JM Reynaud Trente to GMA Callisto or Merlin TSMMe?

Yo2,
One lesson I have learned, if you are happy with your current speakers dont sell them until you have another pair in your house you prefer. I had a guy trade me his JMR Offrandes for my Merlin VSM Milleniums I thought the Offrandes destroyed the Merlins he prefered the Merlins.

About 5 years ago I traded JMR Offrandes for GMA Continuum 1.5 i speakers. Overall I think it was a good move. The Offrandes were a little on the piercing side sometimes, but were really precise. Both speakers continued to get better for several months after installation even though they were used. It might be tough to make a decent comparison of speakers that are a good fit in your system since you probably can't try speakers out for six months a pop. Alot of times one night shoot outs are pretty useless. You could try moving up the JMR line if your room and components are suitable, or you could (hopefully) have some fun trying different things. Going nuts and not having alot of fun is a commonly chosen option.

The GMA is a step up and the Merlin a step down IMO.

Trust your ears and don't be in a hurry to spend your children's inheritance.
