@brianyee5504 To tell you the truth. Most people think they know what they want but they really don't. They only believe they do. Usually it ends up with something very different. The only thing to do is start talking but need to make sure you talk to the right person. That is another very difficult part of the game.
@@angela-gilbert …which is why I watch your material and haven’t touched an “audiophile” magazine since discovering you. As far as I’m concerned, I feel I’m still at the “On-Off-Louder-Softer” stage of the game. 😆
@@brianyee5504 Enjoy the ride but try your best not to pay expensive tickets. Some money yes, but don't get suck into the latest and suppose to be the greatest. If it involve paying a lot of money, they are not great for you. Only great for the seller.
I so enjoy all of the details that you put into your designs. Icicles and helicopter landing pads are artistic but practical features. The other thing that I have noticed is your expressive way of communicating with your video's. Your face expressions show so much into your amusement with life.
@@donnieschmutzler9221 I wouldn't pass for acting school. I couldn't act base on script. Someone notice I am different between my solo videos and those with others. You probably do also. When I am relax, video length got long because I couldn't stop talking. Just a side note. Someone is going to get some strawberry yogurt in his amp. I havr scheduled that video for next week. 😍
Awesome AGY...I always asked why don't Pre amps have more outputs and because bi amping speakers are so abundant it should be standard...AGY always one step ahead
@@greenlanternseven It is about whether the dealers want to sell it or not. It is all about whether they can sell more boxes. If marketing say they cannot sell it, no one would do it.
@wstagner No challenge is like working in production line. What is the point. After that said, I have to work on something that I personally have an interest. Otherwise, it is impossible for me to put any effort into it.

@@mordante01 They are big enough for some of the big RCA plugs. Unless you are using super crazy big plugs. There is reasons I place them at those distance. One of the teason is the ground taps can be soldered together without using extension.
@@iokuse8498 No, they are not the same. They are both external capacitor packs. However SP Cap Pack is for lower voltage device such as preamps, phono stages, DACs and input stage of an power amp or integrated amp. FCF is for output stage for a power amp or an integrated amp. FCF is also available in various voltages for different level of power output.
I have a question; was this specced entirely by the customer or was this a collaborative effort with you saying “Yes, we can do this and no we cannot do that but I have a suggestion”? Otherwise; I would think this was a project between two electrical engineers…
The customer knows what he wants. He can buy multiple equipment to do the same thing. Spliters and all that. He has been watching my watch for a year. When he was looking for a new preamp because his old one was not working the way it should. He approach me and asked whether I can do what he wants. He told me what he wants and I said no problem and then added some seasoning to the steak. Or, I prefer to say I have added ketchup, yellow mustard and a bit of redish to the hotdog. That was all. No need to have two engineers to get involve. In fact, no engineer was involved in this project. Since I am not one.
u dont really need kilograms of capacitors in there if u use power supply voltage regulators 7815 and 7915. but it wouldnt be audiophile gear any more, just boring professional equipment.
Have tried using 78 and 79 regulator long long time ago. They don't sound the same as without regulation. It has been proven by professional audio people. Not from the production side but from the mixing and mastering side.
@@angela-gilbert i dont see how regulator noise could be an issue with the modern high CMRR op-amps like the ones ure using. but there is a circuit called capacitance multiplier if u dont want any regulation.
@@echelonrank3927 If you are only looking at numbers and don't listen to the result. All of your theories work great. However, some of my customers actually use their ears. Many of them are in pro audio and use their hearing to make a living.
The capacitors are not for voltage regulation, they are for the collection, storage and rapid distribution of energy. If you were able to sit down and listen to how one of these worked, you'd understand. Same thing applies to a capacitance multiplier... theoretically it works, but in a real situation again does not help with storage or distribution of energy. So yes, rows of capacitors make a difference that is easily audible.
@ how much energy are we talking about here? its just a preamp. it doesnt need kilowatts of instanteneous energy stored or distributed anywhere within the unit. the claim that something like this makes an easily audible difference wont withstand the rigors of scientific scrutiny.
It’s items like this that makes your videos so unique and enjoyable to watch.
@@brianyee5504 Not everyday items for sure. 😆
@@angela-gilbert at this point in the hobby, I wouldn’t even know how to spec a preamp like this with you. 😆

@@duncanwilliams5040 Glad you enjoy the videos. I am trying to push as far as I can go without going too far too fast.
Looks like a masterpiece. That's a very lucky customer.
Thank you - I find your videos educational. Much appreciated.

This is a great piece. Love it.

I enjoy these longform videos, i hope you do more "tours" of your gear.
@@suwatt6019 I will when I have something to show. I also need to be in the right mood to do video. If I am not relax I can't talk and think straight.

you are genius
nice, can you add a pair subwoofer output and high pass filter for the main speaker amp ( can be switch on and off )?
@@donnywidodo8874 Yes, I can do that.
Very nice, my only remark is that the SE inputs are too close together.

Close up to the camera you look tired.
Thank you for taking us through the design and build.
@@fredflintstone8048 Do I look tired? May be I was. Been working and thinking 18 hours a day.
what's the price point we are looking at?
This praticular preamp is USD4,500.00.
@angela-gilbert is it going to have syncing issues with bi-amping?
@@MasterofPlay7 What syncing issues are you thinking? Are you thinking of upper and lower not being match exactly may cause time delay, etc.?
@angela-gilbert yep
@MasterofPlay7 The upper and lower circuit is exactly the same.
So sp cap and fcf is same thing ?
@@iokuse8498 No, they are not the same. They are both external capacitor packs.

Ok I have pre amp and dac but not Angela ....Is there sp pac mod for those devices like wu audio pre amp and elac dac?
@@iokuse8498 Possible yes. But we have to look at the actual unit before we can give you an idea what we can do. Either internally and/or externally.
