speaker upgrade fever

I've narrowed my search down to the JA Pulsar 2 G and a the Harbeth 3.1s Both are used priced fairly. 

I will be very interested hear your results. 

I had the Treo CT's I thought they were great 

Paired well with the 2 REL S/510's I had

I actually have KEF Reference 1 and really enjoy them but will be moving to Jean Marie Reynaud. There is a set of Grand Opera for sale locally and I'd own them right now but they are just too big for my space. They are like no other speaker I've either seen or heard. JMR has a particular sound and lushness I've just not experienced with any other brand and I've owned Audio Note, Sonus Faber, Revel & Focal. Anyway, I'm going to get the more manageable Voce Grand; mind is made up. I demoed them in Montreal last fall and although not as big a sound as the Opera, they are mighty good, Jazz & simple uncomplicated music being where they truly excel. Tax return can't come fast enough, lol. 

I am unfamiliar with the Mimas pairing, but have a pair of Vandersteen Treo CTs and they are incredibly musical.

Harbeth is a great speaker, never heard the Pulsar. Just be careful the Harbeth's IMO don't want to be pushed too hard. I heard the basket clink a couple times.

Devore makes great speakers too but get out and listen to them no substitute for that.
