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. The 5050 is $2K/pair.

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 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:
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:
Sound:
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)
NEW! Matching Preamp soon!
Are we working on the P-1…… companion preamp to the M4? You bet and it is stunning.(09-16-24)
SP-1/2/2B preamp upgrade changes……….are listed here. (04-20-20)
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)
SP-1/2/2B Upgrade………. time is here. We have now developed two levels of outstanding upgrades. The dynamics, naturalness, clarity and bass performance is a joy to the audiophile heart. See the details. (08-11-18)
