Advance Acoustic MAP305DA II amplifier [ Review ]“With the amp warmed up, it kicks off in alively, upfront style that’s high on vitality,if a little short on sophistication.”might benefit components placed above andbelow it on an equipment rack.The on-board DAC is specified as being a24/192 device that should work with mostcomponents, including DVD-A players that canoutput 24/96 bitstreams. Surprisingly, givenAdvance Acoustic’s enthusiasm for the iPod,there is no mini-jack input.PERFORMANCEAll of the MAP305DA II’s inputs are accessiblefrom a metal remote handset. The remote’saesthetics are only slightly undermined by alack of volume control subtlety; you have tohave a very delicate touch to initiate anythingless than a significant change in level. It alsoseems to have rather a lot of gain, and evenwith our least sensitive speakers, there wasn’ta lot of range available on the rotary control– which is partly why it’s difficult to initiatesmall changes with the remote.With the amp set up and warmed up, it kicksoff in a lively, upfront style that’s high onvitality, if a little short on sophistication. Thisvia the taxing load offered by a pair of B&W802D loudspeakers, which are, perhaps, rathertoo revealing for an amp of this price. With theCambridge Audio 840A in its place, there’s afuller and more detailed sound, albeit one thatdoesn’t offer any more control in the bass, and,if anything, gives a slightly less comfortablebalance at high levels.A slightly more appropriate speaker – in theform of the ATC SCM19 – suits the AdvanceAcoustic’s bass rather better. The ATC SCM19doesn’t extend as far as the 802D and, as aresult, the sound is tight and tuneful, althoughit does reveal a degree of hardness throughthe midrange. The 840A proves rather morenatural in this area and more detailed asbefore, but it does cost another £150.The Pioneer A-A9 integrated, on the otherhand, is a precise price match, and one thatdelivers greater bass weight (for a lowerspecified power), but doesn’t match theAdvance Acoustic’s resolve through themidrange, or its precision.The MAP305DA II does not have thesmoothest of top ends and we wonder if theaforementioned footplates could help as theycome with stick-on rubber pucks. Placing thisdamped interface between the TownshendVSS (glass shelf) rack and the amp does seemto smooth out the top a little, however.Using the digital input and on-board DAC witha Pioneer PD-D6 CD player produces a calmerand more relaxed sound than the player’sanalogue signal, but does result in a reductionof low-level detail. Remember, however, thatthis is a pretty new CD player with a decentsound and not one that is easy to improveupon. Rega’s superb Apollo CD player deliversa more sparkly and open balance via theAdvance Acoustic’s converter, but loses theappealingly analogue quality that it usuallyoffers. In both instances the amp’s slightlyforward character is more obviously notablevia the digital input.Given that the ATCs are still, perhaps, a littleon the expensive (and revealing) side for anamp at this price, we figured the B&W 683could do better. They immediately bring outthe fulsome brassy sound of Ornette Coleman’sChange of the Century and add some mostwelcome bottom-end too. Just out of curiosity,we also put Cambridge’s 740A integrated ampup for comparison. For its £100 saving over theAdvance Acoustic, it delivers a more tautand precise sound with greater bottom-endsolidity, but a degree of dryness that suckedsome of the life out of brass instruments.The MAP305DA II is a remarkablycompetitive amplifier that offers a superbrange of features for the money, not forgettingthe D/A conversion. It’s dynamic and looksinherently more expensive than it actually is.Something of a bargain, then.
