The Wild West can be a place of innovation too… there are stories here of pursuit of different options, like trying the Lampizator Baltic by one poster here that was a success for them. I never enjoyed my Amber III much.
On the other hand, when I plugged my Pioneer N70ae streamer into my ARC Ref CD9 to use the quad DAC’s inside it I was shocked. Best upgrade ever. Just using coaxial over rca.
That pioneer spirit is a valuable part of the Wild West and can lead to leaps ahead in enjoyment of your system. Sometimes without spending a penny.
And tweaks? They’re a choice too. I tried Iso Acoustic footers, but my gear is already dampened internally so they made no difference and were promptly sold. Yi ha!
