Hello im new to this forum and need some much needed help from people who own a Meridian product not someone trying to sell me one. Is there a sonic differance between the 2 units,is there a slight differance a big differance, can I connect my I170 iPod transport to it, will the g68 work better with the wadia or should i use a DAC then connect it to the g68. Is there a sonic differance between the g68d or the g68adx and so on. Thanks in advance for taking the time to respond.
