It Happens Every Time I Calibrate

I think we all do, but I think you may want to consider two areas:

• Tthe difference in acoustics of the hall and your listening room. You may lack enough dispersion to give you that enveloping hall sensation.
• You may need a sub, along with properly high-passed mains.  So often listeners are amazed by how much the addition of a sub correctly makes everything sound better.

Trying to replicate live music is a fool's errand.

@erik_squires Thanks.  I agree a subwoofer can have a significant effect.  With my previous system, running Apogees, the subwoofer not only provided enhanced bass response, but also opened the sound stage ambient hall reproduction, improved the organic foundation of the presentation, and improved timbre.  To my ears, my current system is solid to 30Hz and is very good to excellent in staging and imaging, as well as timbre compared to other systems I auditioned during the assembly process. I also agree with you on scale.  I am limited by having to integrate the system into a living room of a modest house in the NYC suburbs.  I do have work to do with my system.  Portable acoustic panels between the speakers for critical listening will improve SQ and a better DAC (looking at a Bricasti M1S2 or M21). However, my observations focus on the sweet, liquid, flowing nature of a live performance where there is a vivid level of detail without a single grain and hint harshness.  I believe it starts with the recording engineering and continues to be exacerbated through the recording chain for some better recordings (50s, 60s Mercury, Decca, RCA; recent 2L, Proprious, Naxos, RR, etc.) capture the effect to a degree.  I believe unless there is a technology paradigm shift, we will always be behind in the reproduction of the absolute.  As stated, in a week or so I will loose my calibration and get out of my current critical listening mode and enjoy my system again focusing on the artistic performance even though I am now in audiophile system evaluation mode which I consider a fault. 

It's a tough one to chase.  I am sensitive to string harshness especially violins.  Sometimes I find a live performance a little on the polite or muted side in regards to the strings and it takes a bit of an aural adjustment.  That being said, I have tried to get my system to reproduce strings as close as I can to a live performance.

When you hear a very good live concert, and a very good system? It takes a while   For my ears to reprogram,In my case 3 days. I just have to accept the reality then, Iam ok.

@goose To my ears, it is not muted strings I hear in a live performance.  Rather, I hear crystal clarity and vivid detail. Recorded music on a good system can produce the same clarity and detail.  What I continue to try to articulate is that clarity and detail is, completely sweet and liquid and without any artifacts producing a harshness that is not natural to my ears.  This, I feel, we have become familiar with as hi-end clarity and detail rather than a problem with the state of the art of recording and playback.  Even the best multi 6-figure systems I have listened to cannot achieve this level of sweetness and liquidity. 

If one ponders both an analog and/or digital audio chain, seems to be a miracle how close to reality one can get.  But audio chains can be (preferences) built to approximate reality/live music, not replace it. Also, the quality of the recordings also play a major sonic part.  Comparison to reality often leads to disappointment, seems best to avoid and just enjoy both.

Looks like you’ve taken your current technology as far as you can. Maybe it’s time to try some Avantgarde, Voxativ, Volti, or Art Dudley’s beloved Altec speakers with a low powered (SET?) amp. Maybe even some Triangle’s with the paper cone midrange would be worth a listen.

Live concerts done well are the reference standard for sure. 

Acoustics of a concert hall is way different than any room at home.  So it's not realistic to try and replicate. 

You can measure the spl at the concert with a smartphone app and keep that for reference to see if you can match it at home.   Then you might work on replicating the soundstage you heard at your location at the concert on a smaller scale at home.  Then see what you got with some high quality recordings. 

Very wide dispersion/omni design speakers like mbl and Ohm are especially good at creating a live like soundstage in your  room at home.   At the other end of the spectrum highly directional designs, not so much.
