The reason I got the Denon AVR-5308 was because I told myself I would simplify things and just get a single-box solution.
And now I will be using the AVR-5308 as a preamp for my 2Ch Direct mode music listening.
The actual 3rd party (HTM) measured spec for the AVR-5308 is FR 20Hz-20kHz +/- 0.0dB, SNR 110dB, Crosstalk -92dB, THD 0.004%.
Following are published specs in the 7005's manual, not 3rd party tested yet:
Audio section
• Analog
Frequency response: 10 Hz – 100 kHz — +1, –3 dB (DIRECT mode)
S/N: 105 dB (IHF–A weighted, DIRECT mode)
Distortion: 0.005 % (20 Hz ~ 20 kHz) (DIRECT mode)
• Digital
Total harmonic distortion — 0.008 % (1 kHz, at 0 dB)
S/N ratio — 102 dB
Dynamic range — 100 dB
Digital input: Format — Digital audio interface
This is just preamp, then you have to factor the power amp into the equation (additional THD, noise etc.):
MM7055
Rated power output
(from 20 Hz to 20 kHz/THD = 0.08 %,
two channels driven):
140 W/ch, 8 Ω
170 W/ch, 6 Ω
Maximum effective output power
(from 1 kHz, two channels driven):
210 W/ch, 6 Ω
Output bandwidth (8 Ω load, 0.09 %): 5 Hz – 40 kHz
Frequency response (1 W, 8 Ω): 8 Hz – 100 kHz (±3 dB)
Damping factor: 100
Input sensitivity/impedance: 1.2 V / 22 kΩ (UNBALANCED)
2.4 V / 30 kΩ (BALANCED)
Signal-to-noise ratio (IHF-A): 105 dB
Looking at these numbers I am probably going to hold on to my 4308 (also as preamp for 2 channel) a little longer and may be wait for the 4811. I will not go further than that though as I know my hearing sense is not above average.
In your case I think you can spend all kinds of money to acquire new gear but in the end you will end up with things that are nice to look at, fun to play with, but your ears may not know the difference.
