The new Q Acoustics 5050…….. is a significant power improvement on the musically involving 5040. It’s a ‘big-boy’ speaker. Big stage, big dynamics and deep bass with potent presence and projected power. If you haven’t experienced ‘projection of power’ try the 5050. We are a Q Acoustics dealer.

OUR NEW M4 AND M8 COMPLETE DRIVER BOARDS….. with all new MOSFETS work great in the Hafler SE-100/PRO 1200 too. Double-Die, high current mosfets can be used for speakers needing more oomph.

For more power: PA-8, 6 mosfets/channel

is the default Hafler SE-240/PRO 2400 replacement. The PA-8.8, 8 fets/ch, works great in the SE-240/PRO 2400 for hungry speakers. Link soon. Send any of these models for introductory pricing now. New power supply work required. Kit in planning stages. PRO versions often available at nice prices.(12-01-23)

YES THERE IS A PA-7.3……… In these modern times we all know this type nomenclature/titling - Something.improved. Okay that’s the case here too. PA-7.3 is ready in kit and installed versions. It’s much simpler to install, sounds better and priced the same as the PA-7 V2, but the V2 is now discounted. (08-14-23)

WE HAVE A NEW CAPACITOR ……….. for our  LC-500 mod that boasts 36,000uF/100V of modern capacitor performance. They have excellent performance and long life in the large Adcom, B&K and Hafler amps. Size is 2.5 dia x 5.5” high.  They come in at $199/pr in kit.

WE HAVE MODIFIED THE FIRST B&K ST-140 AMP….. with the new PA-8BKS board and the results are excellent in every way. The ST-140 board is available installed for now - kit later. While the ST-140 has both channels on one board the ST-202 needs a different pair of mono boards, the PA-8BKM pair. These ST-202 boards are ready now.  You’ve never heard a B&K like this. New stereo driver board pictured below with PS-500SE power supply. Sweet sound indeed.  (12-07-22)

NEW SUPERB B&K AMP UPGRADE…..with new PC board replacements are here. These are all new for us. They owe their creation to the PA-7/8 modifications. They bring the exciting improvements available to Hafler owners so B&K owners can smile anew. We no longer have to tell B&K owners to get a Hafler if they want our best of our mods.

These are for amps with the ‘plastic’ TO-3P style transistors. The earlier B&K amps with the full metal can mosfets will eventually be addressed too. We welcome your comments on those early amps. As information becomes available you will see details on the B&K amp page.  (11-11-23)

Recent feedback…..

“Absolutely amazing. Day and night difference. The sound is outstanding.” DH-500 with PA-7 Elite & PS-500 V2B, David S., FL

 

NEW MUSICAL DESIGN AMPLIFIER…. new M4 power amplifier.

FEATURES:

• Beautiful engraved front panel
• Laser etched rear panel “silk screen”
• Robust multi-shielded toroid power transformer-Quiet
• 12 Audio-Grade power supply caps reduces power supply impedance - better ‘punch’
• Dual-Mono mode, 8 ultra-fast rectifiers, low noise/black background, 3D staging and true-to-life “you are there dynamics”
• M4 features excellent sounding ‘Dual-Die’ MOSFETS - doubles the driving ability vs single pair of device
• M4 has our ear-tested Premium resistors/capacitors
• M4 sports gold, clad short-proof binding posts, premium gold RCA jacks
• IEC cord inlet with external fuse holder completes the function and high quality look.

This is not a digital power amp, class D or familiar digital type. M4 is a full Class AB power amp owing its creation to our Musical Concepts PA-8 circuitry. We use a high bias on our UK sourced Dual-Die power mosfets for a silky low distortion sound. It compares more than favorably to our previous beloved D-75 amplifier.

Some speak to the ‘special-ness’ of a single pair of output mosfets. That quality, the distortion reduction when compared to multiple pairs of even tightly matched devices, yields a smooth, silky sound like our beloved D-75 but at the next level.

Cosmetics:

• Solid, thick aluminum panel construction
• Front to rear effective heat sinks
• Clear anodized front panel is CNC engraved with MUSICAL DESIGN logo text
• Power switch with subtle red LED - they wore out “blue”
• Black rear panel is CNC laser etched for connectors etc.

 

Sound:

• Remarkably true vocal quality, no float, no bloat
• Lightning fast response without fatigue - no etch, eek
• Huge 3D sound stage with engaging focus
• Solid image, no wander - sense of real event unfolding
• Smooth silky but highly defined top, potent tautly defined bass, reveals all the timbral signatures of the original performance

You will be wowed. You have to hear it to believe such sound is coming from this compact amplifier. It’s not magic just ear-approved engineering. To convince you we are considering a loaner program. More info and photos to come soon.

M-4 is officially launching at $2000 (09-16-24),

Good news - Some M4 amplifiers are prototypes with special discounts. An M4S model with switching power supply is under consideration at same pricing. Some prototypes are available at considerable price reductions. The M4S is an excellent amp too. It is light weight and ships free. (09-16-24)

Chameleon Phono Board Update………… is now available. There are new operating points for the gain stages and new cathode caps

 with new bypasses. Listeners report a “panoramic” quality with better micro and macro details. Also a superior octave to octave balance and clarity has been noted. A truer sense of depth and focus has been mentioned with some images closer and others deeper for a more pinpoint imaging quality, a more solid sound stage portrayal.(10-03-18)  And remember there are upgrades to the main boards and individual gain  (Active) boards too in many cases.

Musical Design D-140 and D-150 amp owners…. can now enjoy a striking upgrade in sound quality with our new 7 Series driver boards. Put those aging driver boards out to retirement. See our D-150B amp page. (08-11-18)
