The Serene Pre-Amp is here!
Currently production time is estimated for about 5-6 weeks from time you place your order. We appreciate your patience and understanding. We will likely deliver before this time, but this is an estimate for new orders. Inventory shown on the website is to control sales volume only.
Here at Kitsune HiFi, we have two build specs. of the Serene Preamp.
Prices are as follows for Serene lineup:
Serene (standard model) = $2698.00 + S&H
KTE Serene = $ 3098.00 + S&H
As of April 2020 shipping costs on all HOLO Audio products have gone up significantly due to COVID19. This is out of our control.
Serene Product Description:
A new generation of fully discrete preamplifiers.
- The Serene “晴” adopts a true and fully-balanced design from end to end, with 4 sets of channels, left and right channels each form a fully-discrete design, each channel has two fully-discrete and separate amplification modules to complete buffering and amplification (attenuation) functions. For a total of 8 amplification modules.
- The 8 amplification modules of Serene “晴” are of a fully discrete design. The shortcomings of the transistor itself are solved through structural design and implementation. Its tone can exceed the limitations of traditional transistors. Using significant amounts of paired transistors delivers superior linearity and also has the advantages of electron tubes and transistors at the same time. Its tone can exceed the limitations of traditional
- Serene’s “晴” power supply is a completely independent structure from the secondary transformer. This is a dual mono amplifier placed in a chassis, so it has a full frequency >130dB performance of channel separation, so that the sound field is perfectly reproduced.
- Serene “晴” volume control is a fully balanced stepping device controlled by relay-controlled gain stage. Relays are the finest quality with Silver Palladium (AgPd) Gold Plated contacts. For a total of 84 steps, each step is 1db volume, and provides a volume control from -78dB to +6dB. Its advantage is that it has ultra low noise and can be accurately controlled at low volume without causing the phenomenon of left and right channels having unmatched levels. The matching degree of left and right channels in all volume ranges are within +/-0.1dB.
Serene L1(Standard) and L2(KTE):
Standard Model includes:
- 7N copper, round wire O-type transformer, which was used in the Spring 2 (non-KTE)
- Standard copper hook-up wire

WARRANTY – 3 years warranty, both parts and labor, coverage of one way shipping (return shipping at cost to seller once product is confirmed as a warranty claim issue). Be sure to buy directly from HoloAudio or authorized reseller, we recommend purchasing from HoloAudioUSA<– this is KitsuneHiFi 😉 – Support is given from where you choose to purchase.
This is special order item (will show “in stock” if able to order, this means we have the parts available for this Pre-Amp. and the order can be placed), expect a typical 5 – 6 weeks (estimated) delivery time to USA customers.
( Items listed in-stock are NOT ready to ship, this means we have enough components on hand to build them)
We are working our best to keep up with demand. You will get estimated time for production and shipping with your order.
We will give you a current estimate upon receipt of payment, if it is different than standard production time, as this is considered a special order item there will be no cancellations or refunds if 48 hours past date of order placement.
