Thanks Stanwal, Tom,
What I´ve noticed these last days is that the Rega Ear sounds actually much better, less hollow in the middles with the Rega Planet CD player. I was using it before with the Quad 99 CD player. Perhaps the problem was that the Quad favors the middles, which are the strenght of the Quad amps.
Passive preamps- that´s just what I am getting into now. I just purchased a pair of Quad 12L actives, and apparently I would need a passive preamp between it and the CD player.
Thanks again,
Fernando
