I am planning on buying a audio research ref75se power amp. It is rated at 75watts per channel, do u feel that would be adequate to drive my summits for two channel use and also home theater use? Thanks
Ultimately, the answer depends on how you define adequate.I am planning on buying a audio research ref75se power amp. It is rated at 75watts per channel, do u feel that would be adequate to drive my summits for two channel use and also home theater use? Thanks
A good rule of thumb I've been told is (Tube Amp Wattage) x 3 = Solid State Amp Wattage. Tube Amps produce way more current that SS amps.
Really?!
I think it's quite the contrary, tube amps can have huge voltage swing but somewhat limited continuous current capacity. There may be exceptions but generally tube amps have higher output impedance and this is a parameter which has more effect (positive or negative) to sound quality than current output capacity unless driven to absolute limits.

I would respectfully suggest you try ARC with other related products and listen again. ARC tube equipment mates very well with ML.
I disagree. The low end won't be a problem since the OP is pairing them with Summits, which have a SS amp on the woofers. The ARC will give a beautiful midrange and any roll-off on the high end will probably not be that drastic or detrimental to the sound.
I don´t agree. The impedance match is not a match in heaven.. You will have a rolling-off effect with ARC, maybe with a exception with a the largest tube amps (larger bandwith), but I was thinking of the 75W. Compared to a Gryphon (direct coupled SS) for instance - the differences are huge.
I have myself a rolling off problem with the Macintosh due to the transformers. However, the effect is not that bad compared to some tube-amps.
Of course, I respect anyone that disagrees. However, I think I have the maths on my side. It is difficult to match a ML with an amplifier. The midrange is always best with tubes - but the mismatch in impedance for low and high frequencies (due to the transformer and the varying speaker impedance loads) makes the direct coupled SS always the best match. The problem with SS amps: they sound harsh on very honest ESL speakers - so you need to find a amp between tube and SS. Go figure.. The ARC is best matched with loudspeakers with a stable impedance over the whole frequency area - the very opposite of MLs.
I do love the ARC amps, but not matched with ESL.
