Rocket,
Hello nice to meet you!
The whole idea for recommendations from the start of the thread was and still is to identify those cd's that are really great, and really have good sound quality. Demo quality etc.
I too like many of us have purchased many 'dud' cd's...that just have poor recording, sound dull and lack lustre etc..
For the most part most of the cd's that have been identified in this thread are of demo quality...but please be aware many of them may not be your personal musical taste. I have said in many posts that the content may not be ' my cup of tea' or ' i am not a fan of country music' etc...but none the less this recording is exceptional etc.
To set a standard and apply a number etc would be hard to do ..but comments from posters on the sound quality is always welcome.
Take a look at the first thread and the links to the lists, you can see many recommendations and go back and read the comments etc, many of which speak to the sound qualitiy or certain selections on the cd that someone considers exceptional.
If you purchased the cd's listed in these links I would say most of them are really great sound quality, and they would make a wonderful start of a great collection.
All the best
Alex
