Please do not recommend source material because you heard them in iball speakers and liked it. I almost fell for it and made an online purchase. Good thing I delayed it. G0bble
The Classic Revival is good. Unfortunately, it is not available in the market anymore. I have nearly 90% of the CDs released, and am looking at ways of getting the rest.
One of the best options I have seen is to go to hamaracd.com, make a CD there, and get it delivered to your home. Does not cost much, and the quality is reasonably good.
Sometime in the near future, I plan to create a thread that has spectrum analyses of some of the CDs released in India. I even took a few DVDs, ripped the music, and checked their quality.
The worst was YRF DVDs (that come in a Blu-ray kind of cover but red in color). When I ripped one of the songs and checked it's quality, a song from Veer-Zara has been completely chopped off flat at 10kHz. I checked a few other songs, and there were all the same. Shocking.
Songs from Classic Revival have a decent bandwidth, some peaking at 22kHz. But, the bulk of the songs are below between 10-15kHz.
I found modern recordings to be good. The CD of Bang Bang is really good with a large part of music fluctuating between 15-22kHz. If I remember right, Bang Bang is released by Sony.
Another set of CDs I liked is titled 'It is Rocking xxxx' where xxxx stands for the year. I have 2011, 2012, and 2013. Released by T-Series, the songs have been well recorded and presented.
I think pre-80 songs have an issue with their master itself. Someone at Saregama has screwed big time when transferring all the music to a digital database. If my suspicion is right, I believe all those songs are lost in terms of recording quality.
If some one knows where I can buy Classic Revival CDs, I would be glad to hear from him/her.
Cheers
