Bloom air around instruments

Lowering the noise floor by having clean power through the mains will reveal air and ambience on the recording. Also vibration control on components and rack, and an acoustically treated room will reveal air and more in the recordings.

How do you get air around instruments

Do you mean get the speakers to disappear?

Get better speakers. Most speakers have horrendous time coherence.

As a former recording engineer, I can tell you that there is no 'air' in the studio. In good rooms like Paramount, Sky Walker, Hit Factory, Oceanway, Capital A, etc. an acoustic guitar or piano sound much as it does in a small club.

Varies by system and recording. 

A quiet room.

Great room acoustics.

A very good DAC.

Great answer by @folkfreak regarding setup of a system.
And air can only be heard if it's in the recording.
@ieales provides good comments about studio recording. The "air" and sense of space is artificially created by the engineer. But in a venue such as a church or the Musikverein concert hall there is natural reverb. But the end result of "air" and space on the recording is created by natural and artificial reverb, and only with proper mic'ing of acoustic instruments.
