Hello, audiofolk. Fisrt time posting here, and I have a doozy for you all.
My interface is a TASCAM UH-7000 and My Headphones are Sennheiser HD600. The Tascam has no problem driving the HD600's, and by that I mean that I rarely have to turn the volume knob past 12 o' clock. But I never verified whether the Tascam was a good fit for the Senn's before buying. So a few days ago I got curious and read the Tascam manual and found that the only information regarding the headphone amp is this tiny and confusing (for me) sentence:
Maximum output: 45mW + 45mW or higher (THD+N 1% or less, into 32 ohm load)
Now, I know that this isn't a dedicated headphone amp but I was still surprised that that is the only information provided on the manual.
So my main question is: Are those specs good for the HD600 or do I benefit from a Schitt amp or something similar to get the most of my HD 600?
But beyond that, What does "45mW + 45mW or higher" mean?
I used a Headphone Power Calculator (https://www.headphonesty.com/headpho...er-calculator/) to better understand de HD600 power needs. It states that the SENNs, with
a sensitivity of 105 DB(1VRMS) and 322 OHMS impedance, require 10 mW or 1.82 volts RMS to achieve 110 DBSPL of loudness or 34mW (3.19 volts RMS) for 115 DBSPL.
Somewhere I read that 115db of loudness is ideal for soft/old music (and I do listen to a a lot of old jazz, samba, tango)
Are the stated 45mW in the Tascam per channel (45mW left and 45mW right)? Is it 45mW divided by two?
The Magni 3 specs in contrast: Maximum Power, 300 ohms: 410mW RMS per channel. Thats less than 1/2 a watt per channel.
How many wats per channel are ideal for the HD600 and can we know how many wats per channel the Tascam has based on: 45mW + 45mW or higher (THD+N 1% or less, into 32 ohm load?
Woe is me.
I know thats more than one question and a bit all over the place, but I hope its fun enough for those of you with a good understanding of these technical concepts to help out a newbie.
