    I've decided to try out the bi-amp facility of the Yamaha RX-V0267. I have a 5.1 setup and I also have front presence speakers. I would like to keep the front presence speakers in use, but the only way to do this whilst also bi-amping the two main front speakers is to use an external amp in conjunction with the Yamaha's pre-outs.

    So, as getting equipped with 4 channels' worth of power amp kit for bi-amping the two front is pretty pricey (the fronts are Quad 21ls), I'm wondering about using a small external amp for just the two front presence speakers (which is doable according to the manual).

    My question is, what would be a suitable external amp to power two Quad l-ites (100w rms, 6 ohms)? Quad recommend amp power of between 30w - 120w for these speakers, but as they're only used for front presence effects, what could I get away with? A remote on/off function that works with the Yamaha's trigger function would be handy, but not essential as I understand external modules can be used for this.

    Has anyone tried this?

    They'd not be suitable for powering the main fronts due to their lack of power. You need something that at least approximates the power output of your amp's own internal amplifiers. I'd also question the quality of these amps given their price. You basically pay for what you get with power amps. You may get away with using one to power front presence speakers though, seeing as these don't need as much oomph to them as you main speakers and fidelity isn't of upmost importance.

    Maybe look at secondhand power amps?

    I've got Quad 11L2s as my front speakers, and I'm driving them, bi-amped, from a Linn Majik/LK100 combo via the pre-outs on my Denon 3312. Up until a few weeks ago, I was using a pair of L-ites on my iMac, driven by the Majik.

    These Linn amps are pretty low-powered - 33 watts for the Majik, 50 watts for the LK100 - but they are more than a match for the Quads. LK100 power amps go for around £150-£200 on eBay I think. I guess people avoid them because they appear to be too low-powered.

    That's useful to know - thanks. I've found a few Linn LKs on ebay so might try my luck...

    As an alternative, which would sound better, do you think: the Yamaha 2067 bi-amping the front speakers, or using a Rotel 976 Mk ii 6-channel power amp to bi-amp the fronts, using the 2067 pre-outs?
