the smoothest sounding speaker

The various Spendors have an excellent reputation for accurate reproduction with good imaging but non-fatiguing sound.

Spendors are definitely somewhat colored but in a very musical way. They are still well made in Britain transducers and forgiving of less than optimal equipment.

spendor, harbeth, proac, neat, castle, rogers.....

1. All speakers are not flat in room.
2. Most CD players "give you ear fatigue playing CD's".
3. High resolution makes matters worse, not better

Q. What to do?
A. Alter the response curve in your room to provide smooth coherent sound at the listening position.
Q. How?
A. Use digital room correction. A used Tact a generation back (say a 2.0) can be had for a little over a thousand bucks. Get the model that accepts analog inputs (designated aaa).
cheers

smoothness and resolution are at opposite ends of a continuum.

too much smoothness obscures resolution. too much resolution eliminates smoothness.

it would seem that speaker designers may voice a speaker to provide a balance of the two.

it is difficult to recommend a speaker without listening. p[erception of smoothness and resolution is subjective.

that said, i think the aerial 10t is a good choice.
