Multichannel Class D amplifier for multi-room sound
Thanks spatialking.  Good suggestion.  The Russound puts around 50wpc into 8 ohms and 80wpc into 4 ohms (one zone driven) and that seems to be plenty.  It costs $1000 to cover 8 pairs of speakers.  We need to cover 6 pairs.  Suggestions?

Folkfreak and LewM. Thanks! You guys rock!

@lewm That is the rub!  The company is no longer in business.  I guess I need a contact in the German audio industry to track down the manufacturer - no luck googling thus far.  I will operate within normal ranges.  The pivot to stylus distance ca...

@lewm Thank you! I think I’ll sell my TTB on ebay! I was just going online to purchase a Feickert when I saw your post coming in! Paid the extra $$ for 2-day delivery so I can get this thing wrapped up over the weekend.Just checked the retail pric...

@mulveling Thanks for the suggestion.  I will get a Geo-Disk.  The SMART-Tractor is way too expensive for me.  But I still want to make sure I can achieve 2-point alignment as well.

@wlutke I get what you are saying:  As the stylus traces the flatter arc, the stylus tracing angle changes less in relation to the grooves. The Mint inner and outer null alignment lines will be more near parallel to each other to compensate. Over...

@lewm Sorry I missed your post at 8:05am before writing the one above.  I will need to see if the stylus follows the arc on my MINT - but it probably won't, because I'm using a 10" tonearm and the MINT was set up for a 12" tonearm.  The arc HAS to...

@lewm Is this to suggest that a dedicated protractor is needed for every possible effective length?  See my post above.  If that is the case, the TTB would be misleading.  Must have something to do with pointing the orientation line on the TTB to ...

@wlutke I get what you are saying, and agree that the arc should be flatter for a larger P2S (or a longer effective length).  However, if the null points are the same for both configurations, perhaps this doesn't matter.  By definition, the null p...

@lewm One thing that is unique about this tonearm is that I can change the P2S over a wide range without moving the mount, as the arm that leads to the pivot swings. This can be seen on the link in my first post. Thus I can change the P2S from 230...

@lewm  - I’m surprised at how inaccurate the TTB is. I tried multiple P2S values and I couldn’t get close for any of them. After lining up the outer null point, the inner null point was always at least a centimeter off. @wlutke - are you saying th...

@wlutke The MINT was made for a 12-inch tonearm that has a P2S of 290mm.  Is it possible that a 12"/290mm combination has the exact same null points as a 10"/250mm combination?  I haven't yet achieved a perfect alignment with the MINT and the 10" ...

PS - even though the tonearm is 10", if the effective length is 265mm (10.8"), perhaps it is not surprising that the PTS length that works is 250mm.  When I google PTS lengths for other 10" tonearms (not many hits) I see values ranging from around... 
Mono Cartridge Recommendations
@folkfreak Thank you for that info.  I do you have A mono switch, made by KAB, and it is well-made, but it is outboard and requires more RCA connections to place in the circuit. I was concerned about loss of dynamics. One Miyajima dealer told me t... 
Mono Cartridge Recommendations
@Clearthink - What's with your tone?  Is there any reason to be anything but helpful here?  You quoted me a little out of context.  I said that "many" mono cartridges have low compliance, not all.  Particularly not stereo adopted mono cartridges. ...
