Thanks again. I've tried the speakers without the KUBE and they sound pretty good!! I guess I don't know if I am missing anything but the Kef recommendation is it must be included, for better bass extension and go enable minor alterations to H and LF.
I found the stuff below on another forum - it seems to make sense. Do you agree with the explanation?
"I guess I failed to communicate why your receiver does not have a tape
monitor. Tape IN is just a normal input for your receiver. When selected, its signal goes to Tape Out. Not your CD, not your phono signal, just the Tape IN goes to Tape Out. If the EQ is connected to Tape Out and you select CD, then the Tape out would output the CD output, and you have no way to listen to the output of your EQ. If you then select Tape IN to listen to your EQ, then you just changed its input from CD to Tape, which is effectively itself and your EQ lost the CD. Tape Monitors used to let you select a source, output it to Tape Out, then listen to your Tape IN without impacting the output of Tape.
To INSERT an equalizer into a circuit, one must have the ability to
1) take the line level signal out of the receiver's signal path, and then
2) INSERT the equalizer into the circuit and then, finally
3) RETURN the equalized signal BACK into the receiver's signal path.
This was happily controlled in days of old by tape MONITOR LOOPS. These were controlled by a switch on the front panel which would either keep the signal in the receiver or, when pushed, send it OUT of the receiver's signal path via the "tape out" and BACK INTO the receiver's signal path through the tape input. You knew you had a "tape monitor loop" on your unit when you pushed the tape monitor button with no equalizer and the signal disappeared. Simply having a tape out and a tape in does not mean you have the required "monitor loop", just two unrelated inputs and outputs."
Now, does your receiver have a "tape monitor" button on front, or not? If not, you're boned. The older vintage gear had a tape monitor loop so that you could use three head recorders, that allowed off tape monitoring. So the source was always at the tape out, if the tape monitorloop switch was to source then you heard the source from the
speakers. If you depressed the switch and the tape deck was set to output the play back head during record, then you listed directly to your tape recording from the tape as it was being made. That way you heard problems right away, and could for instance correct tape saturation before it ruined a whole recording. That same loop could run and equalizer and the equalizer could also run the tape recorder. You could buy a really nice vintage pre amp and amp.
Your other alternative is a an external amp, with the Equalizer ahead of the amp. There are good vintage options out there, or new units.
If you can rise to it a Quad 34 or 44 preamp with either a 303 or 405 2 power ampwould do you proud. You now have to be a bit patient to find one, but you would not go wrong.
I think I get it if that is all correct.
In the same post, it was also suggested that s single source, so my laptop into my Qute DAC could link straight to the Eq and then this connects to line in of amp. Would this work? I use no other line source so happy to commit to a single option.
Thanks again for your patience
