Hi guys, here is a cut and paste of a question I had put out on the 2060 pages - it was suggested I redirect it to this thread as the AVR's have changed slightly. I will begin off the hop that folks in the 2060 believe my problem is that I have continued the speaker configuration of my DefTech built in subs being connected through the speaker wires and using the internal line-level adapters rather than using LFE and separate cables. Although I am open to the idea of experimenting with connecting cables instead (I would still have to go out and buy some before I can do this), I say that I have used this configuration with 2 Yamaha AVR's before it and they always sounded amazing. Also, both DefTech and other DefTech users also state connecting the subs in this manner usually yields the best results. Having said this, the original question is below:
HELP! I just spent over 15 hours in my theatre trying to make a used upgrade to RX-A2070 work for me from my prior RX-V1075. After 3 days of messing around and adjusting almost anything I could adjust, both my wife and I unanimously agree that the old one sounded better! Reasons for upgrade: could not pass through video because of HDCP2.0 on the RXV - and I thought Atmos/DTS-X would be nice.
Reasons for disappointment: found that sound was tinny and high, somewhat hollow compared to the RX-V. RX-V sounded noticeably fuller with more bass (but not exaggerated)
It got to a point while watching a DD5.1 bond film last night that even though the voices were at a reasonable level, there was ear shattering high pitch response with a severe lack of low-end to balance it. We both had headaches after the movie even though it wasn't actually loud as far as overall sound pressure. Whenever there was gunfire or shattering glass we would cringe in our seats! When there was an explosion, it had almost no sonic impact at all - like someone had taken an equalizer and lowered all frequencies between 20-500Hz. I went back to the RX-V this morning and brought my wife down, she confirmed animatedly that it sounded better than last night.
I messed with DSPs, eliminated the new front presence speakers I had spent a day installing because of the extra 2 channels available, messed with the auto and manual speaker set up, adjusted other sound settings in the options panel such as extra bass and also cranked the sub on my DefTech speakers to near the max. 15+ hours messing with it! It's really strange because when going through all the channels with a SPL meter, all were balanced between 26Hz to 18000Hz, so I figure it's just the mapping of the sound in the unit. I cannot believe that this makes any sense, why would a 6 year old flagship RX-V sound better than a 2 year old high end RX-A? I read one single thread somewhere that someone claimed the RX-A2060 sounded better than the replacement RX-A2070 but found no other single mention of this being the case after scouring the internet. I really need help rectifying this problem as I'm well over $1100 in the hole now and I may loose money on the 2070 if I try to sell it right now. Plus I really want to make the 2070 work due to the fact it's got all the features I want and need for HDCP 2.2 and my other equipment.
I tried fiddling away from default with things like adaptive DRC, YPAO volume, virtual speakers - no improvement. I removed the newly installed front presence speakers and re-ran YPAO - no improvement. Manually set everything that I felt was inaccurate in the setup - no improvement. I even tried manually cranking my DefTech subs to near max and added the extra bass in the options menu, improved but still hollow, distant and flat sounding. I must have switched AVR's back and forth over 15 times as fast as possible, and my RX-V which only ever had a quick YPAO setup was noticeably improved (if my wife could tell the difference, it must have been horrendous as she is tone deaf).
There is nothing I can imagine that would make any improvement at this point, it almost seems like.....the AVR simply is having some issue outputting low frequency information with the source material. I used a SPL meter and test disk though, and found response pretty flat between 32Hz (it's as low as my test disk goes) to 18kHz using "C" weighted which seems to be industry standard. I did run a check using "A" weighted which is supposed to be what the human ear hears, there is a slight dip in SPL under 240Hz but no different than the RX-V. In fact the 2070 seems to be miraculous as getting what used to be about 4 or 5db difference in some speakers (parametric EQ set to through when checking for baseline reference) to nearly identical SPL on all speakers with parametric EQ set to flat. YPAO seemed to be excellent overall where I could tell, speaker distances/size/crossovers slightly more accurate than the RX-V.
AVR (mode 1), Parametric EQ (flat), Speakers all DefTech matched set, DefTech subs connected with speaker wire not cables, Panasonic DP-UB820 (any disk I tried both BR and DVD), tried 3 different disks including DD 5.1 media, Standard default "power amp assign" (main zone 9 channel), no separate zones used or connected, surround mode (straight), front center and sides (full signal), rear surround (tried 80-110Hz crossover).
