I just bit the bullet and purchased a HK-2700. So much better than the pioneer vsx-1120, bass is alot tighter and fuller. The surround sounds alot better. There is no comparing the HK to the pio. I love my Harman. The ez set/eq got the distances spot on, only had to lower the centre channel level by 2db and raise the satellites by 1db. Plus it set my satellites as large (pioneer did the same). Changed the crossover setting for the 4 jbl 530's to 60Hz and the 520C centre channel to 80Hz with the sub at 80HZ or 60Hz low pass. Still deciding on the best LPF. The studio 5 loudspeakers with the Harman 2700 is a match made in heaven. The Dolby volume is also a nice addition. I had a yamaha rx-v 663 when I first got into home theatre with klipsch speakers. After a while hurt my ears. Loud but didn't like. I sold the yamaha and bought the pioneer. Was alot better, but still found the sound a little bright at higher volumes. The pio was nice for movies, wasn't nice for watching TV. Was alot better when I swapped the klipsch's for the jbl studio 5 series speakers., the sealed subwoofer (550p) is a gem. Heavy 50lb sub and sealed. I am finally happy, couldn't be happier. Would have to spend thousands more to get a better system. Not worth it. I am very happy. I live in a condo, the clarity at low volumes is what I love about the JBL's. With time the JBL studio 5's loosen up and sound even better. Have horn tweeters, but are not bright sounding like klipschs. Clarity at low volumes and loud when tuned up, but don't hurt my ears.
With Harman you pay for the high current amplification, not all of the licensed gimmicks which try to improve the sound. Music, movies, tv all sound spectacular. Harman has a customer for life. I do agree that TV with the dolby volume switched off doesn't sound as good but with it on the sound is to my liking. I wouldn't buy the HK 1700, amp section seems weak.
Forgot to mention: I also love the vtuner internet radio.
