This is a question for advice from a noob to the experienced people out there.
I have a Marantz PM6005 amplifier, B&W DM305 speakers,
and listen to music from files on a computer (soon to be replaced by a network drive)
or from music servers such as Spotify. So far, I have been using a computer (MacBook Pro)
connected through a jack-RCA cable, but found the sound quality not satisfactory.
I suspect that the bottleneck is the computer DAC and the audio jack cable.
To test this, I am about to get toslink cable to connect the computer to the amp.
First question: will this help?
Next, I would like to have a multi-room system, so I was thinking of Sonos Connect or Bluesound Node 2,
or something similar, in a similar price range, to connect to the amplifier. My second question is whether
this will further improve the sound quality, and which one would deliver better sound quality
(I do not believe in hi-res), and how big are the differences in the quality.
The third question is whether I'm missing something important?
Like a dedicated DAC, a preamp, or anything?
I would like to avoid buying any unnecessary things.
Excuse any possible confusion in the above questions.
Thanks in advance for your opinions.
