which excels at Rock and Roll

@robshaw - That CODA is supposed to be a real work, and I love the way it looks. I never even heard of CODA until I recently started going through these threads for preamp suggestions. But then I'd never heard of Aric, either, and now I have one of his wonderful preamps from this extremely personable fellow!

When auditioning speakers, I went to my hi-fi shop and listened to Dynaudio Heritage Specials, YG Tor, and Parker Oscars. I liked them all but preferred the Martens the best. Then I started thinking if I get the Oscars, I'll forever be drooling after those Parkers, even the ceramic tweeter ones (I've got those), so they gave me a comparison between Oscar and Parker. Heard the fat, detailed midrange on those considerably larger Parkers and said "I'll have those.". I'd love to give you other recommendations, but I haven't heard any other speakers in decades. 

Enjoy yer Metallica - 'Pastor of Muppets' was always my fave. And here's an amusing tidbit - a friend of mine out here in California knew them in the formative days and is the one who came up with 'Metallica' when they were looking for a band name. 

WOW!!!!! That is saying something.  I laughed MAO when you said about the drooling part,  Oscar/Parker thing!  I said he's just like me, The poor Man!!! Thanks for all the input, much appreciated.  If you know of any places that happen to have some for sale, Oscar or Parker,  used, keep me in mind. In the mean time I will still be researching the others that I mentioned, Thanks again for taking the time.

Bose speakers is the best for any type of music, Also SVS and Tekton is amazing 

Just one example: If you want to play AC/DC or The Ramones at 100dB, the QUAD ESL is a bad choice; a pair of them is not going to last very long if you do.

Classical music can easily be at 100dB! What you are talking about here is that Quad ESLs (like the 57 or 63) really aren't suited to play at really loud volumes. 

If you want to do that you need something more efficient. Its not that the Quads otherwise will misrepresent the Ramones. My Classic Audio Loudspeaker T3s can easily play Romones or Verdi's Requiem at 100 dB. 

Next thing you know,..he might claim his 'genre agnostic' tube amps might just work great for every kind of speaker I have and my entire music collection spanning every genre available.

@deep_333 Nope- not gonna do that! If you have the right speaker, they will play any genre equally well though.

Any designer can tell you its impossible for a speaker or amp to favor a certain genre for a very simple reason: musicians, regardless of what kind of music they play, have ears that use the same hearing perceptual rules. So they tend to make music with similar balance, for example bass notes will always tend to consume more amplifier power and thus need greater excursion on the cone of the loudspeaker.

Like I said, for any recording you can come up with that seems to reinforce the myth, there's one out there that will disprove it. This is simply because the idea that speakers can favor a musical genre is a logical fallacy based on a limited sample size. 

In my experience some maybe even most speakers are absolutely suited more for certain types of music. So I totally disagree based on my experience with probably 30-40 sets of speakers.
