Speaker upgrade for classical music

I ’ve been playing with a Quad S5 recently , there is a Quad 4 (5 has one more) playing on You Tube . The true ribbon tweeter is something and speaker is easy to set up.

NOT trying to say anything about it to anyone but with all the talent on
audiogon on this post I would really be grateful if anyone would say what they think . Of course You Tube is not great.

Not all Tannoys are made in China! Only the cheaply priced ones....the legacy, prestige, and higher ups are all still made in the UK at the coatsbridge factory in Scotland. They Also sound great with classical music, in fact, All music. I am never going back to another speaker, I'm hooked on that Tannoy sound. Non-fatiguing beautiful sound....

Magneplanar. Possibly in biamplification, valve high, SS bass.

Curious why you think speakers for classical differ from speakers for other genres... there’s something you are looking for that you have not said.
Anyway, for $8k you ought to be able to get some great speakers. Before i suggest anything, i’ll mention that we all have different likes and dislikes, and I think simply throwing ideas at you is a fool’s errand.
In speakers, here is a huge trade off between achieving the bottom octave+ and both cost and size. You can get superb smaller speakers at the same price as good larger ones, but missing the lowest register. You will probably care for full orchestral music. one possible solution is satellites and a subwoofer - but subwoofer placement matters if you want actual, articulated, in-phase bass.
In full-range speakers have you heard Vandersteen 2s, 3s and Quattros? great performance for the price, and the baffle designs deliver good space and imaging.
How about Elacs? Spectacular reviews at the price, and a buddy just put them in their smallish NYC apartment with excellent results, The feedback he’s given me on some masterings tells the story - he can hear and the speakers can reveal. I don know what they sell int he higher price points - these were about $1k
I hate to say it but i dont know if Spica still exists. If they do their are a wonderful speaker --- with the caveat that it demands a subwoofer. Oh, and they are a cheap, small speak that is very demanding on amp quality and performance - i doubt yours is up to the task.
I think you need to go listen.

p: maggies are a good suggestion. And overall, don't expect speakers to make the magic without the rest of the stuff being up to snuff. Weak links in chains and all that

If you are content to sit in a rather narrow sweet spot, then consider highly directional (focused) speakers combined with phase management software to widen the soundstage and separate the instruments. The goal is to minimize room effects and maximize fidelity to the original recording, while bringing out details and also creating the illusion of a wide, holographic soundstage.

Speakers (more to less expensive, all these are hybrid electrostatic except the KEFs):
Sanders 10e
JansZen Valentina (floorstanding) A8
JansZen Valentina (floorstanding)  P8
JansZen Carmelita (stand mounted), active or passive
Martin Logan (various models)
KEF LS50

Software (more to less expensive):
BAACH4Mac audiophile version
BACCH4Mac intro edition
HAF

The JansZen speakers and the Sanders are ordered direct from the companies. JansZen offers a 30 day in-home trial (I think Sanders does too). But don't do this unless you're pretty sure they seem right for you (since re-boxing and returning speakers would be rather inconvenient).

For your budget, I'd suggest the JansZen Carmelita with the BACCH4Mac intro edition (then later upgrade to the audiophile edition).  The Carmelitas are not only less expensive than the Valentinas, but also would be easier to box up and return than the larger floor-standers if you are not satisfied. If these interest you, then maybe talk to David Janszen about the Carmelitas + subwoofers versus the Valentinas without.  My thinking is that the main advantage of the Valentinas is deeper bass extension, but you can get that from the subs (which also may make main speaker placement a little more flexible). I'm not sure, though, if JansZen active models are designed to integrate with subwoofers (or software like BACCH). If not, then go for a passive version with your existing gear. JansZen is the Ohio distributor for BACCH software, so they should be very familiar with how it interoperates with their loudspeakers.
