Good matching speakers for YBA Integre DT

I am constructing a new audio system here in US.

I already bought a YBA Integre DT integrated amp and Arcam CD23T cd player. Now I am looking for good matching speakers.

I know both Integre and CD23 have clean and clear sound and they sound somewhat lean. So I hope for speakers having warm, soft, and rich sound with some body and texture. Because Integre has 50 watts only so speakers with high efficiency would be better.

I mostly hear classical music, vocals, and some soft jazz. What is good matching speakers (used) at below $2000 for me? I am considering Proac 1SC and Reference 3A MM De Capo (i). But I'd like to know what are good tall-boy speakers for me because bookshelf speakers usually need good stands.

Hope for your valuable suggestions. Thank you.
