Bookshelf/subwoofer combo

I have the KEF Reference 1 Metas with a pair of subs. Worth a listen. 

Any power sound audio sub that tickles your fancy.

I haven't heard Studio Electric speakers but they receive many laudations.

Sold direct to consumer ... I believe, with a 30-day trial period.

Give them a look!!

Suggestions:

Actives: Buchardt A500, ATC SCM20ASL, Dutch&Dutch 8c  (would be over budget but no need for streamer/DAC/amp or sub, for that matter, and has room correction.) Genelec 8351

Passives: Studio Electric M4, Alta Alyssa, ProAc Response D2, Amphion Argon 3s

FWIW, I have a pair of Studio Electric M4s, they are excellent speakers.

I love my Studio Electric M4.   Such a great speaker.    I use them with a 10" REL in my second system.    

I have a pair of Forte IV in my main system but find myself listening to the M4 about 75% of the time.    

They are voiced perfectly for my tastes.   My brother and Dad are both Sonus Faber owners and have said numerous times how good they sound.   Strong value.
