Will Merlins be too much

I had FAR superior amplification to yours when I ventured into Merlin-land. Granted this was years ago and perhaps Merlin has changed the formula but all I can offer is that the "little" Merlins were a very sterile (read "not musical") ride that was not at all to my taste. Others, clearly, dig the Merlin sound. Not my cup of tea. Be very careful with partnering gear. There is a reason the Merlin is shown at shows, primarily, with Joule.

The TSMs sound great in rooms of your size. I've heard current production TSMs sound excellent with moderately priced solid state gear. Haven't heard your Nak. components, but if it isn't a good match, you can get good compatible amp for less than you probably think.
Talk to Bobby@Merlin. You will be amazed at the personal approach he will take to understand your needs & preferences. You will be hard pressed to find another speaker that will give you as much long term satisfaction as the Merlins. Cheers,
Spencer

Lindisfarne comments may be accurate about the old Merlin's, I am not sure. But I can tell you he is "wrong" about the current Merlins. I have the TSM-MX's, in a small 10 by 12'ish room, and they are anything but sterile. Drop Bobby a line, he is very approachable and will let you know about your situation. Just be aware that they are very revealing and will show any weaknesses in a system.

Regards,

lindisfarne, what model tsm did you have?
and how many years ago did you have it.
newer models can be used with a much wider variety of associated gear.
yes there is a reason why joule is used at shows and it is not because it is the antithesis of the merlin sound.
a lot has happened with the newer models.
