Default what are you thoughts on zstage from decware?

Audiophile Tube Amps and Tube Gear from DECWARE

do you think this is a good design? looks simple enough to copy for my first diy preamp, and i do like how they worded their ad!

Hi,

DECWARE is famous for ridiculously over the top claims, if you like
that sort of thing then buyer beware, the reality is never true.

No way, in my modest system, would that improve my CD player.

You can add a triode based buffer for far less, its your wallet.

rgds, sreten.

CD player is a Cambridge Audio CD4SE, it works just fine.

i only use a dac so a preamp is a must. from what i understand, lampizator line stage is a glorified srpp, correct? i wonder if the circuit exhibits typical PP sound which i'm not too fond of.do you think aikido is a better choice for the smooth euphoria of SE sound that i'm always preferring?

how many srpp circuits have you built? can you describe what you mean by "typical PP sound"?

none, i'm afraid. i think of typical pp sound as being more linear and less distorted than SE. i need a preamp that has plenty of bloom and 2nd order harmonic saturation- 'tubiness' i should call it since i have no right to get technical with my lack of knowledge in this field..

NOOOOOOOOOOO!

Definitely more of a tone control than anything I would consider allowing in my own system.

The solution here may be a better dac, this kind of band-aide IMO is really the worst of all worlds, hiding the shortcomings of a bad analog path or other sins in the DAC with an incompetently designed tube stage to add some pleasant sounding colorations to an already apparently unpleasantly colored source. In the end what you loose is some of the music...

With you there Kevin, it's not true to the source and a band-aid fix, better off fixing the fault of the source instead of colouring it and losing focus, definition, control and dynamics.

Cheers George
