you say it can be had for 800 GBP now? nice 🙂 when I bought it last year it was priced at 1000 GBP. fast price drop.
anyway I decided to shed some light on my experience with the Reference 600 and hopefuly help you out with making the right decision. BTW it's my first post on WHF forum...
so, to the point. I bought my Reference 600 in January last year. I based my decision mainly on WHF's review. it was my first plunge into the world of hi-fi. before that I only listened to music from my laptop+Creative X-Fi sound card+ Creative 2.1 speakers. I had a chance to audition Teac's system with various speakers. at first I wanted to buy it with MA RX6 but as I was short with cash I setteld to buy rather cheap Wharfedale Diamond 10.1 having in view buying something better whenever I got a chance. in the end it turned out to be a great coincidence becouse I had more time to decide on speakers and my eyes lied on Dynaudio. I eventualy bought Focuses 110. it was one of the best decisions in my life, great little-big speakers (but now I'm running a little bit ahead of myself). for about 8 months I was playing Reference 600 with Diamonds and it was time spent very pleasurably. as I said befere, it was my first hi-fi so I new little about typical traits of true hi-fi; like soundstaging, imaging, timing and tempo, accuracy, reflecting true timbre of instruments and so on. now I know that then I had hardly any sounstage depth, hardly any imaging and presentation was rather sluggish and slow. after 8 months, as I mentioned befere,I upgraded speakers to Dynaudio Focus 110 and suddenly everything began to sound so wrong to a degree that I was forcing myself to listening to some music only to justify the fact that I payed a lot of money for the rig! what was immediately most annoying was a great deal of sibilance which began to polute my music. it felt as if some nasty hissing worm was draging behing leading notes all the time when someone was singing. and percussion was too splashy as well. I began to think that the speakers are too revealing of the amp because they couldn't be so bad if they were so well regarded wordwide! even though it wasn't my intention back in January I decided to upgrade the amp. after extensive reading I settled for Pathos Classic One mk3 (besides I got a very good deal on ex-demo unit 🙂 ). unfortunately I din't have a chance to audition the amp. I bought it only on my expectation based on opinions expressed in reviews. when it finally came I noticed right away a great improvement in sound clarity. heavily dence tunes suddenly started to sound much more organised an not so confused and homogenous, i.e. Sigur Ros's "Saeglopur" from album "Takk...". and big dynamic swings were waaaayyyy better described. the sibilance not so much dissapeared but I was so much happy with the change that I also decided after a couple of more months to upgrade the CDP to matching Pathos Digit (I didn't audition it as well and yet again I got a nice ex-demo deal). so in January after a mere year I got a completely new hi-fi setup but I was never ready for what was about to come. introduction of Digit changed considerably presentation. the sound is now very fast and precise, imaging is wonderful (especially in recordings of live music like jazz or classical) but what amazes me most is the ability of this CDP to retrieve and transfer background details; therefore micro dynamics is wonderful, small nuances in reverberation and decay of instruments make you believe the experience is more alive, not to mention the depth of soundstage which expanded hugely! as for dreaded sibilance; it finally vanished but not before I changed the speaker cable from silver plated copper Qued Revelation to pure copper Atlas Hyper 2.0 (but that is a different story).
so summing it up. I wouldn't reccomend you Teac Reference 600 mainly on the grounds that you like to listen rock. it may be too slow responding for fast paced music and its inability to controll deep bass makes things only worse. if I were to recommend you anything I would suggest you, based on my experience, to save for a little bit longer and get yourself something more decent. you may like Naim Unity. it's an all-in-one (so not too many boxes), it does everything you could possibly want at this point in history of mankind and it's fitted with a decent amp + CDP. I must admit I haven't heard it in action but you can find some very favourable reviews around and you can hardly find any ill word on Naim gear from their users. IMO definitely worth audition. I hope this helps although I know what you think now: wiseguy, it's always easy saying someone to dish out more dough 🙂 . but then again you must answer youself a question how much hi-fi you really want and need.
good luck
