Audio Research or Luxman?

Following recommendations from here, I purchased a Chase off ebay, but the unit doesn't appear to be compatible with my Luxman because I can only use the main-in on the Luxman. According to the Chase owner's manual, the volume setting on the amplification device should be set to half volume. I can't use the volume control on my Luxman because it is faulty along with the balance pot. 

Is anyone interested in buying my Chase? 

audiojerry,

I ASSUMED you had more than one source equipment, thus I mentioned the Chase Unit.

We are talking about getting you listening until you find someone who will repair the Luxman’s internal volume controls someday, correct?. After that, you may still want to use the Chase for it’s remote features. (4 inputs, volume, balance, low volume loudness)

......................................

Now you are going straight into the 507’s Main In with a source component? It’s not too loud? Then hook up the Chase, it will be just fine.

In any case, I think you should try the Chase before you part with it. Chase’s default volume is low, if not too loud you are all set. If too loud, that’s a problem, you cannot start with the Chase below it’s default Volume for your normal listening level, as the Chase will have engaged ’Loudness’ before you want it to, it will make tubby bass as I explained above.

IF too loud, you could put the Chase into one of these manual stereo volume controls, then go to your amp’s main in.

Not audiophile, but it isn’t active, get’s you going.

1. Chase at it’s default volume (unplug, plug it in to get defaults). (on/off does not go to defaults, it retains ’last’ settings).

2. Chase out to intermediate manual volume control

3. Manual volume Control to amp’s Main In.

4. Set manual volume control at your Normal Listening level, leave it alone after that.

5. then use the Chase for Remote Volume, up or down, now getting proper advantage of the automatic ’loudness’ at low volumes,no loudness at increased volumes, and advantage of it’s remote volume and balance for tracks that benefit a lot from a small balance tweak.

....................................

After you find someone to repair the Luxman’s Volume controls, remove the intermediate volume control.

Then, like me, my fancy eared friends: try as you will, you simply cannot find any difference with that Chase In or Out. It’s S/N 120db is real.

I am flabbergasted each time it makes no difference other than adding all it's features. My preamp's volume works manually, my Cayin has remote volume, I go without the Chase, with the Chase,  

this is a simple remote volume control

Additional advice is appreciated. Just to clarify, when I placed the Chase between my source and connected to the Luxman main-in, the sound was audible from my speakers, but the volume level was very low and could not be adjusted up or down. Everything else on the Chase worked: balance, treble, bass. 

I don't want to use a simple potentiometer for volume adjustment as it would degrade sound quality, and I have learned how amazingly good the 19 year old Luxman amp sounds. When I use my Audio Research Reference 3 preamp or connect the Luxman directly to my PS Audio DirectStream Dac, it makes me wonder if I should look into a newer model Luxman.   

Jerry. You would be better off connecting the Chase between the pre out/main in jacks on the Luxman.

Elliott. I don't doubt your experience with the Chase, it was along time ago that we sold them and I tried it with an Audio Research tube preamp.

I ordered the two CDs you recommended.
