Tubes are neat and all but my understanding is the X5 is worth the extra cost. I have one and have zero complaints.

How so? I'm a full on newbie here so trying to learn more.

Currently planning to get a turntable and wondering if I would notice any difference between using a built-int preamp on something like the Fluance RT81 or going this route X2/X5.
