You are correct. When you can buy a second hand AI or EA for $500 or less but you can buy a used car for the ever increasing price of a WW, it isn't even close.....
We all agree that Walters products sound great, but the discussion is getting pretty far away for a working musician to consider one, especially when you add the price and the unreliable grumpy old man with six month warranty / repair problems. Compare that to a two day turnaround at AI....
Actually, what has happened, as I've watched, over the last 10 years is that Walter's amps, depending on the model, have fluctuated up and down a great deal. Grumpy man and warranty aside, (which by the way, is lifetime. for the Electroacoustic's on the power section, to the original owner ) the biggest
issue is getting them repaired, however his amps are excellent builds, so they tend not to have all that many service problems, unless you have water accidentally drip through the vent holes in the top, like I did. Newer builds like the EA and AI use off the shelf power amplifiers, that can be easily replaced
provided that's built into the design. There are many lower priced Class D amps that are very difficult to repair, and essentially throw aways, if something fails, in their power sections. Personally, when one of my older Walter Woods amps needed repair Walter always treated me fairly and got back to me
in a very timely manner. That said, Acoustic Image has outstanding customer support and service as does Euphonic Audio. I've just owned my Woods Electroacoustic Ultra for longer than AI or EA were on the market. Just my take.
P.S. Their are a lot of sellers that think their particular Walter Woods is the golden goose and
ask ridiculous prices online for them. Many times, they are never sold, Reverb often
has "sale ended" vs sold for a Woods amplifier. It happens a lot more than you'd expect.
