Blue Aura VA-30 Blackline Integrated Tube Amplifier

The amp is 10 inches wide, 7.5 inches deep and 5.5 inches tall, and the plated handles on either side of it double nicely as bookends.  Adorning the front panel is a pair of matching chrome knobs—one for adjusting the volume and one for selecting from the three inputs (USB, LINE, and AUX).  Two 6N1 tubes flank the taller 6e2 tube, with its decorative but unnecessary green glowing light filter.  A four-post tube guard with a plexiglass-and-chrome top shelf protects the tubes from inadvertent fingers or the common office mishap.  On the back panel, from left to right, are three inputs (RCA, mini-headphone, and mini-USB B), followed by a mini-headphone output jack, four brass speaker jacks, the power-cord socket and power switch.

It’s obvious that the Blue Aura engineers understood that the typical home-office setup limits how far apart speakers can be placed.  The result is a nice, expansive soundstage and subsequent enjoyable listening experience.  Even stepping down to my MacBook’s analog output and running a wire to the v30 yields worthwhile results.

The system excels at reproducing jazz music, and quickly makes Vince Guaraldi’s classic Charlie Brown Christmas a playlist favorite.  The v30’s ability to recreate the individual bass notes in “O Tannenbaum” bests the budget bookshelf speakers that normally occupy my office—and those are more than three times the size of the v30’s speakers.  Guaraldi’s piano matches the glow that the three tubes adds to the keystrokes.  The slight loss in absolute detail is easily made up by the system’s warmth and rich decay.
