Why tube amps are rated so low, still don't get it


Hi Guys,

I am still very confused as to howcome tube amps are rated so low, and how to tell whether the amp will be able to power your speakers properly. In particular I am interested in the Shanling SP-80 tube amplifiers for my system. This is since I have the CD-T100 and I want to partner it up with the amp for the synergy. The amps are rated at 50W each (monoblocks). Is that enough? How do I compare it to a SS amp? I tell someone 50W SS and they laugh, but I say 50W tube and they call it a monster! I am still very confused!

Thanks for any help/explanation,
X

Hi There,

Thanks for the info! Is there any way in being able to estimate if the amps (Shanling SP-80) will be able to drive the speakers? What factors must I look at besides the speaker power handling and sensitivity rating?

Thanks,

Hi There,

The speakers are not 100% certain yet. I am busy deciding (will decide this week) which ones I will go for exactly, but the top two candidates and their specs are as follows:

Monitor Audio GR-60
Frequency Response +/- 3dB 28Hz-30KHZ
Sensitivity (1W@1M) 90dB
Nominal Impedance (Ohms) 6
Power Handling RMS (W) 200
Drive Unit Complement 2 x 6.5" RST® bass, 1 x 6.5" RST mid,
1 x 25mm Gold Dome C-CAM tweeter
Bass Alignment Triple chamber differentially tuned sealed mid-section reflex bass sections
External Dimensions cm approx. 106Hx20Wx33D

Elac 209 Jet
Dimensions H × W × D 1030 × 200 × 285 mm
Gross Volume 58l
Weight 19 kg
Principle 2½-ways, bass reflex
Woofer 2 × 180 mm AS cone
Tweeter 1 × JET
Recom. Amplifier Power
at Nominal Impedance 30-300 W / channel
Crossover Frequencies 2,500 / 2,700 Hz
Sensitivity 90 dB / 2.83 V / 1 m
Nominal Impedance
suitable for amplifiers (from ... to) 4 Ohm
4 ... 8 Ohm
Minimum Impedance 3.5 Ohm at 190 Hz
Frequency Range 32 ··· 35,000 Hz
Nominal / Peak Power Handling 160 / 200 W

Any suggestions? (on both the speaker choice and whether the tube amp will work well with the)

Cheers,

Hi There,

I'l be honest with you - Shanling is not available here. I tested out the CD Player when I was overseas and fell in love with it, so I imported it specially. The tube amps I will thus not be able to test.
