![]() ![]() Upcoming Amarra 4 Release The excitement grows as we're on the verge of releasing Amarra 4! We appreciate the continued support of our loyal customers and want to inform you about the paths available to enjoy our new products.Īmarra Hifi UsersUpgrade to Amarra 4 for just $29.99 and take your musical enjoyment to the next level. This goes to show that even with one of the most accurate mics money can buy, you still need to use a good calibration file when doing these types of measurements.So the upgrade cost from 3.0 to 4.0 is $25, would someone from Amarra like to say how much the upgrade is from 3.0 to Luxe and for those who have already bought 4.0, the cost from 4.0 to Luxe I also tried it without the calibration file and didn't like the sound in the HF as much. Of course, I prefer the on axis filter over the 90 degree one used with the calibration file. My earthworks mic came with a fabulous calibration file which was only done on axis. I also created different filters for on axis and 90 degree measurements. I have four filters loaded into the DAP so I can easily switch between different filters. The image is slightly more refined and accurate. ![]() ![]() In my system, the 9 measurements in the cube formation in the seated position is best. I know some folks feel the sofa arrangement is better. I have also tried both the sofa and the seat 9 measurement configurations. But I think some folks have lower voltage DACs or preamps and need the extra gain. My DAC has plenty of headroom so it's no big deal in my case. With the new DSP gain function, you can also reduce the negative gain if the volume is too low. In my case, my amps are also Krell and my speakers can handle the extra work in the LF without bottoming out or any extra audible distortion. I think that's something to watch out for sure. I am showing the DSP gain function.Īmir brought up a good point about gain being reduced to allow for bigger positive corrections. I also posted some shots of the new version of DIRAC. I thought I would post some shots of my measurements. It looks like the 10dB boost is the limit, since it left that dip at 55Hz down about 5dB from the target curve. At any rate, the software has built-in boost limiting, to prevent overloading your amplifiers. It appears that ~ 55Hz has been boosted by 10dB, which lies in the subs' range. Note the dB scale on the left to see where the levels have been changed. I have heard them play much louder than I ever listen to them during their calibration and demo modes, so I think we're OK there, too. The biggest changes are in the response of my twin JL F113 subs, which each use 2500 watt amps. I did not see such crazy response using the app on my iPhone called Spectrum Analyzer, so a calibrated quality microphone is truly necessary to get this right. I thought it would be educational to show how bad a "good-sounding" system can measure, and what magnitude of improvement can be gained. The preamp volume control does not require much more gain to achieve listening levels, if any at all. My Krell EV403 doesn't work very hard to play very loud, so I don't think it's a problem. Special WBF thanks to dallasjustice, whose generous assistance got me through this without inducing a cerebral aneurysm. Fair enough, but I'd estimate the correction as being the equivalent of 10's of thousands of dollars in hardware upgrades. Many of you may say that your room/response is far better than that in the pictures. I didn't last long listening to things as they were for very long! You may switch the correction on and off instantaneously if you want to do comparisons. It didn't take long, though, to realize that something special was going on, and that many of the proverbial "veils" had been lifted. Period.Īctually, it was hard to listen to the system at first, since I had become so accustomed to "hearing through" the previous distortions that were present. ![]() This is another case of wanting to revisit your entire collection.ģ. It's almost eerie as you listen to recordings you thought you knew. The "see-through" clarity is a gargantuan step ahead. A voice sounds much clearer, and instruments remain the same size as they play up and down their respective registers.Ģ. Imaging is much tighter and more believable. While I know that my room is far from ideal, I've had many audiophile friends that thought things sounded very good (remember I was using some primitive EQ, so the shown graphs are not quite representative of the actual listening conditions).ġ. I cannot overemphasize what a tremendous difference this software makes to the listening experience. ![]()
