…….. but then uncomfortable when we speak of it in absolute terms

Paul McGowan: We’re comfortable suggesting sound is subjective when it comes to our differences in perception, but then uncomfortable when we speak of it in absolute terms.

CONVERSATIONS WITH COLIN: To what extent – if any – can exceptional interconnects compensate for a mediocre CD player?

Dear Colin, An audiophile friend made the following argument to me: “Stop looking for a new CD player. With a very good to excellent high-end interconnect you will not only improve the performance of the CD, but other downstream components.” I had to disagree with my friend claiming a $400 or $500 IC is not […]

Dear Colin, I’ve ordered a pair of 4-Pin DIN plugs to construct an interconnect for a Quad 33/303 system.

AMPLIFIER STRESS: Is this why 4 Ohm loads stress amplifiers?

There have been quite a few questions lately regarding the safety (or otherwise) of driving 4 ohm speakers from amplifiers only rated to drive 8 ohm loads. Rather than just add to the mass of unsubstantiated conflicting opinions (e.g. “amplifier XXX is built like a tank, so it must be able to drive 4 ohm […]

CONVERSATIONS WITH COLIN: Why sell an under-optimized item that can be easily improved upon by the owner or a modder?

Dear Colin, If audiophile grade feet, power cords, and fuses can really improve sound quality, why don’t high end designers/manufacturers just incorporate these audiophile grade components at the time of build? Why sell an under-optimized item that can be easily improved upon by the owner or a modder? I guess you don’t do that at […]
