I have ML Prodigy's and am running them with a ARC VT-200. I found the sound to be much more impactful and extended at the frequency extreems going into the 8 ohm taps. The 4 ohms give me a more laid back softer sound (which is nice too). I usually use the the 8 Ohm but I have questioned whether I might be putting a strain on my amp. Guess somebody ought to call ARC.
Which taps 8 or 4 ohm for electrostats?
Hi Everyone,
I have a pair of Martin Logan Ascents which are nominal 4 ohms, dipping to 1.2 ohms at 20kHz. I am using the 4 ohm taps on my ARC VT100.
Someone mentioned that these types of speakers tend to look capacitive in nature to the amp, and have greatly varying impedance values. If they are indeed capacitive, it would seem to reason that most of the fundamental notes would be in an area of possibly greater impedance.
Has anyone tried this combination of amp with stats using the 8 ohm tap? Would this be "harder" on the amp (tubes)? I am not to concerned about the 1.2 ohm at 20 KHz, as I can not imagine there is much at that frequency other than over tones.
Any thoughts would be appreciated.
Ron
