| My first Tube Amplifier http://www.jadis-electronics.com/photos/ja500/45/3/ja500.jpg Do folks know that this amplifier has a slew rate so low that it can only product a few watts above 10 Khz? The power drop off starts around a few Khz and just keeps falling. Now wha... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Ramtubes, could be my terminology is off, but if a loudspeaker has a built in power amp for the bass drivers and separate inputs for an external amp to drive the midrange/treble, then it requires bi-amping. We really shouldnt have to be doing ... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker @ramtubes, Impedance minimum for top section of Aeris is only 3.8 Ohm (this information is from the source). So it seems AHB2 is fine with that.Which amplifier would you think can be a better option than Benchmark AHB2 given that I have gotten mys... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker The OP has Legacy Aeris loudspeakers (a design that requires bi-amping) which according to at least one Legacy dealer really likes high power amps. The OP wants to know if the Benchmarks in bridged/mono mode will have trouble driving the Aeris.... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker @geek101 Thanks, its been fun. My well considered advice:ONE AMP PER SPEAKER, BI WIRED, BI AMPED. Bridged, no, no, no | |
| How good is the McIntosh MC-2300 vs modern SS amplifiers? Well EXCUSE ME (Steve Martin). I guess its too much to ask to clean the pots of a 40 year old amplifier. FYI dirty pots can cause lots of contact (diode) distortion. You must have some very nice looking MIG welders. how do they sound?How impartial... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker @tobes It’s a sealed cabinet design and bass rolls off slowly providing pleasing extension into the mid 40’s in room. Obviously 380W is not required (or used by me) but 150-200W is useful with the low sensitivity SCM19’s if one wishes to explore ... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker As usual, some of us try to help the OP and some of us go off on a tangent to defend their own stuff. Then everyone gets mad, I'm not mad though I am surprised at some of the responses. :(I was surprised to see that the ATC 19 is actually 19 liter... | |
| Anyone used these audio ceramic slow blow fuses from Littlefuse? I don't personally see how a fuse can make a difference knowing what I know about what is on either side of it. However many people are willing to support the foolishness of premium fuses and fund the snake oil salesmen. One was a used car salesma... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker Ok, Im really getting into this amp now. Have a look at this white paper, its good, and the amplifier construction, ugh.https://benchmarkmedia.com/blogs/application_notes/14680625-the-ahb2-a-radical-approach-to-audio-pow...I fix rare amps like the... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker @tobes Why are you amazed Roger?Some of us own low efficiency 8 ohm nominal speakers - for which the bridged mono AHB2’s are perfect. Honestly, Benchmark appears to be one of the least marketing oriented companies around. They don’t push BS, the... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker I don't understand it. 40V across 1 ohm (or 40amps thru 1 ohm) would make 1600W. Kijanki,Thank you. I am glad someone is paying attention.. You are correct it would make 1600 watts. My bad. I appreciate your bringing up the speaker resistive ... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker @georgeI imagine in the 4 ohm bridged mode the current limiting would become apparent. JA is often kind by omission. I think the amp would shut down with a 4 ohm bridged load. Thats like 2 ohms per channel as you well know. I am just amazed at how... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker @tobes With all due respect George, it's not a matter of believing what I want.Implying higher distortion in bridged mode for the AHB2 is incorrect.This has been independently verified.Not sure why you keep insisting on this?https://www.stereoph... | |
| Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker I presume you mean current compared to power output not physical size? The AHB2 is very small and lightweight. IMO the power/current output - not to mention almost non-existent distortion, super high SNR, efficiency, cool running and (most importa... |
