เห็นรูปคุณkeang แกะ C Metal film แล้วได้ idea
กะลังว่าจะไปซื้อ Copper shielding tape มาพันรอบหม้อแปลง กับอื่นๆ
แต่แพงอยู่ ม้วนละหลายร้อย เดี๋ยวไปแกะ C metal film มาลองดีกว่า ทำขาหัก/กุด เก็บทิ้งๆไว้อยู่หลายตัว
croft, I am suprised that you find so much difference between the Kimber caps and the AuriCap. They are the same damn cap other than the leads. Do you remember the older SidrealKaps? That was also the very same cap as the AuriCap, but with Kimber teflon coated stranded copper leads instead of the solid leads found on the Auric units. I assume that Kimber and Sidreal are one and the same. I am sure that the leads do sound different.
I don't see all the fuss over AuriCaps myself. They are good. Perhaps a bit better than a Solen, but nothing to get all worked up over. The AuricCap subtracts harmonic richness and ambient decay info from the signal. They sound a bit dry. They just don't let the signal pass unaltered as well as some other caps I have tried. I don't know anything about the Sonic Cap. I haven't listened to them.

I was in on the design of the SiderealKap and the Auricap. I can most assuredly promise that Auricap and KimberKap are not the same. To assert that the only difference is the leads, is a huge and erroneous assumption.
John, I am always happy to admidt when I am wrong. I got that information from someone in the business of selling caps. Sorry to be spreading disinformation. It is my understanding that many of the high quality cap brands available today are manufactured by one company in Califorina, so it didn't seem all that unusual to me for this to be the case. I had used the SiderealKap as my cap of choice back in the eighties. SiderealKap, as you know, had leads that appeared to be Kimber teflon coated stranded copper. At some point the SiderealKap seemed to disapear from the the U.S.market and it was a short time after that I started seeing the KimberKap being sold. I suspected at the time that it was a re-branded SiderealKap as the apperance was so similar and seemed to both use Kimber leads. As I said, I was told that the KimberKap, AuricCap and the SiderealKap were one and the same by someone in the business. Is my information also incorrect that the AuricCap and the SidrealKap are identical save for the lead material? I am not trying to get at anything negative about the AuricCap by asking this. As I said, I was a fan of the SiderealKap when it was more available a number of years ago. I still have 3, .01uF SiderealKaps in my parts box. If not, e-mail me directly and I can help you clear this confusion up with one of your vendors, who has this clearly stated on their web site.

No worries on your intentions. The fact is that you have been misinformed. However you do have some of the pieces correct. Here'z the scoop. Sidereal Akustic Audio Systems, Inc. in the early 80s developed SidrealKaps which incorporated Kimber's wire for the leads. When SAAS went down, Ray Kimber picked up the ball as best he could and continued making a "simular" cap made by the same manufacturer. Simular, but not quite the same per the non disclosure agreement SAAS had with the manufacturer. In '98 Audience was formed by the same principles that started SAAS, Richard Smith and myself. Audience developed Auricaps incorporating what we had learned with SiderealKaps and several new design techniques. Therefore, all three brands are different, as noted by the distinct difference in performance of each. I hope this helps clear the misinformation. Again, no offense taken. I appreciate the opportunity to clear the air.
VBR,

Hi Keith,
Thanks for the post,
Wow,Interesting keith.
I have listened to the Auricaps for about 4 months and find them very good.
Having compared them to the kimbers i do think they are better,
Wether the SP6 itself betters the SP9 is another factor which i should have mentioned.
The SP9 i had was real bad with the Kimbers.
The six has a beautiful sound.
What kaps do you use keith?
I find the Auricaps subtract very little but am always open to experimentation.
Here in the Uk Kimber are very well known for hi fi tweeks but not for kaps.
The Auricap give phenominal spech readouts on the net compared to Multicap and Rel.
Thanks,
Ian.

I am well aware that the AuricCap is very popular here at AA. I was using the SiderealKaps that I mentioned back in the mid eighties. They were a good cap at the time. It amused me when all the buzz was starting about the AuricCap to learn that it was the same cap with different leads that I was using almost 20 years ago.
Let me say that I am also well aware that taste is an issue with all of this stuff. My feelings are that it can be difficult to isolate what a cap really sounds like on it's own, when replaceing them in a circuit like you mentioned in your ARC units. I am a huge ARC fan myself having owned several of their pre amps and use one now in my own system. I worked at an ARC dealer when the 6 was being produced and feel like I have a good idea of it's sound.
Anyway, what I have been doing for some time is experimenting with some different caps in a way that has proven to be eye opening. I use a Vandersteen 2Wq sub. The sub requires that a high pass filter be placed at the amps input. The filter is nothing more than a calculated cap value. I have found that this is a great way to evaluate the sound of caps without outside influences. You introduce a cap into a place where there was none before and you really can detect is signature. This all started when I began to question the claim of transparency of the Vandersteen X-2 fixed in line filters. When they were in the system, it seemsed to rob it of some of it's magic, although I gained the added foundation and weight that the woofer is capable of. It just seemed to loose the clarity it had before. I started by trying a set of filters that a friend sent me made with a single InfiniCap. The Vandersteen units use a very cheap yellow REL cap. The difference was huge.Much closer to the sound of no filter at all but with the bass. I next built a filter using the Dynamicap. This time the difference was more subtle, but the DynamiCap was clearly better. The DynamiCap was more realistic in that it had even a bit better clarity and it's harmonic richness was superior, as close as I have been able to come to no caps(no filter) at all. I then built an AuriCap filter and compared it to the InfiniCap and the DynamiCap units. Granted it was good sounding in many ways. Much Much better that the Vandersteen REL cap X-2's but it couldnt match the InfiniCap filter. It seemed to subtract ambient and overtone information which left me with a somewhat dry sound. The harmonic richness just wasn't there, which flattened the presentation.
It sounded nice, like I said in many ways, I just felt very strongly that the InfiniCap was more lifelike. The DynamiCap is better yet. I will at some point try some of the new Cardas caps, which are well liked by Steve Huntley at Great Northern Sound.
I think this is a unique spot in the system to hear what a cap does or doesn't do to the signal that passes through it. Right now the DynamiCap is the very best I have tried. I have plans to use them in my amp and pre amp to replace the InfiniCaps that are there now.
By the way, I am using an SP 9 with InfiniCaps installed. My 9 also has an IEC inlet. Getting rid of the 18.Ga stock cord is huge. The amp is an ARC VT 50, which comes from the factory with InfiniCaps.
