Sleepy, I tend to agree with you on this. iF you have the right equipment, then these improvements are possible. Running my modded SB2 with ext power supply doesn't compare to getting my Anteople Audio Gold dac. We're taking a different universe here. Music can be very enjoyable without having the detailed, expansive soundstage etc. But having those extras makes it much more enjoyable for me.
Overall, I have never enjoyed doing the a/b comparison thing. When I change an item, I put it in the system and listen for a very long time to get the character of the music. Otherwise, I tend to get stressed trying to find a "difference". I've had dealers tell me how obvious some changes are by changing cables, components etc but that short term a/b
stuff doesn't work for me and frankly stresses me out a bit.
Right now, I'm auditioning some digital cables and hope to try 3 to 4 more to make a decision before finalizing my ICs and SCs
