According to Ray, it is a fully differential amp after the input. I don't really understand how, but that's what he said.

Hi Mr. Sasaki... There are two ways you can design the balanced amp when dealing with single ended input signal. One of them is taking the SE signal & running it through a volume control that has two sections only, one for the left the other for right channels, this way at least you are dealing with a volume control that has less problem in tracking & is easier to match the two sections than the one with four sections, as the one with four sections is almost impossible to match all four sections together. Going back to the pot with two sections, the output of the pot, Wiper, is going into a gain circuitry to determine the gain needed, then the SE signal is going to the phase splitter where the SE signal is split into two signals mirror image of each others but with the 180 degree out of phase, thus creating your positive & negative signals needed to go to the last stage which is the buffer. Margin of error is way less when dealing with a pot as good as the Panasonic used in the Protector, as it is easy to match the two sections as we said above.

The second choice would be, to feed the SE signal to a phase splitter, first, to get the two mirror image signals, the positive & the negative, then running the two signals of the left channel & the two siganls of the right channels, four in all, into the FOUR sections of the volume control, which is so hard to find well matched, & then out of the four wipers of the volume control to four buffers.

I believe the first choice would be a better one.

We all suffer as a result.

jamato8 seems pretty mature and can handle it.
I must say it does feel funny, that jamato8 has been called a "shill for RSA" and now Ray from RSA sends him (jamato8) the prototype to give us listening impressions.

But I gave Jude a hard time for excepting the Prototype GS 1000 from Grado labs as a gift, after a over the top review.

I'm sure your not the only one that thinks so.

Life can be ironic. Actually I think life is ironic most all the time. I had a patient today struggling for life after destroying his liver with alcohol. I was able to get him off the ventilator today and he wanted to celebrate with a drink, of water. :^)

I am sure you are a extremely good head-fier!!!!! I never in fact have been to a meet and not enjoyed everyone their, and I have learned more about audio reproduction here than any other place.( Internet or brick and mortar. )

With that said:..Sorry to hijack.

jamato how does this compare with the fiquest?

Since this is neither a MOT sponsored thread nor is jamato a MOT I consider this a valid question.. Let me know if comparisons aren't allowed in impression threads too..

Sometimes I've asked questions which are ignored and buried... So I figured maybe I'm doing something wrong like stepping past some line of acceptable etiquette. Hence, I decided I might as well take the opportunity to find out what I've been doing wrong.

Sometimes people start posts and they want nothing but praise for the item they have posted about or no controversial remarks. I think the MOT forum is one that needs to stay on target about the paid for by the manufacture forum but here is for general discussion but again some people have in mind what they want in "their" thread.

I haven't compared the amps. They both though are very, very strong on the musical portrayal of what goes into them. With some recent changes to the fi.Q I am still letting it burn in. It is all about the music and at some point I don't know if there is a clear "winner". I will say that so far the Protector is doing everything right and that is in balanced and single ended.

That's not really irony, and that doesn't really pertain to the question, though. I believe that the best way of pointing out a contradiction is to show the person in question how they did it exactly, but I don't want to go through the trouble of multiquoting your posts. I'm sure if you spend some time digging that you'll see you clearly contradicted yourself.

Closed headphones aside;
Why would something like an IEM, even a multi-driver one need a
balanced amp?
