Bi-amping via Y-cables sound quality

I have a Linn Classik Music system and a Bryston 2b LP in a bi-amp configuration (The classik drives the tweeters while the bryston drives the mids) using Nordost Red Dawn interconnects.
I am thinking about getting a second bryston 2b and using the Linn strictly as a pre amp. Since the Linn only has 1 set of pre outs and the bryston doesn't have any pre-outs, I would be forced to use Y-cables to accomplish this.
My question is will the sound quality diminish by using Y-cables?
I really do not want to get a dedicated pre-amp because i like the fact that the Linn has a cd player and tuner built in a compact size.

Most preamps that have two sets of outputs simply jumper the two sets of jacks together internally. So electrically there is no difference between that situation and using a y-adapter externally (assuming the y-adapter is of good quality).

Keep in mind that the load impedance seen by the preamp outputs will equal the input impedance of the power amps divided by two. That should be ok as long as the power amp input impedance is not unusually low, or the preamp output impedance unusually high.
