Review: I’ve had the X7 for over a month now, and it has been an extremely enjoyable purchase. I’ve had tube components before, but never an integrated tube amp or tube amplifier. But I’ve very much enjoyed the tube preamps I’ve tried and the tube phono preamps that have been in my system. Buying the X7 was a leap of faith on my part. I’ve always wanted a McIntosh tube integrated, or maybe a Rogue Audio tube integrated, but the high costs of either have always held me up. In addition, I was concerned about the drop in power ratings when moving to a tube amp. I have a pair of MartinLogan Motion XT 100 towers that like a little power to sound their best, and have been using a 150 watt per channel Rotel integrated to push them. But I haven’t been pleased with the sound quality I’m getting through the Rotel so wanted to make a change. Enter the X7. Four KT88 tubes = 25 watts per channel in triode mode and 45 watts per channel in ultra linear mode. Point to point wiring inside the case. Two 12au7 tubes and one 12ax7 tube, and the X7 uses a rectifier tube, which not all tube amps have. I ran the X7 with the included Muzishare tubes for a couple of weeks, and then started rolling tubes. I purchased a Mullard rectifier tube, a Gold Lion gold pin 12ax7, and then tried a series of 12au7 tubes before ending up with a couple of new release mullards. I swapped out the KT88s with PS Vane Horizon series tubes, but didn’t like them. I bit the bullet and bought a set of Gold Lion KT88s and that is where I stopped. I couldn’t imagine the X7 sounding much better than it does now. Much better than the solid state electronics that were running the MartinLogans prior. I use the 4 ohm taps for the MartinLogans and run it in triode mode the majority of the time. This gives a smooth, slightly rolled off treble and plenty of low bass definition. When I really want to turn the volume up, I switch the X7 to ultralinear mode and enjoy a sparkling treble and increased volume. With the right set of tubes, the X7 performs amazingly. The stock tubes were good, but the combination of Mullards and Gold Lions is a revelation. The KT88 upgrades were 300 dollars. The Mullard rectifier tube was 60 bucks. The Gold Lion 12ax7 was 55 dollars, and the pair of Mullard 12au7s was 55 dollars. Adding all that up, from X7 to upgrade end game cost me less than 2000 dollars. Less than 2000, and it sounds better than the 3500 dollar solid state integrated it replaced. 2,000 dollars is a lot less than the cost of a nice Rogue Audio, Luxman, or McIntosh tube integrated. One heck of a value here! Couple additional items. The X7 has a balanced input. That’s what I run my Cyrus Signature phono amp into. The built in phono pre of the X7 is pretty average to be honest. I wouldn’t plan on using it for critical listening. The VU meters look amazing. It is beautifully built. Sounds great.
Review: My first experience with a tube amp other than small headphone amps. My main system uses a Bryson 4bsst amp pushing large Mirage OM5 speakers with active bass drivers, and also a Paradigm sub, so quite a change, but this will be a secondary system for me. The Muzishare would be challenged driving the OM5s, so I purchased both a set of Klipsch rp 600m’s and also Triangle Borea br03’s to pair with the X7.... both highly sensitive and with their own sonic signature, and both emphasized top end, especially the Klipsch, so great match for tubes. I swap in and out depending on my musical flavour of the day. Both speakers hooked up wonderfully with the X7 and serving as great introduction to tubes other than headphones. The X7 sounded great out of the box and after a week of heavy listening has truly come into its own. This amp drives both the smaller sensitive speakers to more than enough sound pressure levels without running out of breath...lots of headroom, and demonstrates sweet treble and mids with lots of bass power that is quite defined when in ultra linear mode. Imaging is very good as is the soundstage, which was extra wide in triode mode that I use late evenings and provides more of a tube sweetness and warmth that is evident with piano and string instruments, and vocals. The amp is very heavy (almost as much as my large Bryson) and quality construction with a solid feel to the volume and selector knobs and also toggle switches....very good quality binding posts. A really attractive piece of gear as well and has to be seen in person to fully appreciate. I enjoy the glow of the tubes and VU meters in a dark room. I am using vinyl, CD, reel to reel tape and streaming for sources and sounds great with all. The phono stage is very good as well, and also with drives my most demanding headphones with ease. I am very pleased with this amp and considering this my introduction to tubes, a very good value....truly great value for the performance and build quality. I recommend.

Excellent. Well packaged and arrived in pristine condition. Currently around 8hrs on unit. Was a bit dull and scratchy at first, but after a couple hours of run time it improved greatly and bass slowly picking up, but sound output is quite neutral overall which I like. Only thing I noticed was the v1 output while checking the bias seems to wander a bit, although getting more stable with run time. I thought the power tubes might be mismatched by looking at the clock position of the bias pots. However, after swapping the power tubes around for a possible better match for each channel the clock position was the same as original after readjustingthe bias. So I believe they were well matched as the unit came. Very nice amplifier and would recommend to anyone.
