Stereo versus AVR - getting the best out of Kef XQ40s

Hi (first post!) I have an Arcam Alpha 8 CD feeding a Pioneer SL-CX85 AVR into Kef XQ40s via QED Revelation (bi-amped), integrated with a full AV system. For stereo it beats my other room stereo only systems hands down, and have experimented with using the CD DAC and the AVR DAC. However, I wonder if I am getting the best out of the XQ40s. Surprisingly, they do not suffer from over brightness, though I could imagine some improved clarity at higher volumes with complex rock tracks. I understand that I can integrate a stereo amp into the AVR system so the CD feeds straight into a stereo amp and drives the KEFs in stereo or AV mode. I wonder if I would I benefit significantly from an upgrade to the amp, or CD player, or by adding a DAC, and if so what would should I consider and how could I expect to benefit? I am loathed to spend a few £K on amplifier/CD/DAC just for a marginal improvement but if it would blow me away, I may start saving or looking around for used kit. I have very broad music tastes, mainly modern.

Hi Paul, and welcome to the forum.

As in all things hifi, you will often get diametrically opposite views; so it should be your own ears that are the final arbiter.

IMO. A stereo amp is well worth pursuing, and preferably one with HT by-pass (though it's not essential).

For my taste, the XQ range from Kef work better if the amp has a touch of warmth......so I would be looking in the direction of Arcam, Musical Fidelity, Audio Analogue, Unison Research, Sugden, Creek, Pathos and Electrocompaniet.

A good dealer should let you home dem (with a deposit).

Hi, I guess it depends on your budget - certainly every improvement in the source/chain that i've added has helped my XQ40's. I currently have a NAD M51 DAC which gets fed the CD/PC source. It's a digital preamp so could hypothetically be used with your power amp.

Borrowing a good DAC would help, the Kefs are very capable speakers and I'm not familiar with the Pioneer AVR but found moving up from a mid range Integra/Onkyo receiver yielded results too. Good luck

Currently using (Oppo BDP83/NAD M51/Arcam AVR600-direct mode/KEF XQ40's and REL subs x2/Kef IQ70's rear)

You're only surprised they don't suffer from brightness because others tell you that they are bright :)As an ex-user of an SCLX82, SCLX83, SCLX85, and SCLX86, I never once found any of them bright. If I hadn't moved on to AV pre-powers, I'd still be using the SCLX86.
