audio powercable and a new Audioquest pure silver Wild Dog interconnect. ( the new reference for subwoofercables) Thes cables give the subwoofer an even higher stealth integration level.
So what is stealth low freq/steatlth integration? This is when a subwoofer fully dissapears ( at a big audio show last year were I was the absolute sound with my own system people often said: why you do not use your subwoofer: I said what you hear is stealth integration. It was new for all people even for shopowners who had a sho in audio for a long time. Now you even hear and feel the energy were it is on the recording. This was what I dreamed of and now it was there. When I play a song with a double bass or big drum on the left side, you hear and feel the energy comming from there. Even this is 2,5 metres from were the subwoofer is standing. A distributer in highend audio ( Wadia/Sonus Faber/ Audio research/ Wilson/Transparent/Revel) who is a surround specialist as wel said: you have gold in our hands. You can put the whole highend market upside down like no other person can. I said to him and many clients who heard it that people on Audiogon said that i was a liar. They laught but sais that they understand there reactions. Because you believe it untill you hear it. This is the same story about the Onkyo with my way of measurement beating the XP-20. Now I can only use words, but I can say one thing: I am a lot better in sound than in words. I can create exactly as what I say in words. Because the best and most convincing sound always will win.
