Current - Class A vs Class A/B, various wattages

Hi Ralph, looks like you have a life mission to educate us so-called audiophiles about Rule 1 of Hi-Fi: amop/speaker matching. Mesaboogie, Ralph (Atmasphere), Al (Almarg) and I have communicated about this issue a "ba-zillion" times by now.

It's a difficult issue to get one's arms around, but it's critical to get it right, or at least not get it wrong, if you plan to dump big bucks into a rig. If you follow my threads over the last 6 months, you'll see that I've been on my own personal mission to understand this concept. I think I may have finally figured out why my amp and speaker combo seems to work well, even though on paper it shouldn't.

Too complicated to explain here, but Ralph is 100% right that if one is interested in buying speakers or an amp, the first Q to get out of the way is whether the combo you have in mind is compatible. This may require separate calls to the amp and speaker manufacturers, as Ralph suggested. Otherwise, after dropping a lot of time and money into buying components, you may have a bad day when you bring it all home and set it up. The gear may not sound like it did at the dealer.

Btw, right now there is a thread running now about a chap who is having major aggravation getting his Music Fidelity amp to work on his PSB speakers. A lot of folks have dropped posts trying to help the member out. It may turn out the problem is a bad amp and speaker match. Jury's still out.

Cheers,

BIF

P.S. I have another great article for lay folks like me that does a great job of explaining what is meant by a tube friendly speaker. I'll post it later today or over the weekend.

well my friend who got me into moving passed a high end consumer system was using some Gallo speakers. and I have really liked them so I ended up buying a pair of 3.1s. he was using a class D amp and I had intended to go tube from the start...but now all I read is how the load varies in then and 200 watt solid state is about the only option for not losing the bass. which means I might end up with very expensive pair of mono blocks that I wasn't ready for. $5k or so was what I was hoping be stay around, but 200 watt tube is more like $10k entry fee....and those don't do the power doubling even then.

Would anyone know if the Gallo 3.1 be considered a "voltage driven" speaker based on Ralphs link?

Mesaboogie: Call the factory and ask what type of amp they recommend. I would also ask the factory a reality check Q about the type of amp the designers had in mind when they voiced the speaker.

I would also search the web to see if Stereophile or HT published any bench test results on the Gallos. If the impedance curves are all over the place and there are low frequency negative (capacitive) phase angles, I would surmise that the Gallos are NOT tube friendly.

Here's the other article I mentioned above about tube friendly amps:
