@stephendunn  All the best on going forward with the Thoress EHT integrated and TotalDac D1 Direct.
Scott Sheaffer’s Found Music custom 2A3 amplifiers went in the system two Thursdays ago. Initial impressions are very positive.

Unfortunately, Hurricane Ida meant having to power off two Saturdays ago. Power is estimated to be back up this coming Wednesday. I should be able to report back with more initial impressions in a week or two.

Our house sustained significant damage from a large uprooted tree which took out one side of our home. This is where the audio room is. I doubt construction and repairs will start anytime soon, but when they do I will have to forego the audio system as we are short three rooms in our home.
Sorry to hear about your house David. Hope everyone is safe and the audio equipments survived the damage.  

Best wishes for a quick and safe recovery

A reminder......the Neo 10 drivers are $6500 the pair directly from the US distributor. You can build an even better box for way cheap. However, if you mounted it on a four foot high by 2 foot wide open baffle....with four foot by one foot wings going straight back on each side......you would have even better sound......and you would still get flat to 40hz bass. You could buy some 13 ply baltic birch three quarter inch plywood and use three layers with green glue in between each layer.....pretty darn dead.

For even better sound (whether in a box or open baffle). You can hardwire some great sounding wire directly to the voice coil wire (the point where the voice coil wire is soldered to the banana jack). Then you solder that wire (either hanging out of the box.....or dangling off the driver in open baffle) directly to your speaker wire......so there would be no speaker connectors what so ever......this will blow your mind. You an also solder a Ground Enhancer directly on the negative voice coil wire, as well for even more info. WAY, WAY more transparent. or you can keep your speaker stock and enjoy the veiled sound.....he he. You can do what I suggest and put it all back to stock later on when you sell the speaker (if ever).

You guys have never heard your speaker......you do the above and you will cry and weep it will be so good.  One of you wants to do it.  One of you is not a sheep.  One of you wants to get sound to die for.....all it takes is one person willing to do it.....costs really nothing to hardwire.......just some labor.....and you can put it all back to stock without anyone ever knowing.  Don't be a wimp.....he he.  You can do it.  I will talk you though it on the phone, if you like....really.  I want you guys to weep with joy over your sound.
