Magnus MA-300 vs. Innersound DPR-500

Hi,
Anybody has experience with these two amps ? How do they compare in driving low impedance load, musicality, transparency, sound stageimaging, etc ? DPR-500 retails for $14000 and MA-300 retails for $12000. Both have similar power output 300 W/ch (8 ohm) and 600 W/ch (4 ohm). On the paper the DPR-500 is stable upto 1 ohm load. The MA-300 does not specify anything below 4 ohm.

The question is which one is more organic, musical, transparent and can drive low impedence load and has high current capability ? I have not decided on the preamp yet. I will select a suitable tube preamp. My speaker has nominal impedence of 4 ohm but dips down to 2.8 ohm.
Your all input are most welcome.
Best regards,
topmostaudio

It would be helpful to know exactly what speakers you are driving. Also how big of a room they are in.

I own the DPR-500 but have not heard the Magnus. The DRP-500 should drive most speakers out there pretty well. The Magnus has less power on paper but weights 3 times as much. I'm guessing it's no slouch.

I like my amp allot and find it transparent. I do prefer to drive it with a tube pre in my system.

Innersound is out of business but the Sanders Sound Magtech amp is pretty much the same amp except the Magtech has a regulated power supply. It is also cheaper at only $5k new.

I am driving e-stat Innersound Kaya's with it. 500 wpc. See my system link below.

My previous SS amp was a Parasound Halo A21. Good for the money but could not drive my stats as well as the DRP-500. The A21 would clip on some sharp transients on the Kaya's. The DRP-500 is also much more revealing than the A21. I tried a couple of tube amps but neither had enough juice for my speakers and I did not want to deal with the heat of the bigger ones.

The regulated power supply in the Magtech is supposed to be better for magnetic drivers like in your speakers. I have not heard the Magtech yet. I think you can get a trial of the Magtech. If you call Sanders Sound you can chat with Roger Sanders about it and the differences between the Magtech and DPR-500. You could also call Magnus Audio and ask them if their amp can drive your speakers.

You have a nice sized room. I looked up your speakers and it looks like you just need to drive the midrange and tweeters with this amp. The bass drivers have their own amp. At 89 dbs sensitivity at 4 ohm I think your in the right power range for your room.

Just because someone else preferred the LSA does not mean you will. The only way your gonna know is if you try out a few amps and decide for yourself. In reality you could pick any high quality amp of the right power and get good sound as long as the other eq in your system matches up well together. It will take some time and effort to find components that give you the sound you want. There is no one right answer.
