To further improve the sound. Didnt you suggest I put the silver in the preamp rather than the main amp to begin with? ie:

Not that particular unit, but I've used the AD825 in many upgrades. It is a superb chip. Fabulous value for money, but hardly competitive with the preamp I'm suggesting to Tigerscent. The preamp I'm suggesting is full discrete transistor, using zero global NFB. It eclipses every OP amp based preamp I've ever seen (and most valved units as well).

How do you know it will improve the sound?

No. Read my words again.

Because silver conducts more efficiently - moreso than copper or gold or nickel, and every time I have used it, I notice a 'airy-er' quality with more precision/detail and sense of realism in the soundstage. I have rewired a pair of ProAC tablettes using pure 99.9% silver annealed, and the difference is a noticable crispness in the output.

I experimented with putting the same silver strips in the + terminals output stage of the 550 bolted onto the circuit board rather tightly, and the sound was actually more transparent and richer to a noticable degree. Peter suggested if I was going to use silver strips; that I use them on the negative polarity also, in fact from what I recall.

Its good to see you are onboard regarding the valve pre-amp : we really need your expertise to get it up and running, and then compare with the ME preamp, which is my plan in fact, so we can document the results and comparison. I am waiting on the Jadis inspired clone. I am looking forward to your further suggestions in getting it successfully off the ground with total and optimal inductance matching with zero distortion and compromise.

I know we can do it, with your expertise in the equation.

Oh, how dissapointing - and here I was communicating the fact that you were indicating using silver strips in the ME pre-amp. I am certain however, were you to try it, that you would notice a significant enough difference, at least to the order of a minimum of 5% overall improvement in the realism and dynamism of the sound, if not 10 to 15%. Try it, with the right grade and treated silver.

There is however, a certain science and method to preparing the silver strips for audio with regards to annealing the silver before use.

Silver is 7% more conductive than copper. A marginal improvement which can easily be addressed by using 7% more copper.

Its good to see you are onboard regarding the valve pre-amp :
I AM NOT ONBOARD WITH THE VALVE PREAMP.
I AM NOT ONBOARD WITH THE VALVE PREAMP.
I AM NOT ONBOARD WITH THE VALVE PREAMP.
I AM NOT ONBOARD WITH THE VALVE PREAMP.
I AM NOT ONBOARD WITH THE VALVE PREAMP.

Is that clear enough?

You are wasting your time. Use an ME preamp with your ME550. It will provide far superior results, compared you some home-built POS. You cannot hope to achieve the results that are possible with an ME preamp using some crap you bought off eBay.

I am not going to assist you with getting some POS valve preamp to do what it was never intended to do. I will loan you an ME preamp, anytime you wish. Unless you are prepared to pay for my time, I will not be assisting you with your POS valve preamp. I run a business. My time is valuable and I tire of those who fail to listen to what I say.

I've told you what you need to do. It is now up to you.

Not gonna happen. Use an ME preamp.

No. There is no benefit in doing so. Many have tried in the past and no improvement was noted under double blind testing situations.

I have better things to do with my time.

So Zaph; what happened? you were oboard before and so keen to help with the valve pre-amp and related issues, showing great concern about performance and offering suggestions for improvement - what changed? I know you found it challenging, but now is not the time to get faint-hearted...

We need you to stay onboard and see this whole thing through..., and not jump ship halfway through...

I was looking forward to your ideas/design regarding a SS buffer section for the valve pre-amp. Im sure you could come up with something fairly quickly. You need to take heart, eat well and continue on in the pioneering spirit of progress - this is how things happen and the world is changed.

You, in a small way, are part of that progress and change..., and we are looking forward to your input, advanced thinking and design ideas...

Nothing happened. You just don't read what I write. You need an ME preamp, or similar, low output impedance SS preamp. A valve preamp will not do the job. AT THE VERY LEAST, you need to try a suitable preamp BEFORE you embark on your silly project.

No, I was not. Not ever. I was trying to point out just how stupid your idea was. I have now ceased using polite language, so you do not misunderstand my words.

I see it as a complete waste of my valuable time. You seem unable to listen to what I am saying to you.

Yadda, yadda, yadda. Just buy or borrow a suitably low output impedance SS preamp. Job done. Stop wasting my time and yours with silly notions.
