Fitting attenuation to the input of the amp stops this overload and allows a much more natural and dynamic sound (like LP), also an other benefit that comes from this is the volume will be nearer the 12 Oclock position for the same given volume so you have more fine adjustment plus the stereo image is much better as the volume pot is much better away from its start position.

Hi Brent

I believe you are right (Again...!!)

My player sounds much higher then the phono or radio input.

I also believe that positioning the volume pot near it´s end will give better sound overall.

How can I atenuate the cd output ?

My player is now unbelievably good sounding.

I am thinking in upgrading the drivers psu....

I am using fine pressings from ECM... The sound is fantastic but can not compete with the LP ability to produce a real soundstage with minute detail....

Sorry to say Simon, but I doubt whether cd will ever sound better than lp. In my experience the lack of compression on lp makes it soo dynamic and it has a life to the sound that cd just can't do. Admittedly an uber player like yours or Brents may get close, but for me a good vinyl setup is king (except when I snap the stylus by dropping it).

Lee.
Quite right.

I've never heard an expensive turntable, but whenever I hear vinyl I notice a common elastic-bass and rolled-off treble colouration. I expect this is what people enjoy on less-than-perfect recordings as it seems to sweeten things up. The effect is reinforced by the positive trait of a strong, physical bass and fine timing.

Those latter qualities CAN be reproduced on CD IMO, and what's more we can have stereo bass and bass all the way down to 20hz on CD, which is a bonus sometimes.

I recently attended on Vinyl fair in Lisbon.
The stands had real high end turntables with very high end amps. You should ear some heavy turntables to understand the differences. The sound is much more coherent.

In terms of LP v CD the debate can go on forever. What I will say is a modest turntable will outperform a decent cd player.

With regards to my own cd player which you know has had the odd mod or two done, well it's up there with good turntables BUT only on my very best cds that have no or very minor compression , are dynamic and of course well recorded to start with.

Cds like 'eric clapton unplugged' and 'jazz at the porn shop' in XRCD are superb, where something like Amy Winehouse just went in the bin as it was so distorted, bet its really nice on vinyl.
Amy CD sucks.....

Here is the simple circuit for the -11db attenuator (best for most people).

Here are the RS links for the resistors 6K81 and 10K0

Either fit in the end of the interconnect or in the input section of the amp, one per channel.

Thanks for the info Brent. Do you reckon that will be suitable for use with a 50k pot? That's all my pre-amp is.

Lee.

Before I answer I need to be clear about your setup is.

Is your pre amp just a pot of 50K? or is it a normal active pre amp?

You have probs told me before but my memory sometimes fails.

Brent

After one year modding this player (following this forum) it presented lots of dynamics, fast transient response, lots of bass and trebble but a shallow stereo image.

Than came Mauro´s mod and finally I got stereo separation, real imagery and credible sounstage.. but the sound was very edgy.

Finally I did the accoustica.og modd and averything came into place.

My CD53 sounds unbelievably good.

Regards

Ricardo
