Some thoughts from last night while listening to the Audio Mirror D-1 in comparison to the Ack! 1.3 and Nixon TubeDAC+.
Timing: Audio Mirror and Ack! agile to tempo changes; Nixon slow in bass and treble.
Sweep: Audio Mirror and Ack! convey the sweep of orchestral strings, from bass to violin; Nixon makes for violins here, cellos there.
Bass: Audio Mirror by far the most prodigious bass, this rocks; Ack!, a quick bass; Nixon vague and soft, nice jazz bass.
Mids: Audio Mirror good tonal color in midrange; Ack! never comes alive here, very distant; Nixon lovely, round, 3D, liquid, dynamic.
Highs: Audio Mirror treble has detail, yet allows bad recording to be listenable; Ack! very delicate, sweet, detailed; Nixon coarse.
Dynamic Life: Audio Mirror dynamics blossom like spring flowers; Ack! wafts like floral scent; Nixon dynamics like biting into a juicey mango.
Clarity: Audio Mirror color like clear spring sky; Ack! snow melting winter sky; Nixon summery hot and humid sky.
Liquidity: Audio Mirror liquid like a fine wine savored; Ack! an Apollonian tea ceremony; Nixon Dionysian celebration.
Depth: Audio Mirror wilderness landscape; Ack! urban angular landscape; Nixon round portrait intimate.
Height: Audio Mirror floor to ceiling; Ack! speakers; Nixon wide to side walls, just above speakers.
Ack! dAck! 1.2 & 1.3; Nixon TubeDAC+ with dozen & 1/2 tube trials. Amps: Decware; Consonance PP 2a3; Cayin A30; various chip amps, Shigaraki and Gainclones; Transports: Sony DVP-s7700 & s7000; Shigaraki. Speakers alway Jordan JX92S fullrange singles.
