CA Azur 840E preamp or Vincent SA-T8 for MC402 ?

Hello,
I am a bit new/naive in the audiophile world, and definitely need some advice and feedback on what can be done to improve the musicality of my equipment.
I bought a MC402 a few months ago, and am still trying to get the "wow" out of my equipment- So far i still think the treble is too on the 'hissing" side, and soundstage is not quite there. I tried a direct connection between the Oppo 95 and the MC402 : clarity is there, but still hissing a bit. I am thinking a good preamp may help; but which one?
The budget is around $2.5K max - Constraints are: as best musicality as can be obtained in that price range, fully balanced connections, remote control.
So far i found the CA 840E, and the Vincent SA-T8. Any recommendations?
Thanks

What's the rest of your system? Do you already have a preamp? If you can run direct,it's probably better to run direct than to put a mediocre preamp in the system. Maybe something else needs upgrading, probably speakers. At entry level hifi, the speakers are more important than anything else, followed by power amp.

Hi there,

The main pieces are:

. Vienna Acoustics Mozart Grand,
. McIntosh 402,
. Oppo BDP-95.

The current "pre-amp" is an Onkyo TX-SR875 that i am in the process of replacing.
So far I have tried connecting the Oppo directly to the MC420 (tried balanced and RCA), and also using the Onkyo as the preamp. I also used an Emotiva XPA-5 as the amp instead of the MC402 for testing purposes. The best results are the Oppo --> MC402, but there is still too much of 'ssss' to my taste.
I have changed interconnects also. Either the MC402 is not delivering, or i am missing a piece, which i am thinking (hoping) is the preamp. Or is it that the MC402 is supposed to be putting out this "ssss" sound ?

Any help/input is welcome, as i am a bit at a loss.

Thanks in advance.

If no one has used the CA or Vincent, could anyone suggest a good preamp in the $2500 range for the mc402 ? At this point I am on to both tube and SS. I forgot to mention that HT bypass would be a plus.
thanks

I've a Vincent SA-T8 that I bought from a fellow audiogoner. This has been upgraded by upgrade company and I use NOS tubes that I got from the original owner. YMMV, but in my system pairing with a PMC AML-1 speaker and W4S Dac-2, vincent sa-t8 brings out the magic in my system. The preamp totally changed the tonal character in a subtle and obvious way. I don't think I can ever go back. They are fully balanced and comes with remote. I'm not sure whether a preamp change will solve your hissing problem though.

Thank you for your reply Radiohead99.
My hearing may be the culprit for the "ssss" sounds being too pronounced. I was hoping a tube preamp would mellow out the MC402 a bit, and the SA-T8 in on top of my list. Have you ever have replaced tubes since the upgrade ? If so was the full process fairly painless (from finding the tubes to the installing) ?
As the Vincent does not seem to have a HT bypass I am still on the lookout for potential others for a bit before making the final decision. It could be frustrating a bit though, as the choices seem to be ridiculously expensive in most cases.
Thanks
