Question about using an EQ in my HT

[franklinpross]

I honestly found that the use of an EQ in my HT for tapes and Lp's really
makes a difference.

Of course, with 5.1, or Bluray and HDTV - it's wired in such a way
that the EQ does not function.

I use my Pana 310A as a very good CD
player thru the EQ.(2 CH) ( I love to fiddle with the digital sound of CD's boosting
this and lessening that. {bass/midrange})

The Sammy player (Bluray)is flat(no EQ) It would not work anyway because EQ's only process 2 channels.

Q: I love recording on Metal Tape. CD's on to Metal is quite good.
After I added the EQ in 2005, I can no longer record decently.
I tried to default the EQ recording flat. But sound is not good enough I just can't think this one through.

Please give me some input short of disconnecting all cables to record. - - thanks.
