Terminology in the world of hi-fi can sometimes be a funny business. Some names and descriptions have been in use for decades. The ongoing change in how we listen to music means some of them have joined together in new ways which is why some network players including our CXN and 851N are sometimes described as 'streaming/DAC Preamps' combining the functions of a number of different units.
One term that does seem to be used less and less is 'stack system.' It referenced the ability of separate electronics to be placed on top of one another to save space and give you a mighty “tower of power” formed by your equipment. The term might have fallen slightly out of popularity with the public but it hasn't affected the ability of equipment to stack on top of each other. A worthwhile question however is should you do it? And what do you need to look out for if you do?
In our case, we design all of our separate units to support more weight than its own. As our units tend to be reasonably large, placing each of them on its own surface isn’t always going to be an option. We always ensure our equipment, where possible distributes its weight evenly so that if it’s stacked, it doesn't place an uneven load on the surface it’s on. We also make sure the base of the feet on our products are soft so they don't mark the surface they’re placed on. They're extremely grippy too so equipment shouldn't move around too easily.
So within reason (we'll get to this a bit later…) you can safely stack your equipment on top of one another. There are some other things you need to know though. The first is your amplifier, or if you’re using a separate pre and power amplifier the power amp section. The amplifier needs to be able to radiate any heat it generates whilst it’s in use so placing devices on top of isn’t something we’d encourage. Whether you’re using our equipment in your stack or units from another brand, we recommend that the amplifier/power amplifier is placed on the top of any stack of electronics.
