Phono Stage question


I have an Audio Research LS - 7  Pre Amp with no phono stage...
Can I connect the phono stage that is on my  Denon 757 Integrated Amp to this Audio Research pre amp ?
Thank you.

Yes. Take the phono stage out via the ’tape out’ on your Denon to any input on your ARC.
@slaw Phono goes into the Denon and comes "out" via the "Tape Out" RCAs (fixed volume, line-level signal). The Denon signal goes into any line-level input on the ARC and gets passed to the amp.
I’m doing this with my McIntosh preamp’s phono stage into a BAT integrated. Works well...
To dweller:  Thank you for your response. I have one other question :
Phono goes into the Denon....tape output goes into the Audio Research Pre amp.....is that right ?
Also... the Denon will have no speakers connected to it...will this hurt the denon amp ?
  Thank you.
The Denon will be fine! Unlike tube amps, SS amps don't require connection to a speaker load!
@rocky1313 - Yes, you have the correct sequence. Also, there is a "standard" common to all (most?) electronics called "Line-Level". It is, I believe 3-volts for RCA type outputs. Some pre-amps, integrated amps and even some receivers have something called "Pre-amp out". This is a variable-voltage output and is typically used for sub-woofers so when you turn the volume up or down, the sub-woofer matches the volume of the rest of the music. "Tape out" is a constant 3-volts (I think it is 4-volts for XLR or "balanced" connectors). You just don't want to plug a "line-level" output into a "Phono-In" input. Phono-in does equalization to the signal before it sends it for amplification.
Oh Gawd...  Why would you want to?  Your ARC preamp is a wonderful piece and the Denon is Best Buy grade.    If you need a phono stage, there are any number of affordable pieces of a similar level of quality.  I'm very fond of what you can get at http://tubes4hifi.com/ because it's a very good value.  You can even save some money if you build it from one of their kits.  They can also build it for you for a modest amount extra.
I'm doing just that and with great success (IMHO). In my case I'm using a vintage Sony preamp (TA-e77es) as a phono preamp as it offers gain for both MM and MC cartridges with two loading choices for the latter. It is virtually noise and distortion free and drives a Sony receiver with line in and the preamp out driving a SS or tube amp of my choice. So much flexibility and despite what purists might suggest, no noticeable distortion even with all of the electronics in the path. The receiver amp and speakers are not in the path and it will not, as suggested by others, be harmed by this arrangement. Go for it and see how it sounds to you!
