Drummers! Which amps do you use for best Timing & Dynamics?


Many audio systems fail to deliver a really tight groove with correct dynamics and rock solid timing. The timing must be coherent from lows to highs as well. Some amps time well in the mids but lag behind in the bass. The amp must be lush or free of any hardness at the same time as well.

Please share your choices for amps , sources and speakers. 

In my case I am looking for great low volume performance, huge soundstage that opens up in direction to the listener, and the tight groove of course. Speaker efficiency 88db, minimum impedance 3Ohm.

I have the impression that amps which double into 4 ohm, have zero negative feedback and have high idle power consumption are the best for high current low volume performance.

I also prefer single solid core cables for best timing.

Price up to 5k used.

As bang for buck reference I want to mention the Kinki EX M1 integrated or M7 power amp which has excellent low volume performance and timing. It is slightly lean, cool mechanical and I am interested in other alternatives ( neutral or warm)

Be interesting to hear how the GaN amps sound to drummers. I have a highly modified class D based on dual IceEdge AS 1200 modules. At 1200 wpc @ 4ohms it did a really good job of energizing my very large room BUT, I now have a LSA Voyager 350/600 wpc GaN amp which sounds significantly more potent. I wasn't prepared for that. Micro detail and strong drum thwacks, though they could be stronger (mods could help), especially better wire from the modules to the inputs

Actually what you're looking for is the right distortion signature. If the amp has that then the way the amp does it is unimportant. What you're looking for is an amp with a significant 2nd and 3rd harmonic, enough so that the higher orders are masked. This will cause the amp to sound smooth and if the amp is also fairly low in distortion, detailed as well. So you can't see this in the THD figures- you have to see a spectrum of the distortion components.


Also the distortion should be the same at all frequencies. Usually amps are tested for distortion at 100Hz, which isn't high enough to show what's going on. It should have the same THD at 100Hz, 1KHz and 10KHz.


You're probably looking for a solid state amp since your speakers are difficult to drive. You might want to keep in mind that making an amplifier work hard for a living will in all amplifiers cause the amp to make more distortion. Do not be fooled by claims that the difference is 'inaudible' or 'negligible'. It is easily heard as reduced detail and usually harsher and brighter. If you really want to hear what the snare and cymbals are doing, this is an important consideration.


Another issue with inefficient speakers is thermal compression in the voice coils. This is caused by heating of the voice coil with each bass note- it causes the voice coil to become harder to drive and if you simple turn up the volume to try to overcome the dynamic issue this imposes it gets worse. So you might consider getting a speaker that's easier to drive if you really want to hear what the drums are doing.
Wow, great response atmasphere !

The problem is that I have not heard a high efficiency speaker that sounds good. More efficiency usually means more coloration, thinner and unstable sound. Horns do not image well and the sound seems to originate from behind the speakers.

That sounds like a setup problem to me. Horns can image as well as anything else if you use their directivity to your advantage. Early reflections from side walls can be interpreted by the ear as harshness; so with horns you can prevent the side walls having such an influence by reducing the amount of reflection you hear.

I run horns at home and their imaging is pinpoint. Plenty of depth too. I would not association greater efficiency with coloration, but it is true that more efficient speakers can be more revealing: you really want your ducks in a row or else the speakers will show off what's wrong! My speakers are 98dB and go down to 20Hz; they are anything but 'thin' :)  Their first breakup is at 35KHz so they are quite smooth too.

Put another way, there's no downside to having the speakers easy to drive until bass output suffers at efficiencies north of 100dB. At that point you might have to have subs (and subs can be a very viable way to do bass if you have something called a 'Distributed Bass Array'; google 'Audiokinesis Swarm for more on that....).


I'm not saying that a 1960s horn system is the way to go here; as far as that goes there are a lot of speakers from the 1960s that are pretty colored. I'm also not suggesting that you get something that is 105dB or the like; if you can get something that is in the mid 90s for efficiency and also a higher impedance that will mean you need less power to do the same sound pressure. For example, if your speaker is 88dB, and the new speaker is honestly 95dB, you'll need less than 1/4 the power to get the same sound pressure, and if the speaker is properly designed you won't lose any resolution or have any greater coloration- in fact it may sound more detailed and less colored simply on account of the fact that the amp is making less distortion.


Pay attention to impedance too- higher impedance loads on any amplifier result in less distortion. You can see this in the specs. A simple way any speaker manufacturer could make their product sound smoother and more detailed would simply be to make the speaker higher impedance. High end audio isn't about sound pressure so much as it is about nuance. Getting drums right is going to get other sounds right too- you get closer to the music.
