brightness and clarity are two different things. brightness is emphasis on the higher frequencies, and clarity is the definition between instruments, singers, etc. When wearing sun glasses, the high frequency waves are eliminated, but (especially on the new coated lenses) definition is increased.
Is it too bright or is it high resolution?
It has been said in the forums that one mans bright sounding amp is another mans high resolution amp. Some amps and preamp combinations can deliver a high resolution presentation and to others this may be considered too bright sounding. Is there a fine line that can distinguish between the two? Personally I like very revealing & the fine details delivered but the wife says it sounds a tad bit too bright.
