Help me choose: Harbeth 30.2 or SHL5+ XD in a 10 x 13 feet room?

Hello everyone, 

Need some guidance on speaker selection. I am primarily targeting Harbeth. Open to others’ opinions. For this discussion appreciate experienced feedback on these two speakers. Sharing my room and audio setup details below.

Room:

Dimensions: 9.7 ft (W) × 12.5 ft (L)

Ceiling: Cathedral, 9.6 ft peak

Floor: Pergo Laminated, 5.5 x 9 ft rug in center only

Speakers: Tontrager Stand on bare floor, not rug

Front wall: LG G5 77" TV + Nakamichi Dragon Sounbar. Butcher Block Acoustics stands and rack. 

Rear wall: Window behind MLP, curtained. 

Listening distance: ~5 - 7 ft

 

My Audio SYSTEM:

Main speakers - to be determined. Need your opinion.

Amp: Synthesis A100 Titan (KT66, 100 W @ 6Ω)

DAC: Holo May KTE

Streamer: HiFi Rose RS130

Subwoofer: REL S/510 (planned)

Cables: Audio Note Lexus 96, DH Labs Air Matrix Cryo, Mirage USB

 

Taste in Music: Vocals, acoustic jazz, classical, opera, Tool/Dream Theater

 

Given the room volume is small,  does it make sense to go with M30.2 or M30.3 and pair it with REL S/510, or SHL5PLUS XD or XD2? Which speakers will be optimal for best outcomes? 90% of the time I listen to vocals, jazz, and Acoustics. 

Thanks in advance for your guidance.
