I need your suggestion for a Preamp.

The power amp is a Levinson 431, driving a pair of B&W Matrix 801 S3. I am using a Levinson 390S CD processor to drive 431, the sound is not too bad, but I need a couple of more inputs as I intend to use a TT and add a blu ray player as well.

Your ML431 only needs 1.8v in, for full 235w output!! and is 51k input great for a passive volume control. Your ML390s gives this easily and the balanced 4.7v, and your 801’s are 89db, why not just get a source switch box, and a high gain (60db) phono stage instead
Here is a quality one, there are are many configurations at the bottom of the page with and without VC if you go with a volume get the 5k or 10k one to suit your 51k ML431. http://www.goldpt.com/info.html
With the phono maybe go the SA4M dual mono as phono cartridges are never balanced. http://www.goldpt.com/sa4.html

You will be happy with the Ayre and their service and support is great.  I own an K-5xe driving a Proceed HPA-2 amp (which was sold by Madrigal, which at the time owned Levinson, and is basically a Levinson design - 250w/ch at 8 ohms).  The two match well.  I went with the Ayre for the same reason - cost.  Have no experience with the Rowland products.  Good luck.

This thing is incredible as a preamp:

Just saying.
I did notice you’ve started 6 threads, with over 80 members posting answers to your questions, yet you never come back and reply to any.
You need to be a bit more receptive to people that have taken the time and effort to answer your questions, even if you don’t like what they give you.
