What else to know about the Krell Vanguard Integrated?Krell have been very generous with the feature listing on this Integrated version and as usual the build quality is exceptional for a product of this type and from a manufacturer who has a long history for building high quality products. The Vanguard has a massive 750VA toroidal transformer and 80,000 microfarads of storage capacitance, this gives the amp an enormous amount of power on tap and it kicks out 200 watts into 8ohms and doubles to 400 watts into 4ohms. This is the same as it was on KAV-400Xi but with the Vanguard it has more capacitance as the older Krell only had 55,000 microfarads of storage, this therefore gives the Vanguard more current storage available and more current when needed. With the digital board fitted it really does up the spec and makes the standard analogue version into a real powerhouse as it can become your center hub for all of your music and digital needs. It has an ethernet connection at the back of the unit and also excepts Bluetooth which works exceptionally well, but more on that later. It also features two HDMI sockets IN and an HDMI OUT so you can use it with a 4K screen as it will allow 4K to bypass through the amp such is the wide bandwidth of its video circuitry. This is great if you want to play PCM music from your Blu-ray discs in 2 channel format and watch it on your 4K Ultra HD TV. It is also features SDPIF connections, one optical and one coaxial, and then with a USB on the front of the unit if you wanted to connect a USB stick with music on, which it will also play. The Krell guide suggests to download the App mConnect which is a free software to use on your iPhone or iPad which can then set you up to use the Vanguard to stream all your digital music which you may keep on HDD. I have a lot of my music on HDD and hooked the Ethernet port up and connected straight away and downloaded the App. It could not of been simpler, and then looked for my NAS drive and all my music, you can then play all your music through the Vanguard Amplifier. This time round Krell have thought about the heat dissipation that really made the older KAV-400Xi like a radiator and put in two small fans at the rear of the unit to suck out the heat. They are very quiet when in operation and you cannot hear them when on, and it keeps the amp a lot cooler than the older 400Xi, which is a good thing. The preamplifier section of the Krell is a fully discrete Class A which is taken from Krell's top of the line Illusion preamplifiers. Krell's Current mode technology is also used to assure unequaled signal bandwidth.
