![]() Once again, an expensive, beautifully designed tube preamp, much like the Vinnie Rossi L2 Signature, honours my LPs and makes my outstanding digital sound like vinyl. It’s a very sophisticated unit that sprinkles life, musicality and the most incredible dynamics on everything it touches. But the sound is far above that mundane visual description. The look is industrial and solid, with beautiful casework and those sexy tube chimneys. The L-7000 is an ultra musical device that works flawlessly-Allnic’s tube gear I’ve reviewed works as effortlessly as my top class solid state kit. Serious listening after break-in garnered serious results. Power Consumption: 30W at 110/120V / 60 Hz. ![]() Frequency Range: 20Hz ~ 20kHz (FLAT) 16Hz ~ 50kHz (-3dB). ![]() Input Impedance: Unbalanced 10kΩ Balanced 10kΩ.Ultra high speed, automatic, vacuum tube voltage regulation.Constant and low (150 OHM) output impedance at all frequencies.Only the chassis, attenuator control and the AC power connection are shared) True Dual-Mono design (the two channels operate completely independently of each other.Other features of the Allnic Audio L-7000 As such, the system was hot and heavy and ready to go for my standard weekday afternoon review listening sessions. My Jeff Rowland amplifier is on full time as are my Mytek HiFi Manhattan DAC II and Antipodes Audio CORE Music Server. Standard operating procedure chez nous: turn on all tube and turntable components after breakfast and turn off last thing at night. The fifty hours cleared things up a little from an already wonderful out-of-the-box experience, but an additional 25 hours took the L-7000’s performance into dreamtime. Repertoire was divided almost equally between digital files/streaming and vinyl. Hanging a beefy Allnic Audio ZL-3000 Power Cable ($1400/metre) off the side garnered positive audio results while making a visual statement.Īfter about fifty hours of burn in, I began serious auditioning. Allnic Audio’s manual suggests upgrading the cable commensurate with the price and quality of the L-7000. Not ideal for my aesthetic (a real estate decision, according to Beetles), but Allnic provides a right angle IEC power cord which lessens the visual impact. The power socket is on the left side of the unit. Shipped tubes include: E810F × 2 (gain stage, left and right channels-Mullard NOS) 300B × 2 (Voltage Regulator) 5654 (similar to EF95, 6AK5) × 2 (Voltage Error Detector). Good solid handles on the chassis and handles cut into the shipping box help with lifting.Īn Allen key is provided to remove the tops of the tube chimneys to take out the protective shipping materials and to remove the back plate of the remote control to insert 2 AAA batteries (not supplied). Lift with your knees and watch your backs. Unboxing is easy but should really be a two person job. Weighing in at 18 kg with dimensions of 430mm (W) 410mm (D) 173mm (H). I’m not sure if any major designer has reversed the roles for such a superstar tube. The L-7000 audition should be interesting. I recently finished a review of a superb $16,995 linestage, the Vinnie Rossi L2 Signature Preamplifier-a component that projects music to the heavens via two 300Bs, both, most definitely, in the audio chain. The benefit the 300B brings to as a voltage regulator is its ability to pass a fair amount of current at low cathode-to-plate voltages. But it will take some rethinking to imagine this great tube in a non-audio role. The 300B has justly won the reputation for being a superb output tube in single-ended amplifiers. ![]() But, to shake things up completely, designer Kang Su Park uses the much-loved DHT 300B tube, not in the audio chain, but in the power supply chain as a voltage regulator. It is a single gain stage unit and is transformer coupled. The L-7000 is not your grandpappy’s 300B tube linestage preamp. After my continuing musical experiences of the most passionate and intense kind with Allnic’s similarly priced H-7000 Phono Stage, how could I pass up the opportunity to hear Allnic’s linestage equivalent? David Beetles of Hammertone Audio, the North American distributor for Allnic Audio electronics, gave me a nod that an L-7000 Preamplifier was available for review.
