One of my objectives in my 43things list is to revitalise my hi-fi. Earlier this week I ordered a Mac mini which will replace my Slimp3 device and consign my Sonos dreams to the wastebasket. With the expected announcement of a Firewire-based audio device from Apple together with Firewave – Griffin’s new Firewire-based 5.1 system it looks like a good decision.

After the source components, the amplifier is the next most important piece of any hi-fi setup. My Arcam Delta 90 has served me well, but it lacks the inputs for future growth and knows nothing about digital input or home cinema. Fortunately, Arcam’s AV range has matured over the past two years to make me consider them having previously favoured Sony.

I’m not going anywhere near their FMJ range (made in Cambridge), but their Asian-made Diva range suits my list of requirements and budget.

First up is the A90 amplifier. This is a basic amplifier, with more inputs than my Delta and with optional Phono input and 5.1 outputs. The big problem is that it retails at £850 without these options.

The alternative is the AVR250 (product info | PDF review). This is a cut down version of the AVR300. The big problem with home cinema amplifiers is that they are not great at music, however the AVR250 is, and both have the capability of operating in stereo only and switching off all digital processing.

There are other big pluses:

• Numerous digital inputs – so I can attach both my DVD player and Sky+ box
• Support for external decoders
• Support for 7.1 input and output
• I have a fireplace in my lounge. This prevents me from placing speakers in an optimum position. Fortunately the AVR250 allows configuration of both output volume per speaker – which one would usually set using a sound pressure meter – and output delay (or distance)

The AVR250 retails for £1000, which makes it a more compelling choice than the A90 both in capability and longevity. Like the majority of amplifiers, there’s no Phono input, but these can be purchased from around £50. The NAD PP-2 Phono Pre-amp is my current frontrunner.
