Upgrade Spendor A4 to D7.2?

@wqgq_641 - You're welcome!

@ donquichotte - I just played Carte Blanche all the way through and it sounds great - thanks

I have the D7.2 and they might surprise you with your Rega Elex amp.  They are quite a bit more efficient than the A4.  I drove them with a tube amp for a while and they were spectacular. 

Great for piano and drums.   

Drums and bass: Vital Techtones - Drums Stop No Good. Also you could find Dead Can Dance - Yulunga (from the album Into the Labyrinth) interesting (with deep tympani, maracas etc.).

Piano other than Jarrett: a lot of options, really. For example; John O'Conor - Haydn: Sonatas, track 3 (sonata no. 47, third part) (a bit colored, but good for assessing the bass - lower treble balance, among other things). Another, better, recording I really like is Jean-Yves Thibaudet - Carte Blanche.

I found the last one on Qobuz, the others on Tidal.

Thanks Kren0006, I'll look into the Cambridge Edge or save up for a Rega Aura

If you want to really improve and stick with British gear, do the Spendor D7.2 with Cambridge Edge. I run D7 with Edge NQ and Edge W and it is fantastic, but you could do Edge A for less $ and single chassis.

I looked at Rega Elex and Spendor A2 for another system but was concerned the Rega would be powerful enough, as the A2 has low 85db sensitivity if I recall 

I'm not sure you are going to get there with the Rega but the loudspeaker upgrade is worthwhile. I would do that then add a subwoofer and see if that gets what you want.
