105 SILVA vs POET: which needs more amplifier?

The Meze 105 SILVA is 42Ω at 112.0 dB/mW; the Meze POET is 55Ω at 101.0 dB/mW. This page covers what they ask of an amplifier, not how they sound.

The POET needs 11.0 dB more than the 105 SILVA to reach the same loudness — 0.79 mW against 0.06 mW.

What separates them

Where the two part company

Every source in the database that drives one of them drives the other. On power, the choice between these two changes nothing about what amplifier you need.

14 sources stay below the audible-hiss threshold with the POET but cross it with the 105 SILVA (FiiO BTR11, FiiO K11 R2R, Lake People G103-S Mk II, 11 more).

280 of the 280 sources here reach 100 dB on both.

At the level you actually listen at

What each one needs from 80 to 105 dB

The POET is more demanding than 60% of the 567 non-electrostatic models in this database; the 105 SILVA than 12%.

dB SPL	105 SILVA power	105 SILVA voltage	POET power	POET voltage
80	0.6 µW	5 mV	7.9 µW	21 mV
85	2.0 µW	9 mV	0.03 mW	37 mV
90	6.3 µW	16 mV	0.08 mW	66 mV
95	0.02 mW	29 mV	0.25 mW	0.12 V
100	0.06 mW	51 mV	0.79 mW	0.21 V
105	0.20 mW	92 mV	2.5 mW	0.37 V

What drives both

The cheapest source that satisfies both

Source	Price	Headroom, 105 SILVA	Headroom, POET	Output impedance	Noise
JadeAudio JA11	$20	25.6 dB	13.4 dB	0.5 Ω	1.7 µV
FiiO KA11	$29	33.8 dB	21.7 dB	0.7 Ω	1.7 µV
FiiO BTR13	$59	30.8 dB	18.6 dB	0.6 Ω	1.0 µV

Of the 280 sources here, 280 reach 100 dB on both. 57 of them also publish an output impedance low enough for both under the one-eighth rule and a noise figure that stays below the audible-hiss threshold with both.

The cheapest of the 57 is the JadeAudio JA11, at $20. It leaves 25.6 dB of headroom on the 105 SILVA and 13.4 dB on the POET, its output impedance is 0.5 Ω against a one-eighth limit of 5.25 Ω and 6.88 Ω, and its noise figure puts the hiss floor 10 dB and 22 dB below the 20 dB SPL this site treats as the point where a quiet room stops hiding it.

Frequency response

What each sheet prints, and what it is worth

Model	As printed	Tolerance	Standard
105 SILVA	5 Hz - 30 kHz	not printed	not printed
POET	4 Hz – 96 kHz	not printed	not printed

Meze prints 5 Hz - 30 kHz for the 105 SILVA and 4 Hz – 96 kHz for the POET.

Neither range has a tolerance printed beside it, so a wider range on one sheet is not deeper bass or more treble.

Not a measurement; maker by maker.
