Yes, that was my point. The fact that most people's ears are sensitive to that audio frequency region shouldn't cause the dip to be noticeable while listening to most music. It may even be an advantage because it's compensating for the ear's high sensitivity to those frequencies.These are very good cans.
The human ear is quite sensitive to that region. I would not expect the average person to detect that alleged 6kHz dip. These cans are excellent! Only the self professed "Golden Ears" have said otherwise Or perhaps have narrower than average auditory canals which would raise their canals' resonance, thus sensitivity, higher in frequency.
Here is a very nice 50VA 15V toroidal transformer available for the LC:
You don't need accuracy to "match" transisters. "The 4 output transistors (BD139/140) have BEST performance at about temp 70°C" "The 4 Capacitors (470uF) have BEST performance at about 50°C"
I have always wondered about the LC temperature argument. You can use the argument that the transistors performance is optimized at a high temperature. But, at what cost to other components, especially capacitors? You will notice the latest version of the Matrix M-Stage (another Lehmann clone) has vents for cooling:
...posting a "graph" without a vetted source - brilliant!
[...] "Given the measurements I'm seeing, the iPhone's DAC is excellent and can produce very accurate output. [...] For sonic quality, therefore, the most important factor would be how well the headphone matches the amplifier. Assuming the iPhone 6 has an output impedance similar to the iPhone 5 around 5 ohms, a good ~40+ ohm set of high quality, high sensitivity headphones should provide excellent neutral sound. Not that lower impedance headphones would sound bad of...
They like the Grado's with "metal" because their THD levels are sky high. Plug that into their tube amp distortion and they have an eargasm - lol.Just my subjective opinion of course
Very strange!
