Hi Mac, The advantages of using the PCM1748KE dac are: -- 6dB improved SNR -- 6dB improved Dynamic Range -- Improved THD and channel separation specs (I don't remember the figures off the top of my head). Whether or not you will hear the improvement depends on your system, hearing, etc. I trust my ears and my customers really like what they hear from their modded squeezeboxes, so that is all that counts to me. Regarding the Toshiba 3390, I am not familiar with this model (do you mean, 3950, 3960, 3980?). Have you even heard one of these that I myself have modded, or was it a stock unit? If it was a stock unit and you were disappointed in it, this has nothing to do with me or my Squeezebox mods. If it was modded by someone else, there is no way of determining if the mods were made correctly, if the soldering quality was good, etc. Regardless, this has nothing to do with my Squeezebox mods... As far as converting to battery power, your statement that properly engineered AC power is far better is simply false. What type of batteries did you experiment with? How did you implement the conversion? Did you even hear a battery modded Squeezebox that I offer? Again, how can you make such general statements? They provide us with very little value and lead to confusion. I have received feedback from MANY satisfied modded Squeezebox customers who would beg to differ on your comments, especially since you haven't even heard any of my work (or have you?). Here are just a few examples: http://www.redwineaudio.com/SB2_Testimonials.html Search on the Red Wine Audio forum on www.audiocircle.com if you would like a lot more feedback on my work. I hope you understand where I am coming from and do not view this as an attack. That is the farthest from my intentions. Thanks, Mac. -- Vinnie R.
