2wq filters: what do you recommend?

Harry,

If you have a multi meter, many of them have a setting for measuring capacitance.

You will have to add values to get as close to the "ideal" value of .03975uf, which @50K=80Hz. .039uf is 81.54Hz @ 50K.

I like the DynamiCap best of what I have tried so far, which has been the AuriCap(which everyone loves but I find somewhat dry and subtractive sounding but KILL the crap in the X-2! AuriCaps do come in some odd small values from Pearcy but not from Parts Connexion) and also the InfiniCap which has been replaced by the DynamiCap.

Teflon caps like the RelCap TFT Exotica or Chris VenHaus's V Cap

are said to be wonderful but the cost is way out there! You would need a total of eight .01uf caps for a total of $223.92 even at the 5-24 peice discount rate! I would love to try them, but. I would also like to try the Cardas caps.

DynamiCaps are very fragile! Do not get them too hot when soldering. You can take advantage of the fact that the .01uf is really more like a .013uf(I have confirmed this and Michael Percy lists them on his site as .013's)and add three together for each side to get as close to a .04uf value as you can with the likelyhood of them being fractions over .039 when three are added up(get them matched and tell them that they are for a filter when you buy them so they understand that the value is critical, you don't want to be 20% off like the X-2 can be, that's why I suggest you find out what they really measure at.) They don't have to look pretty if you can't do that they just have to sound good and not short out. You need to reinforce them if you have real heavy IC's that will pull on them.

harry,

in case you're wondering where maxgain is is getting the capacitance values from, the formula is 1/(6.26 x crossover frequency x input impedence) in your case 1/(6.26x80x50,000).

maxgain,

thanks for the input. what have you heard about the model 5 filters. i see a pair listed here now. do you know how they're hooked up. i have no idea what they look like. if they have to be hardwired, i don't think i want to mess up my ic's.

Keith,

I have listened to the 5 filters with a pair of 5a's and some other very nice stuff. The system was amazing. I can't say much else about it without hearing it in my system. The filter is said to be the most transparent high pass for the Vandersteens. The nice thing about them is that they are switchable for impedence. Unless your system is pretty stable as far as keeping the same components for a long while like I do the versatility of being able to change the cap value with a switch is handy.

I have a photo of them. I can e-mail it to you if you like. They have rca or bal inputs on them just like pluggin into your amp and a fixed pigtail of some sort of top of the line AudioQuset IC that goes into the amp.

maxgain,

thanks again. so they hook to the amp the same as the x-2, with 1 set of interconnects? i would appreciate you e-mailing me a photo if it's not too much trouble. my email is kitosanx@hotmail.com going to call my dealer to seek for further input. upon doing another search here it seems like this is the way to go as bigtee and several others have commented that the 5 xover is very good.

Keith,
I sent you an e-mail with two attachments.

If you have the cash handy buy the used ones NOW. You can't go wrong. You can always get your money out of them and they don't show up often.

If you have read much of what Bigtee or I have written on the topic you know that this filter is critical to the sound of your system. Everything passes through it! The X-2 as I said before sucks for any system that you desire the ultimate in clarity or resolution. They might be ok with an inexpensive home theater set up.
