DCS Vivaldi stacks vs Esoteric Grandioso G1, D1, P1 stacks

Thanks for the invite Mike. I will have to find sometime to go visit you and have a listen to your awesome system. Those DarTZeel monoblock amps are something. I've read outstanding review of them on Stereophile. Michael Fremer of Stereophile claimed that they are the best amp he's ever heard in his setup. 
They are expensive too (around $145k). Again spectacular setup Mike.

I wished we had more hifi stores and more selections here in Puget Sound area.
I would hate to work with those dealers outside our area. It isn't very convenient for me. 

I would love love and look forward to meet you and have a listen to your system one of these days. I'd always look forward to meet another fellow audiophile like yourself. I don't really have many audiophile friends. Most of my friends are very ignorant when it comes to hifi. 

folkfreak, thanks for the info. I realized there are only couple Esoteric Grandioso dealers in the US because the Grandioso line is quite a bit more expensive than other Esoteric lines or series. I live in Seattle, WA. I might have to contact them to see if they will loan me the Grandioso G1 master clock, D1 monoblock DAC, and P1 CD/SACD transport. Actually, our DCS Vivaldi CD/SACD transport was based on the modified Esoteric Grandioso CD/SACD transport.
But I will be more intrigued with the Grandioso D1 monoblock DAC units and how it will compare against my Vivaldi stereo DAC.  We'll see. 
Or I might just stick with my DCS Vivaldi stacks. 

Caphill,

This is going to sound like sacrilege but I would keep what you got digitally. 

In reality you can get way better electronics and cabling and that is what I would recommend you look at if you are itching to make a change. 

Yes the Dgastino stuff looks fantastic and does sound good, but there are many industry insiders that are not bowled over by Dan's stuff, we have heard this same setup at shows and were not impressed, it is very good hifi but pales in comparison to some of the other reference lines of electronics currently on the market. 

If you want to hear amazing electronics listen to Gryphon or T+A, add a really fantastic non current limiting power conditioner, such as what Audio Magic makes, and look at Enklein  or Tara Labs cabling and I think you would be amazed at how much closer to real music your new system would come compared to the old. 

We did a interesting demo of a $120k Krell Master Reference Amplifier vs a T+A HV 3000 power amp and power supply $32k for the pair and they crushed the older Krells, yes those are older Krell designs and yes Dan has moved on with some faster output devices and switched mode power supplies but the design of the MRA was the best that Dan could build and in comparison spec wise was was on another planet compared to his new stuff.  In terms of many amplifiers the Krell MRA was the ultimate beast of a Pure Class A power house amplifier, with only the largest Boulder amplifiers today that are the clone of those amplifiers. We have always found the Boulders to be a little on the dry side for our tastes.

Again this is only our opinion, but until you dare to question some of your choices you might not know if you are on the right track or not.

That same client was also using Transparent Opus and the Enklein cabling was better. 

We are also not saying you shouldn't try an Esoteric stack if you are that curious, you should ,but again perhaps making some of these other changes might work even better for you. 

We would also argue just because Wilson uses brand x y or z at a show doesn't necessarily mean that is in reality the best pairing, sometimes politics is behind some of what you hear at shows.

So perhaps different electronics might be an even better thing to change or perhaps not your call,
