The A38 is well worth a demo, IMHO it's Arcam's best ever - very detailed, very deep and focussed bass, great soundstage and '3D effect', lively/pacey without being tiring, excellent vocals, and classical/acoustic instruments sound realistic (recording permitting).
IME, approx 120 hours of run-in is needed before the mid-range detail/texture - which is lush - and low-end bass kick-in.
The A38 might've had a luke-warm review from WHF?, but it was 5-star rated by other 'leading hi-fi publications' (UK and international).
