You may remember in August of last year, we published an article looking at three ‘entry level audiophile' headphones – all around the £150 mark. Well, today we are at the opposite end of the spectrum, as I have upgraded my audio setup with the Sennheiser HD 800 S headphone and the HDV 820 amplifier – a combination that will set you back just under £3500.

We first looked at the HD 800 S headphone in April 2016, when we published a full review of Sennheiser's flagship model. It is a beautifully crisp and clear headphone, with an incredible amount of detail to the treble that is still presented in a smooth, non-fatiguing manner. I even reckon it is great for gaming thanks to the immense soundstage which translates really well in PUBG, for instance.

You can buy it for £1399.99 directly from Sennheiser.

Pros

• Beautifully detailed treble that is not at all sharp or sibilant.
• Clear, transparent mid-range.
• Sub-bass extension is excellent.
• Huge soundstage.
• 4-pin XLR and 1/4in cables included.

Cons

• It is £1399.99.

• Dynamic range: > 115 dB @ 600 Ω load (A-weighted)

Sennheiser's top-end amplifier, the HDV 820 is nothing short of a beast. It is very well made thanks to its anodised aluminium panels, while it sports a total of four headphone outputs. There is also a huge range of input options, including USB, optical, coaxial, balanced XLR and RCA. With a very clean and refined sound, it makes for a fabulous partner to the HD 800 S as the headphone's natural detail is only enhanced by the HDV 820.

You can buy it for £2099.99 directly from Sennheiser.

Pros

• Clean, neutral sound presentation.
• Four headphone outputs.
• More inputs than you could possibly need.
• Very well built.
• Looks very sleek and minimalistic.

Cons

• It is £2099.99.

KitGuru says: It is not a cheap headphone/amp combo by any means – but the HD 800 S paired with the HDV 820 makes for an absolutely incredible sonic experience.
