Can I monoblock the ZOTL10 Mk II amplifier?


Yes. All our power amplifiers can be used as either stereo or monoblock amps. You can switch back and forth between the two modes via a switch on the back of the unit.

When used in mono mode, power output of the amp doubles. For example, the ZOTL10 Mk II amplifier outputs just over 20 watts per channel in mono mode.

What does the ZOTL10 Mk II amplifier sound like?

Here is how a selection of reviewers have described the ZOTL10 Mk II amp:

Part-Time Audiophile Review:

While it’s not exactly the “classic” sounding vacuum tube amplifier in many respects, it does seem to preserve those things that tubes do really well (think open, unfettered sound with highly natural harmonics) while minimizing their perceived shortcomings. This amplifier earns my accolades for its stunning sense of clarity, transparency, and precise spaciousness of sound.

Enjoy The Music Review:

I am smitten with the ZOTL10 MK II. Its brings out the best in any music you play through it. Rock, jazz, classical, pop – it doesn't matter. What made it so difficult to review this amp is the reviewer part of my brain would keep shutting off and I would just start listening to the music. I can't think of any better compliment than that.

The Audio Beatnik Review:

The ZOTL10 Mk.II also gave me a very realistic musical presentation… It plays music with wonderful harmonics and richness but with musically quick transience and very nice bass control. Mentioning the bass, it was able to carry the music with a really good rhythmic drive. The bass was also very well defined but not overly tight, and there wasn’t the least bit of “one-note bass.” There was also a very natural air around and within most bass instruments.

The top end was smooth and very extended. String and woodwind overtones were played beautifully. I was particularly impressed with the air around reed instruments and with the bite of horn instruments. Another important job of the top end of an amp is to have enough detail to help place the instruments and voices as they should be on the soundstage. In this area, I was very happy. The soundstage and imaging were very well portrayed by the Mk.II.

Do LTA amps have subwoofer outputs?

Most of our amps do not have dedicated preamp/subwoofer outputs. The good news is that you can still use the speaker outputs on any of our amps to connect to your subwoofer, and this is a common and recommended solution.

You will need a subwoofer with a "high-level" input, often called a "speaker-level" input, which again is pretty common. (If your amp doesn’t have this sort of input, the preamp outputs from the MZ2 and MZ3 will work for line-level subwoofer connections.)

This method of connecting a subwoofer is recommended over a dedicated subwoofer/preamp output because it ensures that your subwoofer and speakers are using the exact same signal.

Don’t take our word for it. REL, maker of some of the finest subwoofers in the world, recommends using this method for connecting their subwoofers to amps of all kinds:

Using the High Level input is always the best option. Using the High Level Input, instead of the Low Level Input, and connecting to the speaker output terminals of your amplifier is one of the unique secrets of REL’s success. When using the High Level input, your REL is fed the same signal that your main speakers are receiving. When connecting to the High Level input on the REL from the amplifier, you capture the sonic signature of your main system, including the tonal balance and timing cues of the entire electronics chain.
