The T+A Cala is an all-in-one with 55W amp, FM Tuner, USB, BlueTooth and UPnP streamer with iOS controller app. No mention of gapless playback, FLAC streaming but not clear to what bitrate. £1499.
According to the manual it does gapless and can stream at 24/96 max. The bluetooth is only a basic AD2P and not APTx and for the price I would have expected a digital input. It is pricey!
