Preamp for Quad 303 with Ls3/5a or Rega Elicit?

I doubt if anyone else has used this particular combination and even if they had they would not be hearing it with your ears. There is really no way to predict in advance ,with any degree of certainty, what any particular group of components will sound like. If you like the 303 one of the matching Quad preamps would be good, they have one of the rare tone controls that actually work. Remember that they will need DIN adaptors with RCA outputs. Otherwise, far too many to list. I haven't heard the Rega, I used the Quads for years and was a dealer and found them good value and reliable. I also sold the 3/5As but I was using 405s by that time.

Thanks for your reply Stanwal, I was starting to feel lonely here!
I was thinking about a Quad QC24 but it lacks a headphone jack, not sure.
Is the quad 303 easy to match with non Quad preamps? Thanks!

Csacred, The answer to your question is no, the Quad 303 is not easy to match with non-Quad preamps. The Quad 33 is the match for your amp, but you might try the Quad 34 preamp or possibly the Quad 66.

You generally have to stick with British preamps, and Quad is of course a perfect match to Quad. The issue is that Quad amps were desisgned with input sensitivity of 0.5v to drive to full power. Most American preamps have input sensitivity in the 1.5v - 2.5v range. So American preamps will typically overdrive the 303 beyond very little rotation of the volume control, with normal sources. Conversely, a Quad preamp used with most American power amps will not be able to drive them to full power out.

There are many British preamps that were built to the assumption of a 0.5 - 0.75v input sensitivity. I have a beautiful-sounding Audion tube preamp that works perfectly with a 303, but it was unusable with a pair of Audiopax 88 monoblocks I once owned.

You can widen the range of usable preamps with the 303 if you use in-line attenuators, like the Rothwell RCA - RCA units with 10db reduction in gain.

On the other hand, if you have a disc player with volume control, you can directly drive the 303 with no gain deficiency.
