Which speakers did you find bright, fatiguing or just disappointing in some way?

In my home:

Focal (demo), Klipsch Palladium (owned), B+W Diamond Series (demo)

In someone else's home:

Tekton with the Be upgrade, Wilson with the Focal tweeters (no shocker, however I DO like the Wilsons with the new Soft Dome tweeter)

Demoed in multiple stores:

Paradigm Persona, the entire line-up.  The ONLY time I thought they sounded good was a pair of the 7's with McIntosh Electronics, using Vinyl as the source.

B&W 703s with Rotel front end. My first system. Upper mids shredded my ears and they had to be cranked to open the mids up.
Sadly I feel the current models have the same issue.

To many to mention.

Green Mount Audio Europa. Bright and fatiguing describes the perfectly.

@bdgregory I consider your claim to be dubious, and if accurate, almost certainly related to your associated equipment.

I had the Europas, followed by the Callisto, and while the latter was certainly a step forward, I would never have characterized the former as "bright and fatiguing". I was using a Jeff Rowland Concentra integrated amp, and Electrocompaniet EMC-1up CD player.

There is a very detailed review of the Europas here on Audiogon, entitled "Review: Green Mountain Audio Europa Monitor". That user's experience is far more in line with most, I would say.

There are many more opinions on a thread entitled "A few questions for Green Mountain Europa owners", and the words "harsh" and "bright" are never used to describe the sound.
