The Red Priest ( Vivaldi )

A terrific line all tube preamplifier fitted with NOS Philips ECC186SQ as voltage amplifier and 5687 for low impedance high current output buffer. Power supply is a fine all tube Shunt Regulator. ECC186SQ is the best ECC82 family tube ever made. The crucial mid range ( male/female voices ) is astouning but unfortunately …this tube now It’s very expensive !! All capacitors are MKP or Paper in oil, carbon composite resistors in the signal path,…

Madama Butterfly 2A3 SE Power Amplifier

Another 2A3 SE amp !!!! oh no !!!! What in the added value in my implementation? What I present in this blog is the result of many, many….. hours of listening sessions to various configurations and components about a SE class A 2A3 Amplifier. My target was the best design to reproduce the body, sonic texture and fine gradation characteristic of natural sound. This is what, in my opinion, is the best result in terms…

DUAL 1019 Naked

The Dual 1019 without doubt is one of few finest turntable ever built. It first began production in 1965 and is a fully-auto, idler driven with integral tonearm and pitch control and heavy massive platter ( 3.4 kg ). The mechanics are outstanding… This electromechanical masterpiece justify the adoption of a marble throne… On the bottom base of 430×375 mm and 20 mm thickness yellow egyptian marble are screwed three 80 mm height solid wood…

K2 Klipschorn (super) klone…

This is my reference speakers…… I heard hundreds of speaker systems but at last….I always return at my Klipschorn super clone. Why super ? OK bass bin is almost identical to original Klipschorn, also fitted with original K33E Klipsch woofer but mid-high section is very different.     I use high-end expensive component like Gauss HF4000 as midrange assembled with JBL 2350 aluminum horn. Gauss HF4000 2”compression drivers are very impressive components: heavy (13 Kg…

Sheherazade DSD-PCM Sabre32 DAC

This is the ”reference” DAC in my audio system. It’s based on Twisted Pear Audio (http://www.twistedpearaudio.com/landing.aspx ) Buffalo III SE board and consist in my implementation for best use this module. The heart of Buffalo III board is the ES 9018 ESS Sabre32 Reference DAC chip. Whith its amazing performance is probably the best DAC actually available. It can handle 32 bit PCM data via I2S input as well as DSD or SPDIF data with…

Falstaff Hybrid Circlotron Power Amplifier

     ‭ ‬ There has been considerable debate over the characteristics of tubes versus transistors…..The goal of this hybrid power amplifier is to take advantage of best performance of both technologies tubes and solid state device.‭ ‬Tube is highly linear without negative feedback,‭ ‬smooth clipping,‭ ‬wider dynamic range,‭ ‬characteristics highly independent of temperature,‭ ‬and so on‭…‬but its disadvantages such high-impedance devices that usually need a matching transformer for low impedance speakers.‭ ‬I prefer to…
