Upgrade Advice for music lover


Hi, all!
I've narrowed down my choices based mostly on brand loyalty and sound quality for the money, but am interested in the group's feedback.  Looking for answers to which of my options is best and which update adds the most incremental sound quality as I work towards the end.  I listen mostly to jazz, 80s/90s rock, and newer alternative, often loud :) 

Thank you!

Current System:
Linn Sondek Valhalla (1985, recent Cirkus bearing, orig owner)
NAD 3155 (using pre only, recently serviced)
NAD 2200 
Polk Audio RTi8

Anticipated System:
Linn Sondek (TT above, and an upgrade to Lingo 4 $2k)
NAD 165bee or NAD C658
NAD C298 or NAD 275bee
Monitor Audio Silver 8 (used $650) or Paradigm 800F (new $2k)

  • @frank: thanks for all of that good info. I am a little intimidated by tube stuff but will check out those links. Thank you!
You're welcome.

No need to feel intimidated at all. If you are truly a music lover as you stated, then tubes are the way to go. You have a wonderful turntable and it truly deserves tube electronics. 

One of the most musically involving systems I've heard to date consisted of a Linn turntable, a pair of Linn Kan speakers on stands, a modified Dynaco Pas preamp, and a pair of modified Dynaco Mk III mono tube amps. It didn't throw the biggest soundstage, nor did it have the deepest depth, but John Coltrane's sax was right there in the room with us.  It was spellbinding.

Go with tubes, you won't be sorry.

Thanks, @rego.  I guess you are saying an even demand on the amp allows the amp to work at its best?  Thank you.
I agree with the one component/change at a time thing.  I just started the PS upgrade for my tt.  I look forward to that.  I guess then, speakers!
From one music lover to another ...

If it were me, I’d go with tube electronics. Check out the beautifully restored and modified Dynaco Stereo-70s being offered here on A’gon from time to time. I think they are around $1400. I think Frank Van Alstine has a tube preamp at a reasonable price too. Check these out >>>

With that preamp, you'll need a phono stage. Van Alstine can take care of you there too.

Here’s one of Van Alstine’s solid-state amps. I can highly recommend this amp as I owned one for a number of years before getting into ARC gear.

Here’s a nice upgraded Dynaco Stereo 70 that is available on A’gon at the moment. It could be sent to Van Alstine to have his circuits installed.

The SQ will change with Amplification / Pre choices and a good Phase / 
Impedance will help to give a Coherent Presentation, with a well balanced load to drive.
For example an even 8 ohm (Tube Amp using 8 ohm tap) load will let the Amp work exceedingly well.
Someone here may have some input as to the NAD / Silver 8 combo.
Another more general suggestion would be add / subtract one component at a time and evaluate the differences for yourself, so as to not induce multiples of quality and quantity making evaluation more difficult.

 
Loudspeakers first. Your choices are good. Save up your money and make an amp change later, perhaps a little more upscale than NAD. 
The Silver 8 looks like a more even Phase / Impedance vs Frequency plot.
Virtually flat 6ohm ...
