Hawkeye Posted December 13, 2020 Share Posted December 13, 2020 Would a Nad C375BEE be a better suitor for my Gale 401's ? Using my Marantz sr7008 125 wpc theatre amp doing a reasonable job. Thoughts please. Link to comment Share on other sites More sharing options...

stereo coffee Posted December 13, 2020 Share Posted December 13, 2020 The issue with driving Gales is their low impedance, typically 3.7 ohms. Your NAD integrated amp specifications here: https://www.hifiengine.com/manual_library/nad/c375bee.shtml Reveal the NAD's output power does not change relative to 4 ohm or 8 ohm speakers, most amplifiers will double their given rated power when the loudspeaker impedance halves, which infers it is very likely the NAD has insufficient current to properly drive the Gales. Certainly try the NAD, but being also a owner, the Gales deserve the best, least clutter attenuation, and solid state power amp you can afford. 1 Link to comment Share on other sites More sharing options...
muon* Posted December 14, 2020 Share Posted December 14, 2020 (edited) Works into low impedance loads. Pair it with a decent suitable preamp. Edit: mind you, the pre amp needs to have a very low output impedance to drive the ME amp properly, according to old member ZB (Trevor) less than 10 ohms output impedance. Input impedance for the ME 550 is 1k, so ideally 10 ohms, but a pre amplifier with an output impedance under 100 ohms will work. Of course a ME 25 Pre Amp would have the ideal output impedance for it. Edited December 14, 2020 by muon* 1 Link to comment Share on other sites More sharing options...

Much better to match sensitivity of the power amp to just match the source, rather than appeasing one manufacturers aims so you have to use their preamp with their power amp which IMO is very silly. To match the source to the power amp, use a power amp with specifications like this, you will then hear your source component without any alteration / reactance in between, which encourages using simple resistive attenuation. 1 Link to comment Share on other sites More sharing options...
stereo coffee Posted December 14, 2020 Share Posted December 14, 2020 I should add the 306 is under- powered for Gale 401, but almost identical circuit the 909 gets closer to what the Gale needs. 1 Link to comment Share on other sites More sharing options...
Paul R Posted December 14, 2020 Share Posted December 14, 2020 Too much power is not the issue. It is the quality. Try the Elektra Reference HD as a power amplifier. You may get one on the second hand market at a good price. I use one. Bought it new, no regrets. 600 watts into 4 ohms. Get a Proton integrated amp fir use as the preamp. You won't be disappointed. I'm running a Doge 8 Clarity 2017, no regrets. 2 Link to comment Share on other sites More sharing options...

Not sure why they've quoted the RMS output power that way. It piqued my interest so I had a look at the service manual. The dynamic power specs there suggest 64% more power at 4 Ohms, and that the amp is capable of driving a 2 ohm load in stereo mode. Specs also show Damping factor of >200. The 2 ohm capability and the high damping factor will be due, in part, to having 4 devices in parallel in the output stage. So I can't see any reason why the NAD wouldn't have more than adequate power for your Gales.

Wimbo Posted December 14, 2020 Share Posted December 14, 2020 @Hawkeye The NAD's not a good enough amp to drive the 401's properly. The 401's have been described as Quads with Grunt. So, they can be very revealing. Talk to Mark Houston about getting one of his Pre/Power combo's. Does the trick brilliantly for me. 2 Link to comment Share on other sites More sharing options...

muon* Posted December 14, 2020 Share Posted December 14, 2020 (edited) Not all NADs are created equal Edit: just to add, we can be pleased with something....until we hear better You want something with lots of muscle with the 401's, so heaps of current available on tap and stable into low ohms. Amps (amperage) are what is needed more than lots of watts, reasonable wattage but lots of current, having both is not a bad thing though. Also, one that sounds good to you.

Thoughts please. ... you are already using an amp rated at over double your friend's - and yet you feel your Gales could sound better. Sounds to me your friend is a "sounds OK " type of guy ... whereas you are someone who seeks 'better'. (Similarly - in terms of wine, say - there are lots of people who are quite happy drinking 'goonbag' wine ... who don't 'waste' money buying wine in glass bottles.

Ooogh Posted December 15, 2020 Share Posted December 15, 2020 Firstly congratulations on choosing one of the greatest speakers ever produced. Although the ‘C’s are not the design icon that the ‘A’s are in our experience they are superior sounding, due to the chrome caps not covering half the woofers and far easier to work on. As others have stated you need power and current and LOTS of it. Bryston is the best match we have found. You might find a very old 4BST in your budget. 300Watts into 8 Ohms, 500 into 4 so they have the required grunt. Beyond that I think given your budget it would be well worth contemplating some pro gear. Cheaper and built to be bludgeoned. Hopefully @Tubularbells might have some suggestions. Don't abandon these speakers till you hear them with some real muscle up them. Our experience has shown you can not judge just how remarkable they are till you hear them with 500+ Watt amps driving them. @Tony M experiences something close to Nirvana every time he plugs them in and he has the choice of numerous far more expensive options.
