Port Fixed vs Variable from DVD player/Pre amp

Hi all. This may not make any sense but recently while playing CDs on a cheap DVD/CD player the sound cuts off periodically but ONLY when running through the line in of the port and ONLY when the port is set to Pass through from my pre amp. If I set the port to variable the music does not cut out. It should also be noted that on my metered pre amp the VU meters seem to always have a signal in that there is always movement. The CD player is connected to the pre amp via RCA cables and not into my pre amps DAC via coaxial cable as I am not sure my pre amp DAC works. Any ideas?

Hi @Mdhowes

If your turntable plays through the pre-amp/input-selector without issue while your CD/DVD player does not, that would indeed be an indication to me that the issue is with the CD/DVD player itself, as you say. I suppose it’s not entirely inconceivable that it’s a combination of the CD/DVD player and the pre-amp/input-selector, but my money would be on it being one or the other, and it sounds so far that it’s the CD/DVD player that’s responsible for the issue you hear.

I hope this helps.

Hi @Corry P . SOLVED. Yesterday I ended up running a touslink cable out of A Sonos Connect into the C2500 DAC as well as A Coax cable out of my CD player into my C2500 and was rewarded with uninterrupted and noticeably better musical bliss. Here is the funny thing CD player issue aside. The Sonos Connect is a source like my TT and CD player to my Preamp. From the Pre Amp I have Fed into a Sonos PORT which in turn is Y connected to both a powered SUB AND my Bryston 4 B (Soon to be MC452 Mcintosh) and then out to my Speakers. Now I have 2 options for streaming. 1 is using main system only via the DAC connected Sonos Connect with Preamp control OR any of the Preamp input sources through the PORT and therein my entire Sonos ecosystem (ARC,SUB, PLAY ones, Beam etc). I am not going to lie, I had considered getting a BS node to perform the front end task but am now satisfied with my current setup. After all, I really dont need any more clutter :)

I’d call it a pre-amplifier too, I’ve had several that are similar. I did note the dual connections for MC and MM phono cartridges which is a much nicer solution than a switch.

My experience goes way back to when a pre-amplifier and amplifier was the norm, the new integrated pre-amplifier/amplifier receivers were a new and in many opinions a lesser quality option.

Today many folks aren’t aware of the older tech and don’t immediately recognize the difference in a full featured (volume control and input switching) pre-amplifier (with or without RIAA phono inputs) and a dedicated RIAA phono only pre-amplifier.

@Corry P . Hey! Question for ya. If I run my sources from the preamp through to the Sonos Port set to variable am I in effect doubling the EQ capacities? (Pre amp control and EQ through to Sonos set with EQ enabled)? Cheers
