Well the MCACC is downstairs doing it's thing so here's a couple of initial impressions of the 74TXVi.
The 74TXVi appears to only have a pair of 15000 uf capacitors. Which is surprising and disappointing if the 56TXi has a pair of 27000 uf capacitors. Also, on the back of the 74 is states 530w and 690VA, while the 56TXi says 600W and 780VA. The specs do say "Continuous average power output of 140 watts per channel, at 8 ohms, from 20hz to 20,000 hz with no more than 0.09% total harmonic distortion (front). But each channel is rated for 140 watts. I only use the AVR as a pre/pro with 3 Bryston amps so it's not a big deal to me anyway.
The 74 weighs 41.2 lbs as indicated on the box, and the 56 weighs 51.6 lbs as indicated on the box. The difference in weight is appearant.
Another disappointment is that the 74 has a standard lamp grade fixed power cord while the 56 had a beefy heavy duty removable power cord. I also noticed that the 74 uses alot of black screws except on the back panel it uses copper screws, while the 56 used copper screws all over.
Another issue for me is the 12v trigger is a little quirky. Several times after turning it on/off it flashes 12v Trigger Err and won't turn on my Bryston amps.
There are alot more processing modes than the 56 had, but that's expected since the 74 is THX Select 2. PLIIx Game, THX Music, SCi-FI, Musical, Drama, PhonesSurround, etc.
Overall the sound is clean but I did notice some hiss through the speakers that wasn't there before. It's hard to compare the SQ of the 74 to the 56 cause I only use them as pre/pro's and I'm used to hearing my M&K's driven by Bryston's. I used to use the 56 to drive the M&K's and they sounded good, but the Bryston made them sound better since they're relatively hard to drive and power hungry. I'm going to check all my connections and make sure nothings loose and no power cords are next to connectors. I haven't checked out the professional MCACC yet, but the standard MCACC seems to set the channel levels and speaker distance much faster than the 56 did. The 74 adds standing wave correction and it automatically checks/corrects for reverb and EQ Pro in the standard MCACC whereas the 56 seperated those into the Professional MCACC.
I still need to read the manual and tinker around with it but those were some of my first impressions. While they may negative, keep in mind that negatives are usually the first to stand out at you. The exterior is nice looking, typical Elite finish. The OSD is better looking, you can adjust it''s position on the screen and it's much more robust. It's similar to the 56 TXi but doesn't have the Commadore 64 computer look as bad. The remote is smaller and appears busier. I always liked the 56's remote and programmed it to control everything even my dimmer lights. I liked it better than some of the expensive aftermarket remotes. The MCACC microphone is nicer (LOL) and doesn't need that stupid piece of foam to sit straight.
By the way, the operating instructions are universal and they mention a VSX-74TXVi-S and VSX-72TXV-S as well as the VSX-74TXVi and VSX-72TXV. Anyone know what the "S" stands for or difference is? I couldn't find anything in the manual yet.
