Hi Guys
I've not heard the old Teac Reference 300 Mk111 system so can't compare it to the Ref 380 but I do know that the CD player in the 300 system was not up to the rest of the system. I was tempted to buy one but the negative reports on the CD player put me off. I have had a very good listen to the new TEAC REF 380 system and compared it with the Denon DM37DAB unit. Both systems were played through Dali Lektor 1 speakers. Firstly the REF 380 system costs £500 and and certainly looks the business, very classy and consists of three seperate units mainly, CD player, amplifier and Tuner. It is not currently available any cheaper than £500. The Denon is an all in one unit and obviously doesn't look as substantial as the TEAC system although the build quality is just as good.. The TEAC system outputs 45w per channel compared to 30w per channel for the Denon. There is very little difference between the sound of both these units. The TEAC may sound every so slightly more detailed but I think this is down to the more powerful amplifier being able to drive the speakers better ( recommended amp for Dali's is 40-100w) but the difference is insignificant. The Denon sounds just as good and only costs £175. If you like the looks of the TEAC and can afford £500 then go ahead and buy it. However I would recommend buying the Denon and spending the difference on a good pair of speakers such as the Dali Lektor 1 and you will still have change left over to buy good speaker cable and even stands.I also had a listen with the B&W 685 speakers but they are no match for the Dali Lektors. Hope this helps.
