How do I use an SPL meter to measure the volume of an amp? The ones I have found only seem to measure via the microphone.

That is about it, play a test tone with a headphone connected to the amp. Just run the SPL meter app on your iphone and put your headphone as close to the mic as possible. Adjust the volume on each amp you are comparing until both reach a level you are comfortable with. I set the volume at 80 -85 dB when I compare amps.

Thanks Headwhacker. I'll try it.

Ok. Finally got around to checking this out. To do a really accurate test I need a friend to switch between amps.
This is what I think is going on.
I reckon that there is a hardness to the top end of the Arrow which is not there in the O2.
Switching between the two sources with levels matched as accurately as I can.
I was fully prepared to be wrong about the Arrow but maybe expectation bias is responsible. The difference is very small but I know which amp I would rather use for the 600's.
I will try and enlist a helper to do a blind test.

A very good idea.

 

Can't comment on the O2 as I've never heard it but I've used different gen Arrows and have never found it to be harsh or even bright when compared to other amps. In fact I was happy with the addition of the treble switch.

 

I owned the HD600s and the HD650s at the same time for awhile. I sometimes found the treble to be too much and the bass/fullness too little with the 600s regardless of the amp I used. It isn't that I would never use the 600s as there is some music that sounded better with them. I just find the 650s never give me the brightness fatigue I sometimes experienced with the 600s during extended or high volume listening.

 

 

 

Different strokes....

I don't post very much but I just wanted to say that I have greatly appreciated your comments over the last four years or so, particularly regarding the Arrow amps.  I have a 2G and a 4G.  I like the darker 2G with my Jays V-Jays (24ohm) portable on the ear phones.  The 4G is a really nice amp also but it is a bit intense in the upper midrange and treble with my Jays V-Jays (even with the treble off at 0.) On the other hand, the 4G does sound great with full size cans, like my HiFiman HE-300's - played through a Music Fidelity V-DAC.  I would probably be better off with the 4N because it has the same opamp AD8397 as the 2G.  I like the HD650's and so I was interested in your comment relative to the HD600's.  I was thinking of buying some HD600's but may research further because I am sensitive to piercing upper mid's .   The 650's are great!

Thanks for the comment. I don't think I'd call the 600 piercing by any stretch, especially compared to Grados or cans like the DT880s.  I just prefer the 650s with most music as I find they have a more muscular sound (for lack of a better word). Any music without much bass such as baroque classical can sound as good or better on the 600s.

 

For a desktop I use a balanced set-up and a silver cable with the 650s. To my ears I've taken care of any lack of detail or high-end extension I might have been missing with the stock cable or even a good aftermarket copper one. Having said that, I sometimes wish I still had the 600s to use with the single ended Cardas cable I own. Maybe if/when I find a good deal on a pair ;)

 

Thanks again for your friendly reply.  I'm happy if I offered help of any sort.
