Shall I add a preamp to my setup?


I newly setup a system with Thiel CS 3.7 speaker, driving my Sim audio Titan 5 channel poweramp, source with Simaudio cd5.3, I am very excited with the 2 channel performance, but it seems lack of warmth of vocal and extension of high, not enough airly extensions, base is fine. I doubt my weakest link is the Sherbourn PT-7010A pre/pro, all the above new gear has pretty much break my bank, I wonder if I should squeeze the rest of bank reserve for a descent 2 channel preamp in order to solve the problem.....the other choice is a better CDP, can someone walked thru the similar path give me some advice?

I particularly like the Synergistic Resolution Ref x2 active wires. Up from there the Acoustic Ref x2 active are more refined yet lack the impactful extension of the RR's. however this is by degrees only and the AR yeilds a more cohesive SS with better layering than the RR X2.

One thing to bare in mind here, is that 'warmth' in ALL areas (tubes, cabling, componnets) can lend itself to a muddy situation perhaps, if some care isn't taken along the way.

Once the 05 is in house, try some RCA or Simens tubes in it first. That may be all you need... and/or a nice pc on it. Maybe a AZ Sunami, or Mongoose (cardas Golden ref facsimile). Both of those moves will cost far less than the cables you want to add and might save ya some duckets.
I am ordering a pair of RCA VT-231 for +ve gain and mix rest by Sylvania vt-231, I might take your advice on pc later on, thanks, jim.
Those tubes should help a lot. they possess different attributes and should offset each other well. More ease would be gained using all RCA.... just something to think about.
Thanks for all your input and finally the Cary tube pre is installed with excellent result, its more harmonic on vocal, strings, piano, bigger soundstage, singer step forward to me couple of feet, last but not least, more airy and less harshness.

If I have to improve, thats the slight tip in the highs (I know its Thiel) and lower the signal to noise level (I can hear it with volumn tune to zero from 3-4 feet away), hopefully the RCA VT-231 coming in with resolve a bit. Any thoughts of other?

Thanks Jim, I am using Cardas Golden ref now. Put on hold for speaker cable unless a good pair of SR AR/RR comes up in agon.
Grandtech, on the VT-231's, if you don't shine up to the others, trys some black glass Ken-Rads.

I have a stash of the Sylvanias and Ken-Rads and always preferred the Rads. Don't know about the RCAs.

Let us know how it goes...
