Clarinetmonster2,
Any high resolution speaker can sound musical that is what system matching is all about.
As per Heils and Ribbons the high tech drivers generally have more detail than other types of drivers.
it is however, the total design of a loudspeaker including, cabinet design, crossover design and implimentation which makes a speaker sound a particular way.
In terms of Arum speakers and Golden Ear, both speakers sound totally different, the Golden Ears are voiced a bit on the warm and recessed side while the Aurum tweeters are very detailed and exhibit the typical ribbon drivers strengths and weaknesses, also Arum Cantus speakers are virtually unknown in the US so it would be very hard to hear them.
Clarinetmonster you may want to look at the new Quad Z4 which are a $5k set of speakers that offer an amazing amount of performance for the money.
We just started to carry the Quad line of dynamic loudspeakers. We found out about the line after reading Stereophile and Ken Metcalf's review on the S2 which is a $1,000.00 pair of bookshelves seemed intiriguing.
The Quad line of dynamic speakers were designed by a famous British loudspeaker designer Peter Comenu who was the founder of Heybrook, and the engineering team at IAG.
The Quad S and Z series use a completely in house designed drivers. The ribbon tweeter is exceptional as it is a damped ribbon so it tends to sound a little less bright then an undamped ribbon tweeter.
We got in the S2 the $1,000.00 monitor and boy is it shockingly good. huge soundstage, completely seemless driver integration, very open, clean detailed top end and great bass for a compact monitor.
In fact we were so blown away by the starter monitor we ordered the larger floorstander, the S4 and the more expensive Z series.
Quad will also at this time be a hard brand to find as Mofi distribution just started to work with the brand to establish dealers in the US.
Right now there are a few scattered around the states.
If the more expensive Z series is as good as the English reviews say they are they will be an exceptional value for a speaker that sounds this good.
