T O P I C    R E V I E W Perfect Sense Posted - 2014/04/19 : 16:27:14 Aesthetix erbjuder nu en omfattande uppgradering av sin mycket kompetenta CD/DAC Romulus till Signature-status. Uppgraderingen innebär förutom äkta DSD-stöd en ny analogdel, förfinade komponentval samt avancerad resonanshantering ifrån en av de ledande aktörerna inom området - HRS. Uppgraderingen finns även tillgänglig för den renodlade DAC:n Pandora. Vår uppgraderade enhet är på plats inom kort för demonstration och hemlån. Vi förväntar oss ett märkbart lyft ifrån en av marknadens mest analogt klingande och musikaliskt tillfredsställande signalkällor. The Absolute Sound har nyligen testat Romulus - "A giant-killer": http://www.theabsolutesound.com/articles/a...s-cd-playerdac/ Läs mer om Aesthetix: http://www.perfect-sense.se/varumarken/aesthetix Vårt fullständiga utbud: http://www.perfect-sense.se/varumarken Aesthetix beskriver själva uppgraderingen såhär: "Aesthetix Romulus and Pandora are now available in a Signature version. Existing Romulus and Pandora units are factory upgradable to Signature. True Native DSD Romulus and Pandora Signature offer true native DSD 1x and 2x functionality over USB and 1x DSD over SPDIF (AES/EBU, RCA Coax and TosLink). The entire DSP processing section is replaced (pictured above, click to enlarge). The new section includes an advanced Xilinx gate-array which allows the DSP to be completely bypassed for pure DSD 1x and 2x operation. No alteration of DSD data occurs. Many DACs in the market that claim to play DSD actually convert the data to PCM and thereby completely lose the purpose of DSD operation. Vishay Z-Foil Resistors In addition to the DSP processing section, an entirely new analog board is installed (pictured above, click to enlarge). This new analog board also allows DSD data to pass directly to the DAC, a Burr-Brown PCM1792A running in pure differential mode. Extremely low noise, high linearity Vishay Z-foil audio resistors are utilized in the critical current-to-voltage conversion stage (pictured above, click to enlarge). Dynamicaps As in all Saturn Signature products, critical coupling capacitors are replaced with Dynamicaps from Peter Moncrief. Four are installed between the vacuum-tube gain stage and output stage, all in full differential mode. These provide increased resolution, less grain, greater high frequency extension and naturalness, all while maintaining the basic strengths of Romulus? tonal balance. The eight 2uF output capacitors are replaced with 4uF Dynamicaps which provide greater resolution in addition to improved bass definition, drive and dynamics. (pictured above, click to enlarge). HRS Couplers The four standard rubber feet are replaced with Harmonic Resolutions Systems' Nimbus Couplers specially made for Aesthetix. This change lowers the noise floor and adds more air and space."
