Daisy chaining Line Conditioners

I have some of the 'cheap' sort of conditioners..
Monster 5000
and several Adcon 515/525 conditioners.
When daisy chained the sound does tend to get leaner if on pre or power. On source (Cd the sound is ok either way. Video definitely gets clearer/less grainy picture with multiple conditioners.
Everything except the amp is into the Monster 5000 and four separate Adcoms are plugged into the Monster.
One for the computer,
one for the analog pre pre's,
one for the tt's,
one for the digital.
The preamp is direct to the Monster5000.

Sundance45, you have lots of line conditioning gear - do you daisy chain them?

My theory is that filter-types lend themselves to daisy chaining benefits whereas power regeneration units (e.g. Equi=Tech, PS Audio) may not benefit from adding filter-type units because they have digital outlets to reduce EMI/RFI which is the same functionality that the filter-types provide . . . Just a theory. Any advice?

Thanks for your replies folks.

yes I do daisy chain them with the exception of the Symphony Pro. For the reduction of EMI/RFI, I think the Symphony pro is the way to go.

At one time I had the Equi=Tech Q1.5, the Walker Velocitor, the Reimyo filter, the Sound Application Line Stage, and the Loricraft power supply. I tried many different combinations. Since the Walker and the Reimyo both are Quantum based and the Loricraft and Equi=Tech both balanced, I thought that using one after the other would sound poorly. Any combination of the Velocitor and the Reimyo was worse than each by itself.

The Loricraft is current limited , but plugged into the ET did not sound bad. Not great either.

The Equi=Tech did not like being plugged into the Sound Application.

I think there can be many unfortunate interactions between these various technologies, and it can be very frustrating to try all of them. With the exception of the Loricraft which I use on my Shindo Labs/ Garrard 301 tt, I have sold all of the other filters, finding the IsoClean system with isolation transformers and a filtering box to be superior although expensive.

My result are similar to Tbg. I recently tried a RSA and
a Audience adaptResponse. They both sound better on their own.
