A few days back, i was using Acrolink and Oyaide cables on my system: Oyaide on my amp and Acrolink on my Duet and CEC. Also, Acrolink A2400 IC from my CDP to Amp and Oyaide Across750 IC as jumpers on my amp. The tonality is very good except for a slight glare that i attribute to the Oyaide IC.
My Acrolink 4030 is terminated with Oyaide 004 plugs. I have compared with the 046 plugs prior to purchase. The former is simply more neutral and refined.
People say that the Acrolink 4030 is bass-shy. I agree with that to a certain extent. The bass is still there, only that the mids and highs seem to be of more prominence such that it gives the illusion of the cable being bass shy. In fact, the bass is very defined! Try pushing the volume up and you will get what i mean ;)
There is a way to bring back this balance. The solution will not come cheap though. You will need to get the Acrolink 6N-A2400 IC. This IC will give the system a fullness to the bottom so that vocals will sound more realistic and the dynamics in the music will be very evident so that you will no longer feel that the instruments take second seat compared to the vocals.
The Acrolink combination of power cord and IC will beat that of the Oyaide combination hands-down in terms of definition and staging. Side-by-side, the Oyaide combi sounds muddled and the vocals are a bit harsh especially when the singer goes for the high notes compared to the Acrolink combi.
Currently, i am trying out the 4030 with 004 each on my amp, cdp and duet. Vocals are very clean and airy. Cymbals and high hats have a delicate ting and sizzle that i have not experienced in my setup before. Very appealing indeed! However, the problem of the prominence of the bass taking back seat surfaces again...sigh...hee :D
