Recommendation Request for Tube Power Amplifier
@ghdprentice Thanks. I am certainly considering used amps. I've seen a used Rogue 100 here on Audiogon that seems to fit. So far, I've seen great reviews, especially from 10 Audio. I should add that I'm thinking that this amp will be for my phono...

@rauliruegas I apologize.

@rauliruegas I appreciate your willingness to continue this discussion. However, I have learned much more than I needed from this conversation. I don't regret any of the comments made on this forum. For me however, the need for exchange of ideas ...

@rauliruegas @mijostyn  Dolby is mass entertainment, not traditional music. I may be a :"wonderful" "immersive" experience, but it is not music. This discussion has veered way off topic. Probably time to cap it off. Thanks to everyone for contr...

@mijostyn I agree.Electronically shaped and amplified music at concerts is highly processed. It can sound really good or horrible depending on how it is set up. A home system should be able to beat an electronically amplified live concert easily. ...

@rauliruegas  I would like to understand what type of studies have been made before I make the effort to design and perform the tests needed. Since my last post I have been searching. I have found one (links below) that seems to be quite thorough... 
A Few Turntable Measurements using the RPM Android App
Is there any scientific data that indicates how a person with "normal" listening abilities perceives audio distortions? What are the lower limits or perception? Is there an emotional reaction to different frequencies? The commonly accepted sating... 
Should I buy a VPI SCOUTMASTER. I OWN 25 RECORDS.
@inorganic For me, there's more to playing records than the music. I happen to enjoy the inconvenience of having to store, clean, and cue an LP. Lots of cartridge, tables and tonearm offerings to drool over. I love the plethora of accessories avai... 
A Few Turntable Measurements using the RPM Android App
I thought about starting a new thread, but the conversation on this one is a good intro into my next question.   "How does one choose between belt drive (including string, fishing line etc...), direct drive and idler drive?"   There seems to b...

@rauliruegas Thanks for the links. Great reading material. Seems like companies use whatever measurement protocol they feel is appropriate. This is very similar to the "alphabet soup" of specs that exist in the Optics and Electronics engineering w...

@terry9 Thank you very much! And thank you for joining in. I'm having fun learning how other real users think about audio and audio gear. I can't get that here in this countryside location. Thanks to everyone else also.

@mijostyn I use REW for room characterization. It is freeware. The functions appear similar.  
A Few Turntable Measurements using the RPM Android App
@terry9 There is a well-defined method for measuring wow and flutter and rumble, which only differ in frequency and source, but not in nature. This method turns out to be quite complicated. Whether the RPM app developer used this method or not is ... 
A Few Turntable Measurements using the RPM Android App
@rauliruegas Hi, Thanks for the link. Surprisingly, the wow and flutter reported for the Double X by the author of the article you referenced is the same as the wow value I reported above for the AS WOW XXL using the RPM app. This result is encour... 
A Few Turntable Measurements using the RPM Android App
@brev Yah, it is fun making these measurements. I wish that the developer would publish his/her methodology. For example, what algorithm is used for the WOW calculation? Is it one of the standards? I don't think we'll find out any time soon. Apps...
