Dynamic headphones are far more different than most people realize. For the same sound pressure level the power needed with different headphone models can vary up to a factor of about 500! Impedances can be different to a factor of more than 20!\u003c\/p\u003e\n\u003cp\u003eThis is the reason why different headphone models have very individual requirements to the headphone amplifier driving them in terms of voltage and current. Everybody who once has connected a high quality headphone to any given standard headphone output knows about this problem.\u003c\/p\u003e\n\u003cp\u003eWith the launch of the Linear there is now a high end headphone amplifier to realize even the highest demands to reference quality headphone music reproduction.\u003c\/p\u003e\n\u003cp\u003eThe selectable gain (0dB, 10dB, 20dB) of the Linear effectively optimizes the output level of the zero global feedback Class A output stage. Practically all high quality dynamic headphones available will show their best possible performance, no matter if you have an easy to drive low impedance pair of headphones or an ineffective pair of 600 Ohms studio cans.\u003c\/p\u003e\n\u003cp\u003eCarefully selected top notch components and a highly sophisticated circuit design guarantee top notch listening pleasure. Now you can hear that ultra transparent sound and the explosive dynamics formerly known only from electrostatic headphones. An over dimensioned power supply with a huge magnetically and statically shielded toroidal transformer is included internally allowing a power cable of your choice to be directly connected to the unit.\u003c\/p\u003e\n\u003cp\u003eFor stereo setups with just one source like a CD player or a turntable with a phono stage the Linear is the simplest and most effective active preamp one can think of. All audio connectors including the two Neutrik phone jacks come with gold plated contacts. No external Y-adapter is needed!\u003c\/p\u003e\n\u003cp\u003eThe faceplate and the massive milled aluminium knob for the smooth running 27 mm ALPS high grade volume control are available in anodized black or silver.\u003c\/p\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDiscrete Zero Global Feedback output stage with high quiescent current ready to drive most headphones or long cable runs \u003c\/li\u003e\n\u003cli\u003eAudiophile voltage amplifier stage \u003c\/li\u003e\n\u003cli\u003eOnly MKP caps in the signal path for perfect transient response and ambience reproduction\u003c\/li\u003e\n\u003cli\u003eGain jumper selectable 6dB\/20dB\u003c\/li\u003e\n\u003cli\u003eHand selected potentiometer with very good channel tracking\u003c\/li\u003e\n\u003cli\u003eDouble sided audio board\u003c\/li\u003e\n\u003cli\u003eExternal AC power supply\u003c\/li\u003e\n\u003cli\u003eUltra fast rectifying diodes \u003c\/li\u003e\n\u003cli\u003eLow ESR electrolytic caps\u003c\/li\u003e\n\u003cli\u003eLow-noise, regulated power supply \u003c\/li\u003e\n\u003cli\u003eGold plated RCA connectors \u003c\/li\u003e\n\u003cli\u003eOriginal Neutrik headphone jack with gold plated contacts \u003c\/li\u003e\n\u003cli\u003eFaceplate and knob available in black, chrome and silver\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Data\u003c\/h3\u003e\n\u003ctable border=\"0.5px\" class=\"table table-striped table-bordered table-responsive;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance:\u003c\/td\u003e\n\u003ctd\u003e47kΩ \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Gain:\u003c\/td\u003e\n\u003ctd\u003e0dB\u003cbr\u003e10dB\u003cbr\u003e18db\u003cbr\u003e20dB (Switchable) \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response:\u003c\/td\u003e\n\u003ctd\u003e10Hz (-0.3dB) to 35kHz (-1dB) \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal-to-Noise:\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;95dB at 0dB Gain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD:\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;0.001% at 6mW (300Ω)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Separation:\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;70dB \/ 10kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Power:\u003c\/td\u003e\n\u003ctd\u003e400 mW (60Ω)\u003cbr\u003e200 mW (300Ω)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Impedance:\u003c\/td\u003e\n\u003ctd\u003eLine-Out: 60Ω\u003cbr\u003ePhones-Out: 5Ω \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption:\u003c\/td\u003e\n\u003ctd\u003e10W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnectors (Audio):\u003c\/td\u003e\n\u003ctd\u003eNeutrik Phone Jacks (6.35mm)\u003cbr\u003e1x Parallel to Line-Out\u003cbr\u003e1x Line-Out Muting\u003cbr\u003eGold-Plated Connectors With Teflon Isolation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions: \u003c\/td\u003e\n\u003ctd\u003e110 x 280 x 50mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight:\u003c\/td\u003e\n\u003ctd\u003e1500g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Lehmann Audio","offers":[{"title":"Black","offer_id":56215761551746,"sku":null,"price":799.0,"currency_code":"GBP","in_stock":true},{"title":"Silver","offer_id":56215761584514,"sku":null,"price":799.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/6652\/0962\/files\/Black-Linear-_2160x2160_4b839eef-b48e-43a5-99c3-34103ff19d7f.jpg?v=1768428871","url":"https:\/\/premiumhomeaudio.co.uk\/products\/lehmann-audio-linear-high-end-headphone-amplifier","provider":"Premium Home Audio","version":"1.0","type":"link"}
