most clear, crisp sound power amps, monoblocks ?

Pass Xs 300's should fit the bill,but you should pair it up with the Pass Xs Preamp to get the full benefit!

It depends how much money you can spend. But money does not garantee you a good live sound. In almost 16 years of time I also encouterd many highend sets with a poor endresult.

The combination of the right tools togheter ( sources, speakers, amp, pre amp, cables, conditioner etc) can create a live and realistic sound.

Acoustics of a room are the biggest enemy of a set.

When you have a system with a bigger freq. response, you can create a more live like sound. It is all about making the perfect combination of tools. I call it the art of sound.

I wrote a personal view in how I see a blueprint of the absolute sound. I call it Total sound.

In my personal opinion Pass Labs also make the most complete sounding poweramps.

sony walkman cassete players with avls playing recorded metal tapes or chrome type II tapes :D it is no joke:)p

The range of answers here is awe-inspiring. Condescension to curmudgeon; elitist to judgmental. And even a few well-meaning answers thrown in. Bojack had it right - lighten up, audiogoners. This is a hobby forum, not a philosophical statement of identity.

Seriously, if the OP were my first post, these answers would only serve to edify the misconception of hi-end audio as the domain of the self-absorbed and out-of-touch.

Having said that, I do agree that the question is much too vague to give any legitimate empirical answer. But Mitch4t and a few others already suggested a good way of saying it without reverting to trolldom.

When I come across a vague question and I think I can help, I do. If not, I move usually just move on.
