When I decided to change amps the SIT-1's (or new SIT-3) were on my short list. I, too, was hesitant to go with tube monoblocks as I have a small child and did not want to deal with the typical tube concerns (heat, short life, biasing, etc.). However, I got the chance to hear the Linear Tube Audio "Ultralinear" amp and was awestruck by the sound. Also, the amp is a unique design that promises extended tube life (10K hours+) and produce very little heat (much less that your class- A SIT-1s). You may not be interested in changing amps at this point but thought I would mention the LTA's, which are very special. I ran my Ultralinear with Daedalus speakers and the match is ideal. I've go new Daedalus Apollo's on order and am confident that this is going to be a great pairing. Next step is to add another Ultraliner and run them as monoblocks--should be fun.
Speakers for First Watt SIT-1 amp
My favorite sound seems to come from an SET amp and single-driver speakers but I want to leave the amp on all the time and I have kids in the house so I decided to exclude output tubes. I went on a hunt for a solid state amp with an SET sound and landed on the First Watt SIT-1 monoblocks which I love. I'm using them with Omega Super Alnico High Output monitors and it's a great combo but I wonder how much better speakers like this can get with this amp. I have my eye on Voxativ, Teresonic, Audience, and maybe Audio Note or Daedalus. Any suggestions?
