Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements.The Parasound JCM250 is rated at 250 watts RMS into 8-ohms. Parasound provides this wattage at a THD (Total Harmonic Distortion) of 0.15% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 250 watts into 8-ohms (2 Hz-110 kHz) at 0.15%
- 450 watts into 4-ohms
- 120dB Signal to Noise Ratio

Which speakers suit the Parasound JCM250?
250 W into 8 ohms, 450 W into 4, rated down to 1 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
When pairing the Parasound JCM250 with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
What size of room is the Parasound JCM250 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Parasound JCM250 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |

How much power does the Parasound JCM250 have?
The Parasound JCM250 delivers 250 watts into 8 ohms, 450 watts into 4 ohms and 800 watts into 2 ohms, per chassis. This is a monoblock: a stereo system needs two. Its output almost doubles into 4 ohms, which points to a strong power supply that can hold its composure with demanding, low-impedance speakers.
Does the Parasound JCM250 use vacuum tubes?
No. The Parasound JCM250 is a solid-state amplifier - there are no vacuum tubes in it.
What amplifier class is the Parasound JCM250?
The Parasound JCM250 uses a Class A/AB amplifier design. Class A/B is the traditional linear design: it runs warmer and is less efficient than Class D, but it is long valued for its natural, low-distortion sound.
Does the Parasound JCM250 have a built-in DAC?
No. The Parasound JCM250 has no built-in DAC, so a digital source such as a streamer or CD transport needs its own converter, or you connect it over analogue.
Can I connect a turntable to the Parasound JCM250?
No. The Parasound JCM250 has no phono input, so a turntable needs an external phono preamp (or a deck with one built in) before it can be connected.
Does the Parasound JCM250 have Bluetooth?
No. The Parasound JCM250 does not have Bluetooth built in; you would need an external Bluetooth receiver connected to one of its inputs.
Does the Parasound JCM250 have a headphone output?
No. The Parasound JCM250 does not have a headphone output, so headphone listening needs a separate headphone amplifier.
How much does the Parasound JCM250 cost?
The Parasound JCM250 has a manufacturer's list price (MSRP) of $4,250.
