Crazy But Not So Crazie Idea.......

If you are going to produce an amp under the name "zerogain" then of course it has to be just a switching unit or a passive. otherwise its bonkers from a marketing perspective

Last time I looked, Harbeth were doing an integrated with tone controls .
Knowing Alan Shaw's respect for Quad, his liking of the tilt functions and views on amplifier sound I'd expect that to be a very good product.

Not sure what a ZG amp could add.

Alternatively, if you want the *perfect amp with decent tone controls, just buy a CA840A/2 and stop worrying.


* Perfect for the vast majority of loudspeakers - a few don't like being driven by a stiff voltage source.
 
i now wish to end this thread on the subjet of ignorance by richard , witch of course he knows everything, i will make this pre-amp for my self, never to marking but only for me, richard get an fing life, you need it,

I am just giving my opinion nando, the same as you are, but mine is based on over 30 years of design experience, but that doesn't mean I am always right :D
 
now now boys, can i please have a coment as my crazy idea to make this hi-bread tone contrl pre-amp, please tell me if you want speakers you ca buy my quoter wave floor stands in yew,
 
Yes sorry Nando.

I have the schematic for a Quad tilt control and will dig that out.
It is a passive design so has some insertion loss but with the output form dacs and modern phono stages it could worked into an entirely passive pre or an active one.

thanks rob, i can or with your very good help i would make it, it make take a little time but it will be worth it and you will have it to try, thanks rob,
 
I imagine some of those may even have sold a few units Richard. Unlike yours.
 
rob i have also a very first diagram of the slope control that AMCROM used but i think it's not as natural as the quad! you think ?/

Joseph, are you wanting a phono stage in the Pre?

hi rob, hope you are fine, i have the dreaded cold, anyway back to this pre- amp, i was in to minds as to have the phono stage in built or seperate m.m. m.c outboard! what do you think?
regards,
 
All inputs should be on slot in cards, so they can be changed if you want. Phono stage, line level, DAC, tape loop, even an ADC etc..
 
simon, doesn't that make it more digital than analogue? i will prefer more orientated analogue way?
 
Naim did it on the Nac32, 32.5 and 72 pre-amps and it has proved to be most convenient (and is a large reason for their continued popularity). By building the amp in such a modular fashion it allows it to be configured in the manner the user desires and circuit changes can be made very easily (even allowing A/B comparisons to be made between different elements of the circuit).

Can we not discuss speakers on the other thread any more? This seems a shame.
 
I must admit - I have what is quite similar to a ''quad tilt control'' as an Lpad on my crossover.

I've got it sounding flat in room (this definately helped), so some gentle EQ tilt is an easy way to help (sometimes) with a broad-frequency shift.

If you can build in a bypass to the controls, I'm sure this will be of interest to those who wouldnt want the added circuitry.
