Hafler
P3100 150W 2-Channel Studio Power Amplifier
Additional Photos:
- Patented Trans Nova technology with lateral MOSFET output topology
- 150 watts per channel into 8 Ohms (200 w/channel in 4 Ohms)
- Ultra quiet performance with toroidal transformer and oversized heatsinks
- Ideally suited for audiophile and professional studio recording
Inside the P3100 is the latest refinement of the Trans*Nova (TRANSconductance Nodal Voltage Amplifier) circuit that was developed by industry guru Jim Strickland. The Trans*Nova circuit squeezes the most out of every component to reduce the gain stages down to three in lieu of the five typically employed by others. The shorter path results in a much more open sounding and realistic sound stage.
In this latest iteration, a toroidal power transformer has been introduced. This has a lower output impedance and produces far less noise than a conventional E-lam transformer. The result is a tighter, more defined bottom end. As well, toroidal transformers are inherently self-shielding which reduces the amount of potential low frequency and rectifier noise introduced into the audio signal path. Passive convection cooling, with over-sized heatsinks, surround the amplifier eliminating the need for a fan, thus enabling the P3100 to be used in the most intimate installations. The front panel includes individual level adjustments to offset room imbalances, signal present and ballistic LED metering, along with indicators for faults due to excessive heat or short circuits. A soft start power-on switch protects loudspeakers from turn on transients that could reduce lifespan. The rear panel sports a choice of XLR, TRS and gold plated RCAs for greater flexibility. Output connections feature gold-plated binding posts that can adapt to all popular speaker cable sizes.
In use, the Hafler P3100 is rich in detail, depth of field and musicality. With 150 watts of available power per channel at 8 Ohms and 200 watts at 4 Ohms, the P3100 has plenty of headroom to drive the most power-hungry loudspeaker. Bridged in mono, 400 watts are available for sub-woofers or as a matched pair for larger 2-channel setups.

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
- USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
