I am looking to purchase a Harman XXV, and I was looking to see if Harman has put any of their prototype design updates into production yet or if they are still in the process of monitoring their prototypes before they make a final decision. I know PJPellet had gotten a new prototype burn pot from Harman to test out to see if it eliminated his subwoofer / woofing sounds, and I know bcb1 had gotten a new auger motor installed to see if it corrected his whistling / squealing / grinding noises, but I have not heard if these corrections have been a success and finally put into the production models, or if Harman is still trying to work out the bugs. Also, any news on if Harman was able to produce an ignitor that lasts longer then say 2 years? Most everyone I have heard from has had to replace about 3 ignitors within a 6 year time frame. If I were to purchase an XXV today, are all the parts the same as say an XXV that was produced and sold in 2005? If not, what differences are in todays production run then a production run back in 2005? I really like the XXV, but I can wait another year or two if need be until they correct their issues before making this purchase. If all of the bugs are worked out now, then I can make the purchase today. I just figured there is no need to rush into this and have the same issues as I have seen here on the forum if there are still problems with the design of the XXV. But once all of the problems are corrected and put into production, then it makes sense to me to move forward with this purchase. Thanks!
