teo audio,
I haven’t heard the affects of music described like that before but I liked it.
Well said!
Thank you,
Tim

Class D = Trash?
So, I'm on my second class D amp. The first one, a Teac AI-301DA which claimed to use an ICE module, was unlistenable trash. I burned it in for a few weeks, it just couldn't perform, so I sent it back. Following that, I tried the new Emotiva A-300 (class A/B). It was significantly better, but lacking in too many ways for my tastes. So I changed gears, got an 845 SET from China -- and it was an immediate and massive improvement.
So, before I went further down the SET road, I wanted to try a better class D product using a modern class D module. I settled on the D-Sonic M3-800S with the Pascal module and custom input stage. I read from reviews that these things like to have big cables, so I picked up an eBay 8 gauge power cable (Maze Audio, el-cheapo Oyaide copy plugs, braided 4-wire cable) to go along with it.
Mid-range GONE.
Soundstage depth CRUSHED.
Euphonics DISAPPEARED.
Yes, resolution went up. Driver control went up, allowing me to play compressed rock/pop and orchestra with the speakers being able to render it all. But enjoyment in the sound is basically gone. Using my best power cable (LessLoss Original) improved performance, but didn't fundamentally change the amp's nature. I ran back to my headphones (Focal Utopias) to detox my ear canals.
So, how long does a class D need to burn-in? I want to give it a fair shake before writing the technology off forever.

All, the aforementioned "red hering" suggestion that upwards of 1000 hours and sometimes more might be required to break in a class D amp, or for what it matters, a class A/B amp, SS or tubed linestage, or CDP comes from me. Over the years I have broken in a number of pieces. They all eventually stabilized with break-in times largely hovering around the 1K hours mark with some exceptions. Many of them created eventually thir own special kind of magic. Some did not at all, no matter my persistance. Shown below are only the ones which in time delivered real music: Aragon 4004 (A/B) approx 1K hours Rowland M312 (D) approx 1K hours Bel Canto REF1000 Mk.2 (D) Approx 1K hours Bel Canto REF500 (D) approx 1K hours Rowland M625 (A/B) approx 1K hours Rowland M725 (D) approx 1K hours Rowland M925 (D) More than 1500 hours Merrill Veritas (D) approx 1100 hours Merrill (Teranis (D) approx 600 hours ARC LS2B (linestage hybrid) approx 1K hours ARC REF3 (Linestage tube) approx 1K hours Rowland Capri (linestage SS) (approx 1100 hours Rowland Criterion (linestage SS) approx 1100 hours Rowland Power Storage Unit approx 200 hours Rowland Aeris DAC greater than 1500 hours Esoteric X-01 (CDp SS) approx 1K hours Esoteric K-01 (SS CDp) approx 1200 hours GamuT CD-3 (CDp) approx 800 hours As for warm up from power-on time for a well broken-in piece, I experienced it to vary from about one hour to about one day. I claim no particular scientific knowledge. I purely rely empirically on my own old ears, which I have used one way or another for listening, studying, and occasionally performing music for some 60 odd years. Doubtless, other equipment might behave differently. Besides, you might not experience the same long break-in curve as I did. If your quest for sonic nirvana is on a steeper curve, more power to you.... But if you find that after a couple hundred hours of installing a new piece nirvana has not yet reached you, you may want to wait a bit before succumbing once again to Upgraditis Furiosa.... Patience can be Golden! G.

@guidocorona Great post, thank you. I completely agree with your observations. I have yet to purchase a piece of gear, be it cables, DACs, amps or speakers that didn't take 500-1000 hrs to break-in completely. Moving anything in my system also guarantees another three to seven days of settling-in. In light of that my gear tends to have more dust underneath it than most.:-) Cheers, Scott |
I kind of doubt anyone can actually track the sound of something breaking in, even though break in is probably real, since there are too many variables, e.g., weather, time of day, day of week, many others. In addition, any audiophile who’s going to keep track of the sound and determine when exactly a given component or cable or speaker has completely broken in will most likely be breaking in more than one thing at a time and will be adding tweaks all the while. In addition, if I can be so bold, unless a purpose built break-in device is employed the chances are slim to zero that the component is question EVER breaks in completely. The music signal doesn’t cut it. There’s just not enough time to do everything that should be done without being slowed down to a snail’s pace by having to sit on one’s thumbs for 200 hours or 600 hours or whatever while something breaks in. Give me a break! |
guidocorona So you are saying you have spent over 19,000 hours burning in and doing interval listening to all the above amps while discerning audible changes at regular intervals? LOL...I don't believe everything I hear, and especially everything that is posted on audiophile forums by self-professed golden ear types. |
