I'm fortunate enough to get to hear some absolutely wonderful, world class systems. My visit today to my friend and customer, Howard (The Sandman) was no exception. Howard has always had a good system, but he has always remained determined to bring it to a whole new level.

Enlisting the help of Bart Andeer of Resolution Acoustics, Howard first went to work on his room. He removed a large book shelf, fully treated all corners with Resolution Acoustics patented bass traps, installed rear diffusion and side absorption/diffusors. The Resolution Acoustics treatments are second to none. Not only does the designer hold patents, but the fit and finish makes a lot of other stuff appear "cheap". I first started using their bass traps in my room over a year ago and I can't even imagine my room now without them.

Another major change was when Howard swapped out his Pass XS150's for XS300's. We were both a little hesitant, but Howard insisted this was the right move. Was this just a "more power" play or were the XS300's REALLY and TRULY better amps? I can say, unequivocally, the Pass XS300's are better in every respect. I would venture to say, they are twice as good - and that is no small feat. The music just flows out of the XS300's with such ease. There is NO STRAIN whatsoever and the soundstage goes far beyond the speakers. The XS150's sound small by comparison. If someone is already shopping in the XS150 territory, save a little more and go for the XS300's. The XS150's are $65,000. The XS300's are $85,000. What do you get for your extra $20K? An amp that is easily twice as good.

We first listened for about an hour to the new XS300's and the room with the Resolution Acoustics. We then shut everything down and added the two Denali 2000T's I had brought with me. Each XS300 amp was plugged into it's own Denali 2000T. I would have brought the Denali 6000T, but Howard wanted to first start with the Denali's on the amps.

We sat down to listen again and immediately heard a difference. The "grunge" in the top end was gone and as a result cymbals and other high frequencies were much more natural, smoother and rich sounding and full. There was also less grain with older, more sibilant recordings. A definite improvement.

We then decided to swap out the Bryston BDP for the Aurender N10 I had brought with my Siltech Royal Signature AES/EBU. I had always told Howard I felt his BDP, although a good product, was the weak spot in his system chain. It didn't take long before the wonderful synergy of Aurender N10 + Siltech Royal Signature AES/EBU + Berkeley REF2 was shining. In my own system, I absolutely love this combination and comparing it to my R2R and Turntable, it gets really close to the real thing - analog.

We later swapped my Siltech Royal Signature AES/EBU for Howard's AES/EBU cable and we heard more detail, but also "bite" and increased sibilance.

The combination of the Resolution Acoustics room treatments and the XS300's has elevated Howard's system to a level we hadn't previously thought possible. With the room problems out of the equation, Howard's system is indeed now in rarified air.

Well done!

Mike, thank you very much for that write-up. It's rather humbling to be grouped with such industry giants as Nelson Pass (Pass Labs) & Alon Wolf (Magico Loudspeakers) and be associated with with you & Howard. We are all passionate about MUSIC and how to bring our friends, associates, & clients closer to the artist. Mike, I know you are truly gratified when you help your clients along the path and it's really the same for me. Thanks again.

I had a great listening session with Mike and George (AKA Audioseduction) today. I've been making a lot of improvements to the system and it's been a while since I had some trusted listeners over for feedback (well, Bart (AKA drb968) was there the other day tweaking in the room treatments but he didn't really stay long enough for a good listen).

I have to agree with Mike that the XS300's are twice as good as the XS150's. They're a huge upgrade - easily bigger than the jump from the Magico S5 to S7's or from the Berkeley Reference DAC to the Reference DAC Series 2 for example. And those weren't subtle improvements themselves.

The Magico S7's are everything I'd hoped they'd be and more - no, they're not M3's but for me M3's would be too small. They somehow manage to disappear even as they throw an immense soundstage and handle all that Class A power from the Pass Labs monoblocks. I did play a few things pretty loud for Mike and George - the intro to Great White's "Rock Me" (Live version), Track 1 of the Sheffield Drum CD, and Bela Fleck's "Flight of the Cosmic Hippo"... I think they were impressed! That was in addition to the usual audiophile assortment of jazz, male and female vocalists, but also stuff like Led Zeppelin's "Stairway to Heaven"... My system needs to be able to play everything depending on my mood!

The Denali power conditioners were a definite improvement over my current set-up (amps plugged directly into the wall, each on their own 20 amp circuit). My initial impression is that the improvement comes without any downside - always a good thing.

The Aurender clearly was an improvement over my current Bryston BDP-2. The Siltech digital cable made it sound even more analog (smoother and less sibilant) at the cost of some dynamics and microdetail.

Last but not least - a million thanks to Bart for setting up the room which was in dire need of his expertise. I waited a long time before doing the room - I knew how much it was needed but I didn't know how to do it properly and I didn't want to get it wrong. I'm so glad I waited! I couldn't be happier with the results! I wondered at first about the name Bart gave his treatments - the Time and Space series. I figured it was just some marketing hype or something. But once you hear the results you realize that he is actually controlling time and space. The results are awesome!
 
