Destination Audio 45 monoblock power amplifier

Destination Audio is the realization of company founder Sam Wisniewski’s dream of the sound of the directly heated 45 tube in triode mode. From the creation of the two-chassis 417A tube phono stage to the two-chassis 76 tube-based preamplifier, the 45 tube-based monoblock amplifiers and the Vista horn, the creative objective of all of Sam’s products was to convey the magic of the 45 tube.

Destination Audio is based in Poland. Sam is a self taught designer of speakers and amplifications with no academic background: ‘I have always been in love with the 45 tube and I wanted to create a loudspeaker which is efficient enough for 2 watts to play freely.

Analog Survey, Part 3: Audio Note UK Arm Three/II & IoI Moving-Coil Cartridge Review

By | November 21st, 2018|Categories: Dagogo|Tags: , , |

Listening to high-end vinyl playback means experiencing music recreated collectively by a turntable system and phono stage. Significant changes in the caliber and character of an analog system can very often occur by changing cartridges, as long as is the cartridges are compatible in mass to the tonearm used. To many, this constitutes the most prevalent fun factor of the hobby, and it is unique to the vinyl format, unsurpassed by any other format to this day.

Parts 3 and 4 of this survey will focus on cartridges and tonearms, starting with the 9-inch Audio Note UK Arm Three/II tonearm and IoI (Io “one”) moving-coil cartridge.

By | June 13th, 2018|Categories: Dagogo|Tags: , |

Dr. Roger West and Dr. Dale Ream founded sound Lab on July 1, 1978. Their founding belief was that electrostatic transduction is the optimum loudspeaker technology.

The Sound Lab Ultimate 545, the subject of this review, is the same speaker that Dagogo Senior Reviewer Doug Schroeder reviewed in January 2017, though at the time the product was called the U-4IA. Doug detailed the design and setup aspects of the speakers in his article, so I will focus on my take on the speaker’s performance in this article.
