Hey AJ, - personally, I would look at other cartridges. I know Rega is giving you a good deal by combining them, but look at it this way: does anyone ever buy a Rega cartridge for a non-Rega turntable? Probably not. How 'bout the arms? You bet - plus they OEM them for other tables as well.
The Sound Organisation (Rega US distributor) has the P10/Alpheta 3 shown for $7700. If you can get it for $6695, that sounds like a deal - only $1000 for the cartridge. Logically, it should be $6995. $4395 for the P8 combo is charging $1300 for the cartridge.
I love my Sutherland Insight, but maybe the Rega Aria Phono stage is worth considering for $1500 if you're getting the Alpheta 3. I've heard some good things about it, and I am sure it is perfectly set for the Alpheta. Sutherland 20/20 is supposedly great, but I bought a used Insight for $875 and Ron Sutherland (great guy) sent me the linear power supply upgrade package for the $350 upgrade price (I installed it and he said he would do it for free but i would have had to pay back and forth shipping), so it was less than half the price of the 20/20 combo, and it was my first phono stage and I was skeptical about their value. Ask your stereo guy what he thinks about the Aria. I hate to take business away from Ron, but I think it is worth considering. I think I saw a used Aria for $1000 on Audiogon when I was searching for the Insight.
Sorry for muddying the waters, but I wonder if the guy will let you try the P10 also so you can see if it the difference is worth it to you. I am sure it sounds better. When I got the P8's arm, the home listening was what sold me. I wasn't given it as a trial, but was told I could return it if I didn't like it. With my maneuvering I was able to be all in for the complete analogue rig for under $5K (P8/Insight wLPS/Van den hul One Special). With your P10/2020 combo, you're looking at almost double. Maybe it's worth it...but it would be about what I spent on my entire system.
Depends how much you want to jump around to save some cash. I think I've bought one or two components from every high end dealer in my area that is knowledgeable, some new, some used. If you can get a dealer to sell you something used he can attest to, and it is reasonably priced, that is the best of both worlds. Don't let the dealer intimidate you into overpaying or overbuying or feeling guilty about not buying a high enough level product. Remember - there is ALWAYS something better out there. Sometimes these guys act like they're doing you a favor by selling you exclusive pieces. These days there is no such thing as exclusivity. Everyone is hungry for business. My go to guy will give me 15% off at a minimum. (He is not a Rega dealer - doesn't want to carry their entire line).
I am a big Rega fan and don't know too much about Direct Drive tables other than my experience I mentioned in an earlier post with the Phase Linear 8000 which has many motors and sounds nothing like a clean belt drive turntable. Even the $500 Music Hall sounded way better. But like all debates, I don't think it is about the technology, it is about the execution of the individual product/model. I am sure there are great sounding direct drive tables, I just don't know anyone who has one or recommends them other than these guys on Audiogon saying to buy a 30+ year old one.
Hey Chakster - you may be correct about the speed of belt drive tables in general if their power supplies are not great, but on all Rega's mid tables and above, the speed is fine with external PSUs. I have an app that measures it - right on the money for 33 1/3 and 45 rpm speeds.
