I used the Auxiliary and Bluetooth inputs and then loaned the MP to an audio amigo, Mr. Phono (typically used with raw moving-magnet phono cartridges – no upstream RIAA equalization or line-level converters, please).Auxiliary (typically used with CD players, streamers, tuners or other line-level analog sources).When speakers are reconnected to the MP, remove the dummy resistors. A single 10-ohm, 10 Watt resistor (available via Amazon – you’ll need two – one for each channel) should be connected across each pair of speaker terminals (red to black for each channel) to avoid damage to the EL-84 output tubes. If the owner wishes to use the MP as a preamp only (and without attached speakers), then a dummy load must be connected to each pair of speaker terminals. This is a problem and could conceivably lead to damage of the MP. If the pre-out jacks are being used to drive an external power amplifier, there may not be any speakers connected to the MP’s terminals. This is true insofar as it goes, but fails to address the situation where an owner wants to use the MP as a tubed preamplifier only. “Do not turn on the amplifier without first connecting a pair of 4-8-ohm speakers.” This means that there will be no way to eliminate bass frequencies from the satellite speakers (or the amplifier’s output tubes) despite having subwoofer(s) on the pre-out jacks.

This should not impede the average user, but a potential purchaser should be aware of it.Īnother important factoid not mentioned in the owners’ manual is that those pre-out jacks are full-range and that the speaker outputs are also full-range, regardless of whether subwoofer(s) are used with the main speakers.

However, the volume available on the pre-out jacks may be insufficient to drive some amplifiers (mostly pro amps that need more input voltage) to full volumes. This allows the use of the MP as a standalone tube preamplifier or allows the user to drive one or more subwoofers from the pre-out jacks. On both my review sample and at least one other unit owned by an online amigo, the pre-out jacks are volume controlled. “The output level of the PRE-OUT jacks is unaffected by the volume knob.” The setup of the MP is easy, but the owners’ manual contains at least one error and omits at least one important caution. It seems of sturdy construction for the most part, and mine was easy to use. The Monoprice Pure Tube Stereo Amplifier is built in China and sold by the ubiquitous here in the USA. So, explain to me again why you need that gazillion-watt AVR that sounds like badly wounded cats fighting? The occasional raucous holiday party excepted 10 watts will get you where you need to be. The MP will play loud enough for your home just fine. But if you’re listening at those levels, sound quality is academic anyway because you’ll soon be deaf. The MP will, admittedly, not play at stadium levels.

More loudness increases the wattage demands very quickly, but for most listeners, the first watt alone will suffice, and the remaining nine will easily handle any unexpected crescendos. Beginning to get uncomfortably loud, yes? Now you’re approaching 90-ish decibels.

Now get out your cell phone, download a free sound pressure level app, sit in your listening chair, and start cranking up the music. And even that is measured only at 1KHz, not 20-20kHz.īut do you REALLY need more? The average loudspeaker sold in 2020 is highly sensitive (normally from 90 to 94dB / 1W/1m). As to the Monoprice Pure Tube Stereo Amplifier (henceforth the “MP”), let’s dispel the biggest misconception first: I can just hear the voices of the unwashed mob screaming “ONLY 10 WATTS?!?” Yes, it truly has only 10 watts-per-channel output.
