Hello,
I'm sorry if I already posted this. I couldn't find it on the forum
I live in the US in New Jersey, and don't speak your language. I know at least some of the posters on this forum speak English, and I was hoping someone could help me with an Electrocompaniet purchase decision.
Luckily the registration process for this forum is similar to most others with which I I'm familiar so I was able to work my way through without knowing the language.
Following is some background. My question is at the end.
My current system consists of the following components:
1. EC EMC 1 UP, which is the current 24 Bit upsampler 192KHz DAC
2. Parasound Halo P3 balanced preamp. (soon to be upgraded)
3. EC AW70 70 watts per channel in stereo mode
4. NBS Serpent III balanced audio cables and speaker cables.
5. Magnepan (Magneplaner) MG1.6 QR.
6. AR turntable and Linn Basik LVX arm and Ortophon high output moving coil cartridge.
The MG1.6 QRs are 4 Ohm speakers. Tests by the US publication 'Stereophile' indicates that the lowest resistance for this speaker is 4.5 Ohms.
I don't know how available or popular Maggies are in Europe, but for those not familiar with them, Magneplanars are large planar magnetic panel speakers with a sheet of mylar stretched over a magnetic network. The speakers also contains what is referred to as a quasi ribbon which handles frequencies above 600 hz. This is a highly regarded two way speaker over here and is relatively inexpensive at around $1800 US.
The Electrocompanient seems to be a very nice sounding amp, but only puts out 70 watts at 8 ohms and 120 watts at 4 ohms. The Maggies are VERY inefficent. 1 watt only produces around 83 db at 1 metre. As you can imagine, its easily to run out of power with a 70 watt amp, especially on classical recordings with a wide dyamic range.
The AW70, which according to the US distributor is renamed but identical in all respects to the AW220, can also run in mono mode and produce 220 watts. The US distributor Jason Scott Inc has a demo AW220 which they are willing to sell me through my dealer at a very attractive price with a full EC warranty! The review of a pair of AW220 (AW70) amps received a rave review in 2003 from the English language online high end website Stereo Times.
Finally my question ???. When a pair of AW220s (or AW70s) are used as monoblocks does the output impedence fall too low to be used with a 4 ohm speaker like the Maggies. The EC manual for my AW70 raised my concerns regarding this question.
The distibutor indicated that while they couldn't be certain, they believed the combination would work, although the amps might run hotter. They indicated they were sending an email to the factory in Norway to get their opinion.
Any feedback on this combination with regard to the impedance question, or any other opinions would be welcomed.
Thank you
Mark
