Update: (Pasting the post I made in another thread to have continuity here..)
I did a A-B-C-D comparison between Monitor audio RX8 (highest in silver series), GS20, GS60 and Thiel CS1.6. It went on for 4 hours. Rx8 had to be removed from the equation in the first 5 minutes. No comparison. RX2 is full of bass and nothing else (demoed another day). It is lower in the food chain than Rx6 and Rx8.
Between GS20 and GS60, I dont think there is much of a difference to claim 1.5 times price. Can't make out the difference for any indian songs. Songs with excellent soundstage and scale sounded better in GS60. The soundstage better and overall was little bit better. Anyone could fail a blind test though.
The thiels sounded unexciting for the first half hour. They have lesser bass extension and HF extendion too and a very good midrange and are butter smooth. The more I heard the thiels though they sounded better with a wide range of songs. Very natural. After the second hour and into the third hour, I actually thought I liked the thiels better.
In short, the golds sound excited and luxurious in HF. Imaging is not as good as the thiels and they have higher bass extension. Sometimes throws out bass 'blobs' in comparison to thiel. HF is definetely better and well controlled to the extent they sounded sweet.
Thiels have lesser bass extension, super silky midrange, stronger and leaner highs and not a single song sounds bad in it. Only issue is very very good recordings do not sound as exciting as MAs in the thiels. karnatic songs sounded 'special' in the thiels though. Most voice centric songs also were very very good.
So still undecided between GS20 and CS1.6. Confirmed that the advance paid can be used for either of them when I decide.
Amp used was Musical Fidelity A5.5 and DAC was Musical fidelity M1 DAC.
