Acoustic Zen Crescendo speaker crossover capacitors ... who makes them?


I own the MKl version of the Crescendo and see the crossover uses all Acoustic Zen branded capacitors. Most are blue in color with the smallest values bring black. Does anyone know what company makes these for AZ? I did email the builder, but no answer. Love any information the community may have on this topic.

Forgot to answer the question about what I drive them with. Well here is something I could talk about for hours. We could not have a bunch of gear in our living room so I had to search for a downsized, yet wonderful solution. I listened to many integrated amps including the Devialet. I ended up talking to Neal over at Sound Science who sold off $30,000 worth of separates for this Lyngdorf 2170. Well I decided to try one and my goodness was this piece special. It is a preamp, amp, room correction, dac all in one box. It actually sounded as good and in some ways better then my wonderful separates including the TRL Dude preamp, Luxman DA06 dac, expensive cabling, and Von Gaylord Triode Lengend monoblock tube amps.

The room correction in this Lyngdorf is amazing and the diffference maker. It is 100% digital from beginning to end with the signal going to analog just before powering the speakers. So the internal dac is really not a dac in the conventional sense.

I also have have a very highly modified Cary Rocket 88r that I also use with the Lyngdorf at times as I must always own a tube also. It is so highly modified that you would not recognize it as a Cary any longer with the expansion chassis and all I did.

Enjoying the new home and system and looking to get the very most out of these already very good speakers.

Hi Bill,

On the one hand you certainly have to admire the talent of Robert Lee using very low cost passive parts and getting such truly high quality sound. A quite talented builder with excellent design and execution of the Cresendo.


However I do see your point and agree that the wise selection and placement of high quality resistors and capacitors will yield more from this fine speaker. Those passive parts do sonically matter. No harm in making something "very" good even better with thoughtful part upgrades.

Yes Robert’s design is not in question as the speaker is awesome. The crossover is very complex with many parts. 15 resistors and 13 capacitors per speaker with many additional inductors. Easy to see why one could not use Duelund level parts!

That speaker with Duelund quality parts would retail for 35 K easily. Bill that is quite a complex crossover.
