Default good preamp

hi
I run a sound system in uk and i am looking for a good preamp to build to drive my 10 k rig. i have tried various shop equipment none of the seem to do the job no deep bass or clear mid range and sharp trebles. would like a circuit with seperate bass, mids and treble. can anyone help.
also many years ago (1984) before i got into electronics i was giving a home made 10 band graphic i opened it up to have a look insde it to find it had coil wound components same as a crossover but smaller to contol the freqencies. The unit was awsome i have not heard nothing like it since. also looking for a good graphics circuit
i have no formal quilifictions in electronics. but have learnt how to red circuit diagrms. i have built hundreds of projects some work many do not. latest being a 400 watt amplifier from aussie amplifiers this is before he went commercial and posted the curcuit diagram on the net. any information will be grate full

My JFET preamplifier circuit effect very well, treble clear, transparent. The strength and flexibility of bass, midrange level, more energy and electronic machine. This is the most ideal circuit of my life played

If you want a very revieling Pre, you need no pre at all. the nearst thing to this is a TVC transformer pre. I use a TemaadAudio TVC which is very good at around $450, but there are several others out there as well

Default good preamp

Each 4 JFET. Fully electronic tube circuit, economic and durable, can match with the high-grade stage, sound quality blameless

I think the OP is seeking a preamp to suit Pro. audio "10k rig". Home hi-fi types will not be suitable. As it is also preamp issue, it would be better asked in the Live Sound forum area.

Not sure whether the OP refers to a "10K ... Watts" rig or a "10K .... U$/Euro/GBP" one.
I'm more inclined towards the second option.

That was 5 years ago. What he really needed though was a new spell checker. Looks like he broke the old one.

Of course!!!
Only now I noticed it's a 2008 post !!!
I read it because liushuliang (who didn't notice or didn't care ) needlessly answered it so bumping it up.

It should say something about the poor quality OP that it went unanswered for 5 years ... and then only by mistake
