16K to Spend. Help me make the end all Upgrade.

The only reason to get rid of an X350 is to get an X350.5.

I don't think I'm going to go with a ClassA amp again. They run really hot. The sound is great but I'll try something new. I'm going to audition a Spectron Musician III one of these days and see what they sound like.

How about these Tannoys TD12 at have of your budget
OR
these should pass the WAF with ease

Cheers

and this amp - used or almost new goes for around 10K
Tannoys new or open box - around 6K.
Wonderful system......good looking too.

I think the Merlin VSM-MXe have a very high WAF, are smallish so they don't dominate a room, and are perfectly suited to a room your size. While it is down 2db at 33Hz, that seems to be a good amount of bass for a room your size, with the a great high end with the Dynaudio Esotar D330A tweeter. It is an elegant two-way that is pretty hard to beat in my book - and a lot less than 16K. It is also easy to drive and will sound fantastic with a high quality 30-50 watt tube amp, but they work great (and plenty loud) with the Pass XA-30.5 if you want to stick with SS - it is Class A, but runs a lot cooler than the Aleph did. It can be hard to think of a small two-driver speaker as an end-all speaker, but the Merlins is a very well sorted out speaker; worth a listen.

Incidentally, in the Bound for Sound review of the Merlin by Martin DeWulf where he said "'My review of the original VSM was published in 1995; it was a good speaker. But, there was no way of knowing that over the next 12 years, Bobby would refine, build upon and essentially perfect that speaker until it reached a prominence where with some confidence I can call it "the best loudspeaker ever made."' the amp he was using for the review was the Pass X350.5. I get nervous about any claims that anything is "the best", but it is a speaker that has kept me happy a long time and I'm unlikely to change (you'll hear that from a lot of Merlin owners).
