I thought I was the only one using a Z-sys RDP-1 with my meridians...

Actually, I should have said RDQ-1 -- all the same EQ functions, but only one AES/EBU and one SPDIF input, more limited gain control, and no remote, none of which are any real issue when used with my G68. On the upside, much, much less expensive than the full dress RDP-1, especially purchased direct from ZSys!

I completely agree with your review of this product -- in a two channel setup, I have nothing else which produces a comparable improvement in the balance of Meridian speakers.

Untrimmed, the Meridians' tonal balance is not to everyone's taste. The Tilt control is a great little tool for adjusting overall spectral balance for each recording, but has not sufficient precision, flexibility or finesse to properly EQ the speakers for room, personal taste in tonal quality and recording quality. The ZSys doesn't interfere with the Meridians' performance or tonal control function, but used judiciously can make the subtle adjustments that transform the sound in a way each individual listener should like.

In addition, used with anything less than the very best of transports, the Zsys is totally transparent, and helps to reduce jitter, smoothing the sound noticeably. All this for a very reasonable price, IMO.

Unforunately, it does not pass multichannel signal, so it won't help with DVD players outputting DD/DTS (Zsys makes a multichannel EQ, but the price is heart-stopping!). But on two channel SPDIF or AES/EBU signal, I've heard nothing comparable.

PS to George: Should I have started a new thread for this?
