Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Thread Like Summary - Choice of Processor ( 561 / 568(.2) / G61 ) for 18 bit DSP’s

Appreciate members thoughts and opinions on choice of processor with 18 bit DSP5000’s & 5000C......


Main questions : is there an advantage in having the upsampling capabilities of the ‘go to choice’ of 586 (.2) over a 561 as both will be using 18 bit out only ? I understand the ADC in the 586 is probably superior in the 586 variants.

The G61 is a bit of an outsider choice as I have a preference for remaining g with the 500 series form factor, but has the benefit of room correction

Following house move, now able to set up a reassigned cinema and music system , adding a processor and rationalising what kit I have ( and hopefully moving on some stuff to compensate ) Background info - System for music and cinema in living room ( 5.5m x 3.6m ) Utilising existing kit audio - 500 cd source, airplay via Airport Express, video sources - Sony BD video, humax sat. etc

However, the home move that has enable the change has also added a financial constraint and along with covid19 impacts, the wallet isn’t as fat as would be ideal !!

Thank you muchly in advance

Hi Gary,

Dependent on budget, I would look at the processors in the following order:

561 - Very cheap, has plenty of inputs, max output 48K
568.1 Cheap, limited inputs, can do 96K (if I remember correctly, to fronts & center only)
568.2 Mid-priced, cab do full 96K to all outputs
568.2mm Mid-priced, limited inputs, does full 96K and had multi-channel input (for connecting a HD621 or Meridian DVD player)
G-Series (G68/G61/G65) - Plenty of inputs/outputs, some people prefer 500/800 series sound, make sure PSU has been replaced recently!
861v4 More expensive, customisable for inputs/outputs

You probably need to see what's available and what's affordable for your budget. I would personally be looking for a 568.2 or 568.2mm if I had longer-term plans to change out the DSP's for 24bit versions, but don't rule out the humble 561 - it was the first 'serious' processor that I had and was a major step up from the antique 541 (Dolby Prologic only). It is still in use, driving a pair of M3's!

Good luck with your search.

Cheers,

Steve
