Speaker upgrade for classical music

I can echo Magnepans, perhaps 2.7qr's or 1.7i's in front, an MMG center channel, and two wall-mounted surround maggies.  Buy used and your'll have plenty of change left over, and no need to ever upgrade speakers again.

I was looking at these a while back, https://www.aperionaudio.com/products/verus-iii-grand-tower-speaker
Aperion Grand Verus III, reviews are good and you get a free 60 day listening tryout. Nothing to lose there! Enjoy your search, from the description of your gear, you need to upgrade your main speakers.

I listen pretty much only to so called classical’ music from all times periods and genre and can as many have here recommend electrostatic and planners speakers for such music.
However after having owned Harbeths for 10+ years (M30s and then M40.1s) which were fantastic (as most ’BBC inspired’ speakers tend to be for ’natural’ sound). I will throw another make model into the mix that doesn’t get mentioned much but is also a matured classic still being manufactured today.
Which is the Finnish made Gradient ’Revolution’. which is easily within your budget new or used.
I went from the Harbeth M40.1s to active Revolutions around 6 years ago and have had no desire to change speakers since.

Hello from NZ.  My main listening is classical - Earliest is Buxtehude and latest is Pärt.  Piano to Orchestral.  My current speakers are Magico.  They are nice and do classical just fine.  I do not particularly recommend them but to get what you want I think the following need to be taken into account.  First, you can improve your room.  Judicious use of damping materials and experimentation of speaker placement can in effect largen your room.  Second, there is no substitution for cubic inches.  Yes small speaker manufacturers will claim otherwise - but it is difficult to work against the laws of physics.  Third, do not get ported speakers (possibly a type known as Transmission Line).  Once you lose the woolliness of the port you will benefit from a clear and more accurate sound.  This is not without cost as sealed designs tend to require more amplification.
Finally I endorse upgrading the amplification.  I think the amplification and speakers should really be regarded as a unit.  In fact some manufacturers (eg ATC) do exactly that with the 'active' speakers.

I have been following this post very closely.  There are some great ideas.  So here are my thoughts for what it is worth.  Since you already have floor standing speakers for your front speakers, I would be looking at Vienna Accustics Beethovens.  I had a pair of these in the past and loved them.  Very articulate, and detailed.  Smooth high frequency, balanced midrange, and perfect bass. Very much like you would experience in a concert hall.

I also agree that Magnepans are an excellent choice.  Very detailed as well. Great for classical music.  They also require a powerful amplifier due to the fact that they are electrostats.  Maggies tend to have a sweet spot.  You have to do a lot of speaker placements to find the ideal spot.  Once you find that spot you will fall in love with the sound.

If you are thinking of bookshelf speakers, I recommend the Bowers and Wilkins  805 D3.  I currently own a pair of these speakers.  Great  articulation and detail a little lite on the bass, which can be enhanced by a subwoofer.  It is very important that you have good quality cables throughout your system.  Pays off in spades. By the way the B&W speakers run $6,000 a pair.  A little pricey, but worth every penny. 

Harbeths are another good choice for a bookshelf style speaker.  Great sound.  They do look a little rustic, but sound fantastic.  Highly recommended.   Good luck on your search for your next speakers.
