great entry level amp

Reviewed Jun 25th, 2014 by Seeburger V200

This is a decent 'entry level' amplifier, and is quite capable, it does 'boast' the much hyped Technics new class AA output stage, but in reality i'd assume it to be a class 'B' amp (most certainly not a pure class A design) That said, it does 'sound' quite pleasing, and, of course your choice of speaker will influence reproduction greatly! Having listened to this amp driving a pair of Linn Index spkrs, i have to say it was impressive for a 'budget' amplifier, and in all honesty i couldn't distinguish this amp from the higher spec SU-X950 from Technics! On 'paper' the 301 has a claimed 50 watt channel output power, as opposed to the 950's claimed 60 watts, both have very similar specs in all other aspects, although, curiously the 'lesser' 301 has a 'claimed' S/N ratio slightly better than the 950!! 84db & 82db respectively. I would question the stated output power, but do 'they' mean 50 watts in music, RMS, peak(s) continuous, both channels driven e.t.c, e.t.c? For what it's worth, my guesstimate would be around 20-25 watts continuous RMS both channels driven. Maybe one day i'll actually measure it with 4, 8 and 16 ohm loads! Anyway, to sum it up, these amps can still be bought for small money, and (i think) represent very good value for money, there are far worse amps out there! The Technics SU-X301 won't power a discotheque, but for home HiFi it's a very good little amplifier that shouldn't cause you either headache or ear-fatigue........unless you WANT it to! Assuming you don't pay an inflated price for one, it should satisfy most folk. Although i currently 'use' a TEAC, i could and have lived quite happily with the Technics 301!
Thanks for reading, happy listening,

re: SU-X301

Sounds very nice..! looks great in the full component set stacked together and low foot print...!
The 50 watt per channel power rating is at Din measured at 1 Khz and also at a high distortion rating meaning its probably no more than a 35 watt per channel into 8 ohms with respect to a lower T.H.D distortion rating and also across the whole Band.
I think it very collectible with the tuner, equalizer, tape deck and Cd player

re: SU-X301

Collectible I don't know, but the x301 is nice sounding amp. I have this since 1991 with the tuner, tape deck and Cd player and speakers. The amp always worked fine, never given in repair! I have changed a few years ago only the Cd player after so many years he have stopped working... he is retired
