Another system matching request but I will be as concise as possible. Have used a Keces E40 and a Hegel h160 for a long while with mostly the Keces as main driver. The Keces is fairly transparent, slightly warmer than neutral and fairly resolving while remaining smooth. The h160 ups the capabilities with a bit more detail and weight to notes particularly piano. At the SPLs I listen at and on bookshelf/standmount speakers both do well and I refer to the E40 as my little Hegel.  Speakers used were Focal 807W, Triangle Zetas and Dali Opticon 1s.  The most noticeable difference in sound comes from the Opticon 1s where the Hegel adds weight to notes on piano as the most distinguished difference but also some glare in the upper mids in movie soundtracks, perhaps as to how its processed. On the Focal, they essentially sound similar more similar.

I recently picked up a Van Alstine CA-1 and what it seems to add is more transparency, at least as good if not more-so across much of the spectrum than even the Hegel.  The CA-1 is still considered smooth but not as smooth as the other two amps possibly from perceived less warmth in the upper lows and lower mids as its fast and seems more texured.  Also, the CA-1 trades back and forth with the Hegel on microdetails, instrument texture in some cases better.  Separation is at least on par if not better. There's less glare in the upper mids vs the Hegel as these speakers seem to accentuate that.  All in all I find I like the CA-1 for its transparency, imaging and quickness particulary the low end and its easily a greater improvement to the E40 in the areas I want. It doesn't give more than what's called for in bass. I wouldn't call it thin but not as full/juicy? as the other two.  Also seems to have a bit more depth in the stage, definitely nice imaging.

So, now I want to upgrade my speakers in something a step up from the 807Ws but in a smaller package that provides transparency and shows instrument textures while keeping a natural tone, imaging, separation and stage depth while sounding like music and not sterile.  Also should be exciting enough without assaulting my senses aka MA Silver 100. 

Interestingly, the CA-1 really brings alot of life to the budget Triangles, a bit more so than the Hegel even.  So, selling the 807W, maybe the Dali but keeping the Zetas as they sound so good in a smaller package for the time being.

Speakers do not have to be the most resolving or refined in the upper registers.  I found Dali Menuet SEs, Dynaudio Emit 10 sounding too smoothed over as examples.  But a real foot tapper that makes music sound real, engaging, as real as it can in a room at moderate to low SPLs. It must convey music at lower SPLs too. I do not listen at loud levels anymore...we all grow older.

So I figure up to double the price of the amp is the limit or about $3K and able to play nice with a low powered 55/85 watt at 8/4 ohm CA-1.  Looking to downsize and the CA-1 is a manageable weight and simple enough for my needs.  Smaller speakers with a smallr driver desired but looking for those that give me the attributes mentioned (natural transparency and tone, instrument textures, imaging, separation and stage depth, in essence, capturing the space/ambiance of the venue)

I am pairing the VA CA-1 with a Topping D70s dac (smooth for a Topping) and possible candidates are:

Fritz speakers

Totem Bison (size is nice)

Cabasse Murano

Revival Audio Atalante 3

Any other speakers you could suggest  or explain why the above mentioned may not be suitable with a 55 watt amp would be appreciated.  I considered the Closer OGY as well but I listen to symphonic music and it might have issues with that, such as the little Dali. The Triangles handle even large scale well and its a 5.25in. mid driver although they lack in note weight and can be a bit sibilant.  Voices, natural tone and textures of piano, horns, strings important.  Typically I like paper or some variant of it over Alum. or Kevlar mid cones.  Used to metal domes but soft is good too if it can render the above instruments.

Going to class D hundreds of watts for hard to drive speakers is not desired at this time either, hence my constraints. So if a speaker can only perform with high current or louder levels, it isn't considered.  Thanks for any input.
