Have now been using the USB recovery for 5 days and I can say this is staying in my set up , after 30 min use I could here much more detail the words were much clearer the bass was more defined . Now after 5 days its has improved much more I needed to bring in my speaker about 25mm on the left side as the sound was clearly off to the right and both forward by 30mm the sound now was so sharp , deep and at times the hairs on my arms were standing up it was so different to what I was use to hear before and I am still using the supplied USB cable and wall power adapter so my next plan is to use a better cable and I have already bought a LPS which should be here next week .
I have tried the Regen and this did nothing in my set up so I was a bit unsure if to try the Recovery as they are some what similar in what they do but as it turns out it made a huge difference for me if you have tried the regen and it did not work for you this may be just what you need .
The power input uses the same pin hole as the regen so for those who have a LPS on the regen can use this for the recovery the voltage for the recovery is 9 volts but it will work from 5 volts to 9 volts so if you have options try different volts a different setting may give a better sound .
The Recovery is not expensive for what it does so it becomes a very affordable up-grade but when buying a LPS and better USB cable its pushes up the price but thats all up to you on how much to spend on a cable and LPS because there is so much to choose from and remember the most expensive is not always the best , and using what came with the Recovery still works very well .
