I accidentally put TH900 on the maximum volume on DACmini can this damage them or I shouldn't worry that much ? (I simply love them)

Here's some good news looking at the specs of both the DACmini and TH-900s.
 
The MAX power the DACmin can output based on their website is 1.5W and the TH-900s can take 1.8W (according to the Fostex website). So you should be good with 300mW of buffer.

The HD800 are the faster headphones.  But the TH900 feel fast.  I think I've seen others mention this, but I attribute this perceived lack of speed with the diffuse nature of the soundstage the HD800 throws.  The TH900 are very fast for closed headphones though.

Agreed. Both are fantastic headphones, but technically speaking I give the slight edge to the HD800s. For a closed headphone, the TH-900s are the "quickest" most agile cans I've heard yet. (FWIW, this is with both driven by my GS-X w/ upgraded modules; the HD800s are run in balanced mode and the TH-900s are single-end).

Sweet !!! Thanks MacendonianHero , I was trying the difference between A1 and DACmini and I forgot DACmini volume to the maximum since I'm taking output from DACmini to A1.
As small review. I notice bass quantity Improvement In A1 but still It's not satisfying another amp on the way.

Balanced TH900, And .... ? Does this bring a real improvement on the sound or sound stage ? Isn't the advantage of going Balanced reduce With very efficient headphone like the TH900 ?

In other Words: I own à RedWine Audio amp With booth SE AND Balanced outputs. Should i rewire my TH900 Balanced ? Will i hear à différence ? :)

Thanks

Aside Question Magic Man: what câbling have you used ? Is Lawron's Queen cooper cabling Recommended With the TH900 ou do you recommand another câble ?


I'm using the cable it came with, just terminated for balanced operation (I'm keeping the OEM jack, in case I want to ever restore it to original). Also I have adapters for use with my SE amps.

The difference isn't large, but it doesn't take as much gain to reach an optimal listening level with my BA. They seem to be slightly more controlled, bass is more even and precise. I'm not sure if you'd think it's worth it to void your warranty, but it was for me.

Thanks. Do this mean that the câble has 4 wires all the Way ?

Have you noted the colors of each wire to use for each of the 4 pins ? Could you do a drawing/listing for me ?

Thanks in advance

Caution - at your own risk!!!

RED: Ring (Right signal line)
BLACK: Sleeve (Left and Right GND line connected in parallel internally)

I don't know the coloring, I had a guy do that for me (the arthritis in my hands keeps me from being able to solder).

Hubert appears to have it. :)

I just bought the Red Wine Audio Bellina HPA ( DAC/AMP with SE + Balanced output).  Will it be a good amp for the TH-900 ?  Has someone own or tested its predecessor, the Isabellina HPA DAC/AMP  ?

I think it'll be pretty excellent. I just got a TH900 delivered a couple hours ago and am running them off the ALO Amphora (same headphone amp as the older generation Isabellina - the one with no tube stage).
 
So far... sounds wonderful. giving the Stax 007 mk1 a run for the money.
 
(note: DAC is W4S DAC1 for both)
