The 610 requires seperate speakers, and Ruark is veering off their beaten path a bit. So why would you NOT want a CD player? Cambridge did it with the Evo? Marantz does it.
I'm dead sure some 610 buyers would buy a turntable too - a Rega with a nice wood finish plinth would not go amiss.
Your question could actually be why would anyone want a 610??? Because until now Ruark have only been making speaker playback systems, be it internet/DAB/FM radios or whatever.
They've identified a certain segment in their market who wants a bit more flexibility. So now they can choose their own speakers. And the 610 has a built-in phono stage. So again, why not a matching CDP?
My comment was based around what the 610 actually is.
It's a streaming receiver with Bluetooth.
If going down the streaming route I could not understand why anyone would want a CD player as well. Most people into streaming are trying to get away from physical media so same goes for vinyl.
As to the quality of their inbuilt phono stage I cannot imagine as anyone likely to want to add a turntable to these things might very well already have one in the turntable they own.
Their ability to integrate their own cd transport into their system leaves me in some doubt as to their QC set-up and made me wonder as to whether anyone actually auditioned these products prior to purchase.
Whilst Ruark, in the day, made some very good speakers they are not renown for amplifiers nor streamers so simply questioned why anyone would would want to build a system around a R410 would do so any why without auditioning.
It is indeed unfortunate, these days, that a company can not produce two products that will work together seamlessly.
