The best sound I have heard was found at Jacob Heilbrunn's house.

I was finally able to go to Jacob Heilbrunn's house and hear his sound system. It was breathtaking and even surpassed the WAMM installation at Dave Wilson's house.

As the photo will show, he had some exquisite gear, most notably an Air Force Zero with Graham and SAT tonearms and DS audio optical cartridge. Preamp and amp were Dartzeel which really impressed me. There was clearly something magical in the pairing of Wilson Audio WAMMs and the Dartzeel mono blocks. They are also the prettiest amplifiers I have seen. Digital which did not sound digital was the full Vivaldi stack.

Describing this fully in words is difficult but I think of two words, lifelike and effortless. Music just flowed so smoothly and naturally. Soundstage was deep and wide. You just could not locate where the speakers were if you closed your eyes.

A truly religious experience for me. It's valuable to hear how realistic the latest reference gear can be. Spooky good in many areas!

Perhaps even better was having a few hours to talk to Jacob. He is a very interesting and intelligent person. I am very glad we have him writing for The Absolute Sound.

This was also my reaction when I listened to the dCS Vivaldi stack played through the WAMM's. How did these speakers make digital sound so real and free from the recording/playback process?

Was Jacob using the Transparent Audio cables?

What is the multi tier stack of black components to the R (as we look at it) of the AFO?

The DS Audio reference phono stage and power supply then three power supply boxes for the Air Force Zero.

Yes, Magnum Opus I believe.

It would be interested in an A/B of the Wadax against the Vivaldi in Jacob's system. The Wadax sounded very good this weekend too but the system here is far more resolving and advanced.

Yes, this would be a very interesting listening comparison. David Wilson used the Vivaldi in the WAMM development, perhaps meanwhile we can assume that the speakers are tuned for dCS! ;)

darTZeel.

The DarTZeel's were missing in his CV. He already had hosted the top VTL , D'Agostino and CH Precision in his room, time for the Dart's! I think that his regular amplifier is still the Ypsilon Hyperion.

Looking to read his review.

Dear Lee,

Thank you very much for that photo and for telling us about your visit to Jacob!

Which cartridge/tonearm combinations did you hear? Other than the DS Audio cartridge what other cartridge does Jacob have on which other tonearm?

What amplifiers is Jacob using to drive the Master Subsonics?

the Ypsilon's have moved on; residing with new owners.

Not any longer. He loves the Dartzeel now.

The PS Audio Stellar M1200 amps drive the sub towers.

The DS was on the SAT arm. I forget what cart was on the Graham. Both sounded excellent.

Interesting...any word on how he compares the Dartzeel with his outgoing Ypsilon references? I have heard the Ypsilon SET 100 Ref monos years ago, so at least I have 'some' idea of his original reference.

Did Jacob share anything about how the Dartzeel compares with his prior references? I have heard the Ypsilon SET 100 ref Monos (his outgoing reference), so I have a little idea about what he was hearing with those.

I think he likes the sweetness of the Dartzeels. I got the impression he likes them better than anything else.

I could see that. I have never heard the mighty Dartzeel 458 or 468s, but I spent several days with the 108 in a system I knew well and have spent a little time with the Ypsilon SET 100s.

I’ve known about this for awhile, but was asked not to share. Lee (Absolute Sound publisher) has mentioned it so I can comment that Jacob did move to the darTZeel.

as far as his sharing his impressions we wait for the review. He did still own the Ypsilon’s when he first got the dart’s to listen to.
