hair brained idea and a hello


I was wondering if anybody had any info for some hair brained idea i have.

Right now i have a project rpm 5.1 with the stamdard pearl needle, rollunning into an upgraded interal cambridge 640 with upgreated sound chips and high quality ports.

Now i cant evenenjoy rather bright sounding vinyl sound.

I was wondering if anyone has "daisy chained" for the lack of a better term a tube preamp and a solid state amp such as the cambridge.

I am interested in what kind of change i would get at all trying to daisy chain these amps or if somebody with more knowledge or experience then i, as im a mid 20 year old just getting into this whole audiophile side of enjoying vinyl.

-any reading, knowledge, anything would be greatly appreciated.

Thanks,

Yes, many, many, many people have used a tube preamp with a solid state power amp. Just mind your impedence matching. Minimum recommended is 10:1 ratio of amplifier input impedence to preamp output impedence. The higher the ratio the better the results.

Since you seem to be a Cambridge fan, let's use the Cambridge Azur 651A Integrated Amplifier as an example. The amplifier section has an input impedence of 47 Kohms, so any preamp with a output impedence < 4700 ohms will work fine. Remember the higher ratio is better, so 20:1 is better than 10:1, which means a preamp with an output impedence of 1000 ohms will work even better with this amp.

Have fun!!
Jmcgrogan2,Very good point! Ive had good results with a tubed preamp and SS Amp as well.
Thanks for all the help guys. I have a feeling my speaker system is my low point right now.

My system is set up like this:

My RP project.rpm5.1 goes into the upgraded campridge 640p with the upgraded sound chips and this goes into a yamaha ysp-1.

I did this as that is what i had around for a sound system in the front room where the vinyl is listened to the most.(plus allowing for the other inputs)

If im getting my information right the sound board on the ysp-1 is becoming my amp nullifying an added tube amp.

So, in order to marry this cambridge 640p and a tube amp i am guessing i have to dedicate a new speaker system to allow the pre amp and amp to get the sound im wanting wantingspecifically for the record player.

The warmth of the tube would be killed by the sound processor of the ysp-1, is this the correct thinking? Or, is my chain of equipment incorrect?
The Yamaha sound bar is a designed to substitute for multiple speakers to create a pseudo-surround set-up. It is not designed to optimize sound quality for 2 channel listening. You will almost certainly need different speakers and I would expect you would hear a substantial improvement in sound just w new speakers, using the amp in the Cambridge.
