Question

JVC RX-DP10vbk vs Mcintosh MC58

Mar 5, 2015 5:37AM PST

What kinds of volume lose will I notice if I go from my JVC RX-DP10vbk to the Mcintosh MC58?
I understand the difference in sound quality, I want to know if I will get decent volume.
I currently have the JVC receiver driving a pair of Infinity SM 150 speakers.
The highest that I think I have turned the JVC up to is about -18DB.
The specs for the two amps and the speakers are listed below.
JVC RX-DP10VBK specs:
120 watts x 2 min. RMS, both channels driven into 8 ohms from 20Hz to 20kHz with no more than 0.02% THD, 120 Watts x 2 min. RMS, driven into 4 ohms, with no more than 0.07% THD. 4 ohm Rated (FTC)
120 watts x 7 min. (2 Front, 1 Center, 2 Rear speakers) RMS, into 8 ohms, 1kHz, 0.2/0.7% THD
Infinity SM 150 Speaker specs
Bass: 1 x 15 in. (38.1 cm) polypropylene coated woofer
Mids: 2 x 4.5 in. (11.4 cm) dome polypropylene coated midranges
Highs: 1 x 1 in. (2.5 cm) dome polycell tweeter
Suggested for amplifiers with: 10-300 Watts per channel
Frequency range: 44 Hz - 25 kHz
Crossover frequencies: 500 Hz, 5500 Hz
Sensitivity: 102 dB
Impedance: 8 Ohms
The Mcintosh MC58 Specs
Power Output Per Channel
50 watts into 4 ohm load and 30 watts into 8 ohm load is
the minimum sine wave continuous average power output
per channel, all channels operating.
Power Output Bridged
100 watts into 8 ohm load is the minimum sine wave continuous
average power output per channel, all channels operating. Total Harmonic Distortion

Answer
100 vs 120 RMS- about the same

Do a side by side. It should be similar with those two RMS figures.

Keep in mind that what constitutes 'decent volume' is quite subjective.

JVC RX-DP10vbk vs Mcintosh MC58
Mar 6, 2015 1:37AM PST

Thank you for the reply. I understand that if I run the McIntosh at 5 channels bridged, I can get 100 watts. What I want to do is run at least 7 channels. To run 7 channels, I would have to run the McIntosh unbridged at 50 watts. I know that RMS watt's are rated slightly different from one manufacture to another and I am assuming that McIntosh is on the conservative side. I also understand that THD figures into the equation. So the JVC is rated at 120 watts at .02 THD while the McIntosh is rated at 50 watts at .005. So I guess, what I am asking is how will the McIntosh stack up against the JVC. I am assuming that I will lose about 3db's.

I would stick to the manual

Specs rather than name brand

I understand the McIntosh rep over the JCV rep and if they were comparable I would go with the Mac. But the JVC receiver I have is the flagship receiver and it has served me very well as far as power, sound quality and clarity. I have read numerous favorable reviews including a reviewer that favored the JVC over his carver. Now if I go by the manual as you suggested which I already had a copy of, then through my 8 ohm speakers I am only getting 30 watts. I had a McIntosh system at one time that had 2 MC60 tube amps. That system at 60 watts would rattle the house. So at 60 watts the MC60 produced as much if not more volume than the JVC I have now. So I am asking if the MC-58 will pump as much volume per watt as the older Macs did. I have a chance to buy a MC-58 with a MX 135 for a steel but if I can get the power to drive my speakers then it doesn't do me any good regardless of the increased quality of sound.

Bridge mode vs stereo mode
Mar 9, 2015 2:29PM PDT

But I thought you were looking at bridge mode? That says 100watts. Maybe we are speaking two different languages here. I'd suggest perusing AVS forum to clarify what you might expect w/ the McIntosh vs your flagship.

Keep in mind running two separate amps ("bi-amping") almost always trumps anything a single amp is capable of in bridged mode. IOW, what you should expect from running two McIntoshes would naturally be a powerhouse vs a Mc58.
