Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Power Conditioning on DSP8000SEs

I watched the video last time, no explanation. First thing I read on the website is instantaneous current delivery ensures maximum performance and electrical reliability, doesn’t say why that’s important. Next noise reduction, it allows components to operate in a noise free environment. Can noise be otherwise defeated, downstream aren’t designers minimising that anyway? What exactly might noise do. Too many presumptions too little explanation. Ferrites anyone?

Definitely something in it but something Meridian missed in their 50k speakers, must be kicking themselves.

I’ve been reading about Low Drop-out voltage regulators, they reduce noise, ripple in a very measurable audible way, trouble is they are $18 each. Not exactly drop in though.

Hi Bruce,

Are you in a position to repeat your Power Conditioning experiments with 8000SE by applying same to 7200SE and 5200SE models, or for any reason would you not expect this to be applicable?

Thanks in advance of your considered reply.
Hector

Not at this time, however I could do it with some 5500's and 5200's

Cleop, which PS Audio gear did you try? Was it a Power Plant or just a Dectet? How did it work out?

Thanks,

Rick

I did end up trying the Shunyata Denali 6000S with the DSP5500 and DSP5200 legacy speakers and observed results similar to those with the 8kSE. I would even say that it even tamed some of the notorious bass from the 5500's. If you are considering buying new speakers or amplifiers, I would encourage you to consider a in home demo of the Shunyata products first. It might just be the sound you seek.

Thank you Bruce.
Good advice, especially to anyone considering 5500's. I have never considered these for serious 2 channel listening as the bass IMHO is not controlled and these are IMHO only really suitable for cinema 5.1 and above. If Shunyata products change the characteristic of 5500's I would be very pleased to hear the results.
As for 5200SL speakers would you expect a similar result or would EBA etc reduce any possible improvement from addition of Shunyata Denali kit?
Conversely would 5200 SL upgraded to 5200 SE be a better option?
Hector

With the 5500 the bass bloat was reduced but better defined. 5200SL or SE would have similar positive results as the 8kSE as all have EBA. I find that I don't have to listen as loud as I used to in order to pick up on small details.

Thanks for the quick response Bruce.
I think if funds are available I will upgrade 5200SL to SE as this is a known entity to me.
Not brave enough to step into the "not understood by me" technology area.

It was an earlier Power Plant, not one of the latest models (which I understand are significantly better). I felt the PP reduced dynamics and added a subtle sheen to the music, even when only front-end components were plugged into it. A Sound Applications Reference Line Stage I had on hand was more natural-sounding, although it too constricted dynamics when the DSP8000's were plugged into it.

The only line conditioners I've found that do not seem to restrict dynamics are the latest Shunyata products, the Triton v3 being noticeably cleaner than the Denali's. I believe Shunyata is releasing their new Typhon QR this week, which is designed to be paired with a Triton to form Shunyata's best line conditioning system. The prior version of the Typhon worked in parallel with the Triton (i.e., it was designed to be plugged into one of the Triton's AC outlets), but the new version apparently uses different technology and works in series with the Triton (i.e., the Triton is now plugged into it, and it is plugged into the wall). I have one on order and will report back after I've had a chance to evaluate it.

Agree Bruce. 65 is a very noticeable bit louder in both my setups.

Is anyone using any of the recent PS Audio PerfectWave or DirectStream Power Plants with 8ks (or other DSPs)?

i.e. the P5, P10, or the very latest (greatest?) P12, P15, and P20?

These are supposedly designed to provide extremely high peak current, the latter three providing (allegedly) up to 90kAmp, 120kAmp, and 180kAmp peak surge current. (The PS Audio data sheets appear to have embraced Meridian accuracy and consistency in terms of the specs, but a minimum of ~100,000 Amps seems to be the deal.)

I have one datum point of a completely satisifed user with a P10 and 8ks.

My experience with the PS Audio P10 is that it worked very well with my 5500's but seemed to have a negative impact on my 7200's.
I found that Shunyata products work well with all of my Meridian gear.
