Absolute top tier DAC for standard res Redbook CD

hi paul, Joseph are very fine speakers... Heard them several times.... Last driven by the Rowland M825, and the result was exceptionally involving.

please explain... "problem with outside their passband"

Regards, G.

Guido, I think he's saying that the "infinite slope" crossovers prevent the metal cones from being exposed to frequencies they can't handle without breakup and/or ringing. While a more conventional lower order crossover would provide a much lesser degree of filtering of frequencies that are outside of the range the drivers can handle in an optimal manner.

I have no specific knowledge of Joseph speakers, but that is how I would interpret the statement.

Best regards,

Al is correct as usual! While Joseph Audio speakers do not actually use the original 'infinite slope' crossover design that they use to, they still incorporate a very steep slope crossover filter design which sounds even better. As such the crossover prevents frequencies in the breakup regions of the drivers from being excited. So they benefit from the speed and articulation of the drivers used while avoiding their potential shortcomings. The Pearls are a true full range design that have a seamless presentation with superb imaging. Most people are shocked at how good they are when they first hear them.

Thank you Al and Bill for the technical explanation... When I heard Joseph speakers at RMAF 2013, they definitely pleased me without reservations.... I enjoyed the suite so much that I returned to it a few timesfor more good music ... Which is not a particularly common outcome for me *grins!*

Hi all. First off, I have the Bricasti M1 in the house and have been listening for a few days. I am holding opinions for a bit so I can provide a solid report.

I want to thank all for getting into my speaker search. I'm sorry I sidetracked the thread but its been a fun sidetrack and you guys have given me great suggestions! I promise this thread will end up back on the DAC track when the speaker decision has been finalized.

Here is a list of my current possibilities, almost all of which I have not heard. Obviously the Marten Coltrane Tenor is currently my front runner. But since it is a whopping $80K retail I am hoping to find a slightly (or significantly) less expensive option to consider; although if the Tenor ends up being the one that just does it for me then the Tenor it will be. I will not list the speakers I have already removed from my list…

Marten Coltrane Tenor (or even the Coltrane 3 if the opportunity arises)
Avalon Time or Isis
Joseph Audio Pearl 3 (I just put this on the list at your suggestion but I need to confirm it is not rear ported)
Perfect8 - The Point (I know I love these but they are a super whopping $100K)
Soulsonic - Holograph (Intriguing but very eclectic and VERY expensive)
Alkemia Vero - Italian omnidirectional (also intriguing but very expensive and eclectic)
Vandy 7 - Admittedly has not done it for me when I have heard them before. But at your insistence I am giving them their full chance to catch my heart.
Avantgarde - Duo Grosso (I know, a horn in a small room. But I have spoken to many people who think they would fit perfectly in my room and I have always enjoyed the way they sound; albeit a bit romantic. I'm also not in love with the fact that they are powered subs and that I would probably benefit from a tubed amp instead of my uber solid state amp that I love so much). But its on the list
Trenner & Friedl - Isis (A solid choice but hard to find. I'm doing my best to get my ears on a pair)
BMC - Arcadia (Also a solid choice but not easy to get my ears on a pair. I'm trying though)
Nola - Baby Grand Reference Gold (I need to confirm, but i recently realized that these are not rear ported and are certainly worth consideration if they work for my room)
Ascendo - Heard them recently and they are very good. low on my list but thinking about them….
Salk - Soundscape 10 (a solidly designed speaker for a reasonable price. I need to hear them to see how good they are. I am having a hard time believing that the Salk or the Vapor Joule would really compete with some of the much more expensive speakers I am considering)
Vapor Audio - Joule black or white (I'm thinking white) - A few threads really threw a monkey wrench into their public opinion but I'm not sure what to believe. They use similar drivers and design to the Salk and my same concern exists. I'm trying to hear a pair.
YG - I have heard them several times and although they have many strengths, I don't think they are for me.

I think thats it right now, although I may have forgotten one. I know Wisnon keeps suggesting the Heil speaker and I will try to hear a pair. But I don't think it will compare with some of the better speakers I am considering, especially in the low frequency extension which is really important to me.
