The voicings
Take the close voicing and drop its second-highest voice an octave. The most-used four-note voicing on guitar and in piano left hands. Strings D-G-B-e, frets 2-2-2-4.
Drop the third-highest voice of the close voicing an octave: a wide, open sound. Strings A-G-B-e, frets 4-2-5-4 (position 1).
Root, seventh and third only. The fifth is dropped — it adds nothing to the chord's identity — leaving a light, clear voicing. Strings E-D-G, frets 5-6-6 (position 2).
Bill Evans-style left-hand voicing: the third on the bottom, the ninth on top, the bass player supplies the root. Strings E-A-B-e, frets 9-7-9-7 (position 5).
The companion rootless voicing with the seventh on the bottom. Alternate A and B so the top voice moves by step through a ii–V–I. Strings E-A-G-B, frets 4-2-6-5 (position 2).

Common questions
A, C♯, E, G♯ — chord tones 1 3 5 7. Rootless voicings add the 9th, B, and leave the root to the bass.
The shell voicing (root, seventh, third) on strings E, D, G: three notes, one comfortable shape, and it still sounds unmistakably like A△7.
Start from the close voicing A C♯ E G♯ and drop the second note from the top an octave: E – A – C♯ – G♯. It spreads the chord so it fits the hand — and on guitar it fits four adjacent strings.
A△7 is the tonic Imaj7 of a major key, and any maj7 chord. Its character is bright, settled, at rest.
