Best sounding op-amp
Agree spec is not always the best gauge. However, I read many postings that majority of them prefer the AD8610/AD8620 over OPA627 from their setup. I'm not sure it has to do with spec or how they setup the Op-amp. I know the decoupling cap choice ... 
Which Counterpoint Preamp SA-5000 or SA- 5.1???
So far we own 5 SA5000s among our audiophile friends and all of them are trouble free and noise free. I do agree that it is a lot more complicated than SA 5.1. We prefer SA5000 over 5.1. 
Best sounding op-amp
The only difference between the AD8620A vs AD8620B is the voltage drift per changing temperature ( 0.8 to 3.5 uV/C vs 0.5 to 1.5 uV/C) If that's critical then it is worth the price. Temperature range from -40C to +125C 
Why do tubed preamps image better than SS?
Anything is possible as long as it comes with price tag. For the $$, majority of tube gear will have better bang for the buck performance over SS 
Are smaller high end speakers really better
Oops typo. I mean to say subject line should be modern speakers vs vintage speakers. If you listen to non revealing speaker then it will put you to sleep because it lacks of excitment. Too much of anything is not good. Your taste and ear need to d... 
Are smaller high end speakers really better
I don't think the subject should rename to modern speakers vs vintage speakers. It is true that more revealing will create more fatigue listening in the long run since your grain need to focus more on the detail. 
Best sounding op-amp
I'm currently using AD8620 on my Marantz 67SE and love it.I also upgraded the clock board too.After done much research, I found the AD8620 has the best spec. 
So, is it Clarity or Brightness?
It's possible to achieve anything when you match everything right. In fact, it is our goal in system building. You really need to know how each component sound (including cables to tubes.) Everything matches by ear and not by class-A. 
Do not use stock jumpers
Any jumper will be the stock. Brass plate doesn't conduct as well. You'll definitely get much better transparency and dyamic sound using any jumper cable. I personally prefer pure silver material. 
Stereophile confirms new gear is getting worse....
Maybe they should stop publish specs and just call it a "black box with spice"?Without the testing euqipment, we'll never know if anything you bought is within the spec.Do you trust the spec over your ears? I don't. 
Jena Labs - Any experience?
Hopper, are you on SS or tubes? 
Tube base preamp suggestions
Counterpoint SA5000. You just missed few rock bottom price deals here on audiogon. It has the most romantic, seductive and addictive sound. 
Which preamp to buy in the 2000.00 range used
If you're looking for balanced tube preamp, Audio Research LS-5 is your best choice 
Best-front ported monitor speakers?
fully sealed might sound better in this case. Ported speakers usually need more breathing room because they're bass reflect type. I definitely recommand used 3/5A type (spendor or rogers will do) and used ATC SCM10 passive. 
Tube Amplifier Rec. for Proac 1.5 or D 15?
I've heard the best performance of Proac 1.5 and 2.5s with Mac MC240. EL84 is definitely under powered. Unless you own a pair of the original Marantz 9, EL34 didn't sound as good as the 6L6GCs.
