Short answer: the JBL HDI-3600. Both are rated 4.3/5 for sound quality (#63 and #79 of 226 floorstanding speakers), and the JBL HDI-3600 costs $3,800 against $6,990 for the Perlisten A4t, and with sound quality even, the cheaper one is the better buy.
Why pick the JBL HDI-3600: CEA2034 spinorama shows a fairly even on-axis response and flat overall frequency response, with high 90dB sensitivity and very low distortion through the midrange. Watch for: A wide shelving-down above 2kHz affects the in-room response, and vertical dispersion is a bigger issue than horizontal: the reviewer noted the dip is wider here than on the smaller JBL HDI-1600, making it more audible.
The Perlisten A4t is the deeper-bass pick. A larger A series tower with three 215mm carbon woofers. Its bass reaches about 28Hz before falling 10dB, against 62Hz for the JBL HDI-3600. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Buy the JBL HDI-3600. Both are rated the same for sound quality, and it costs $3,190 less than the Perlisten A4t.
About the ratings: the Perlisten A4t’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 4.0 to 4.6, so this verdict could change once it is measured.

JBL HDI-3600: $3800 per pair Audio Advice eBay
Same family: the JBL HDI-1600 (bookshelf, rated 4.2/5), the JBL HDI-3800 (larger floorstanding, ranked higher, rated 4.5/5), the JBL HDI-4500 (center, rated 3.7/5) and the JBL HDI-1200P (subwoofer, rated 3.9/5).
Pros: CEA2034 spinorama shows a fairly even on-axis response and flat overall frequency response, with high 90dB sensitivity and very low distortion through the midrange. Triple 6.5” Advanced Aluminum Matrix woofers and a 1” compression driver in JBL’s HDI waveguide. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 89.5dB.
Cons: A wide shelving-down above 2kHz affects the in-room response, and vertical dispersion is a bigger issue than horizontal: the reviewer noted the dip is wider here than on the smaller JBL HDI-1600, making it more audible. Narrow vertical sweet spot means careful listener-height positioning matters more than usual.
