My retailer told me that SimAudio offered to “buy back” my 6+ month old SimAudio 600i V2 integrated amplifier at “full price” in exchange for a new SimAudio 700i V2 Integrated amp.
After a long conversation (with my retailer), I decided to accept his offer. The 700i V2 amp has a much better oversized dual-mono power supply. My retailer said the sound improvement will be very noticeable. I auditioned the 700i V2 amp and liked what I heard using my PMC Twenty5.26 speakers. It was a great opportunity, so I ordered the 700i V2 amplifier.
The 700i V2 amplifier has its own dedicated power supply for the preamplifier, while the 600i shares its power supply with both sections. The 700i V2 amp also features a considerably larger power transformer with greater reserve capacity.
My retailer highly recommends SimAudio products because of their excellent sound quality, solid construction and great customer service. SimAudio offers that for any new SimAudio equipment you bought new, they will credit you 100% of your $$ investment if you purchased the unit in the last 12 months, and 75% in the last 12-24 months. This is how I upgraded to the SimAudio 700i V2 integrated amplifier. I hope this helps.
Out of the box, my new SimAudio 700i V2 amp sounds very good. Now, after break-in, my 700i V2 amp sounds clearer with more musical detail then my previous SimAudio 600i V2 amp.
I have no experience with the SimAudio separates you mentioned but my SimAudio 700i V2 amplifier is outstanding.