Howard, Thank you! It was a pleasure. I'm sincerely grateful you gave me the chance, and I love the fabric color and wood you chose. Next time you will probably need some dynamite to blast me out! What was that one track you played when we first fired up the system with the drums on the left side where we could tell the position of each drum in the kit? That was a very well recorded track.

Best,

Bart

Hi Howard,

Thanks for your report and congratulations on a truly world-class system! I've auditioned the Magico S7 and they are certainly a worthy counterpart to the Pass Labs XS-300 monoblocks.

Enjoy,
Ken
 
Thanks for posting this thread Mike. Super nice system! :thumbsup:. Those Resolutions Acoustics treatments look the business, and equally important come backed with personalized service to design and fit the treatments from their team. Duly noted!
 
Pass Labs posted pictures on Facebook. I'm like, wow, I know who that Mike is their talking about, LOL. I'd love to be able to hear Howard's system. Sounds like he has decent taste in music too :)
 
Re: Resolution Acoustics, Pass XS300's, AND Shunyata Denali make Magico S7's shine

We first listened for about an hour to the new XS300's and the room with the Resolution Acoustics. We then shut everything down and added the two Denali 2000T's I had brought with me. Each XS300 amp was plugged into it's own Denali 2000T. I would have brought the Denali 6000T, but Howard wanted to first start with the Denali's on the amps.

We sat down to listen again and immediately heard a difference. The "grunge" in the top end was gone and as a result cymbals and other high frequencies were much more natural, smoother and rich sounding and full. There was also less grain with older, more sibilant recordings. A definite improvement.

Based on what we heard with the Denali 2000T's in the system I ordered a pair. When Mike brought his over for the audition, he used a pair of Sigma Analog power cords and we heard what he described above - grunge removed, less grain, and a smoother, richer, more natural sound. For my 2000T's, I went with the Sigma HC (High Current) power cords to better match the XS300 amps. I expected to hear the same level of improvement I'd heard when Mike was over, after days or weeks of break-in time.

I added the Denalis to the system and powered up the system. For the first hour or so it sounded okay, maybe a bit cleaner but otherwise not much different.... except that I had to turn up the volume a fair bit (2 or 3 dB) to match my usual listening levels. I left it playing some jazz and came back an hour later.

Wow! That was quick - only an hour later and I'm not only hearing all the improvement I heard with Mike - it's *much* better than that. Dynamics and bass are off the charts, background seems even quieter, and the overall presentation is more natural (organic if you prefer). I can listen at my previous levels but somehow the system wants me to keep it at the higher levels. I can't imagine how it's gonna sound when it's really broken in.

So two questions for the Shunyata enlightened -
Am I imagining things or does the HC cable make that big a difference over the Analog?
I'm gonna do some testing, but theoretically - should I leave the Flux-50's on the amps or remove them now that I'm using the 2000T's?

Okay... off for some serious listening (and thinking about getting the Aurender next :)).

Your massive XS300's can really benefit from the Sigma HC's. Therefore, I would suggest two HC power cords for the big bad ass XS300's into the 2000T's. I would suggest a 6000T for the preamp/sources and a sigma analog from the 6000T to the wall. I can bring my 6000T up for you to hear so we can be sure. As for the Flux-50's, that's a question for Caelin. But if you like what you're hearing...

The Aurender is a no brainer. The Aurender N10 + Siltech Royal Sig AES/EBU + Berk REF 2 is the closest digital comes to my Studer R2R (the benchmark). Scary close. It's truly the synergy of all three pieces. Remove one piece and you take away 50% of the effect. It's like 1+1+1=10.
 
1+1+1=10?
:D
I know exactly what Mike means though, maybe it's that 'new math'! ;) Sometimes a specific combination of components allows the sum of their performance to far exceed what you would expect from each on their own merits. When you find such a combo it's rare and can provide truly exceptional value. We can all benefit from Mike's (as well as other forum members') personal experience in such matters, just another benefit this forum provides!

I get it!! It was a joke! ;)
 
Kev -I was waiting for you to say "1+1+1 = 10"? Mike, you must have been home schooled. [emoji6]

Re: Resolution Acoustics, Pass XS300's, AND Shunyata Denali make Magico S7's shine

Mike,

Have you ever tried the Zitron Anaconda AES and or AQ Wild AES? These are very highly regarded. I believe the AQ is Robert Harley's reference. I don't own a Berkeley Reference but, I have a feeling this product with MQA playing back an MQA file. It's all about time domain resolution and lack of distortion. Once this is achieved in digital the gap between the two has closed. Again my opinion and subject to personal subjective preference :-)

I haven't tried those AES cables. I would love to try the AQ. I have a full AQ Wild loom on my Vandy/Ayre system now (just loaners from my rep) and wow wow wow!

Bingo! I also want to hear the Siltech Royal Sig. vs. the Audioquest Wild AES/EBU. I have the Audioquest Wild Blue Yonder analog interconnects and they are phenomenal. Tremendous detail and nuance but neutral without a hint of brightness. I've never heard the Siltech AES/EBU but I'm really curious if it will be as neutral as the Audioquest.

Best,
Ken
