Best LD amp for B&O Play H6 2nd gen headphones? I+ vs. MKII

[erlebach]

Hi,
I own the Bang & Olufsen (B&O) Play H6 2nd generation headphones. I can't find any official specs regarding impedance or sensitivity. Some web site declare 30 ohms impedance and 97 dB sensitivity. Measurements at Innerfidelity show the following results:

Impedance: 38 ohms (min: 35 ohms)
Volts RMS required to reach 90dB SPL: 0.045 Vrms
Power Needed for 90d BSPL: 0.05 mW

I use a MacBook Pro as source and I seldom go beyond 50% volume. Usually I listen at 30% volume which is loud enough for me with these headphones.
What's the best LD amp match for these headphones, I+ or MKII ?
Thanks in advance!

The Little Dot I+ would be a great pairing here. You'll have plenty of current for full dynamic range and there's really no reason to spend more.
