Which integrated tube amp to go with which speaker

Need advice for integrated tube amp and speaker combo for a small 13'x11' listening room. I'm used to my class A low watt SET mono block system/preamp/high efficiency speakers but am selling off this system and need to change listening areas anyway.

Integrated tube amp choices are:

1. Luxman sq-38u
2. Leben CS-600
3. Ayon Spark II vs Triton III

Higher output Triton III included because I'm unsure of speaker I will use.

Speaker choices:

1. Harbeth c7es3
2. ProAc Response D2s

I listen to classical and jazz at low to moderate volumes, nothing really loudly.

Open to other suggestions.

Thank you for your help.
