I have owned a pair of Perlisten S5t speakers for a few months. I couldn’t audition them, but I had heard the S7t at Capital Audiofest and then for an extended audition at a dealer. The S5t’s are very similar to the S7t’s, except at the very low end. I have Wilson SabrinaXs, Sabrina X’s, and Harbeth Compact 7es xdr’s in other systems.
I love the S5t. For me, the mist distinctive qualities are clarity, transparency, and extended dynamic range. It compares in overall quality to the SabrinaX. So, an excellent speaker. I would say that it has a tiny bit more sparkle and sheen at the top as compared with the SabrinaX’s. Bass extension is similar to my ears.
caveats: Different smplification. The S5t’s are paired with an NAD M33; the SabrinaX with a McIntosh MA-12000, and the Sabrina’s with a Technics SU-R1000. I have a Luxman L-509z on preorder for the S5t’s. That may make a noticeable difference,
