Purchased a vintage Muse 100 in decent shape for $450 - I owned one back in the day when I sold Hi Fi in the SFV CA.

I remember the amp sounding tube like, but with great bandwidth - but hearing the amp today, it sounds even better than I remember!

Dynamic, fluid, and the bass is outstanding. You can tell the amp has a good power supply and current. LOL Maybe its nostalgia, but I am loving this amp!!

Any Muse lovers/haters?

That's is really great when an older amp exceeds your positive memory of it in the day. Nice!

I owned the bigger brother Muse Model 160 for several years in the 90's - great amp!

As everyone who follows me knows, my first "expensive" audio product was the $1200 (in 1991) Muse Model 100. What a disappointment this turned out to be.

First of all, it needed a cheater plug on its fixed powercord. Otherwise, it sent a LOUD 60hZ hum through my speakers. Even powerline conditioners from the likes of Adcom, API, PAC, Tice, and Vans Evers could not, on their own, solve the Model 100's ground loop hum.

The heatsink fins were sharp. They sliced many a wrist and forearm.

My unit did not have any feet. Therefore, I was forced to buy after-market footers - another added expense.

For a solid state amp, the Muse Model 100 ran hot, which required ventilation space.

The Model 100 had this cheesy red power switch, which glowed red when on.

When I got the Muse Model 100 converted to "balanced" XLR, it was configured with pin-3 positive, opposite of most other balanced gear.

Sonically, the Muse Model 100 sucked. Even with the finest upstream components and cables, the Model 100 lacked transparency. Others blamed the "MOSFET mist," but there was a distinct fuzzing up of images.

As I and my guests lost interest in the music (because the Muse Model 100 threw away the sources' information and resolution), we pressed STOP, and then furrowed our brows. Guess what? When everything else was silent, the stupid Muse Model 100's transformer hummed/made a buzzing noise.

The sucky Muse Model 100 inspired, or gave me incentive, to write audio reviews. Unlike others, I actually do cover the all-important topics of heat, ergonomics, aesthetics, features, specs, and compatibility.

I had a similar experience many years ago. I purchased one after the rave reviews and had the hum issue as well. Sharp heat sinks, red power switch, overall it was not a great experience and I sold it and moved on- Llano Trinity, Music Reference, Bel Canto, Odyssey Audio and now Modwright. None have had hum issues or any other issues that led to selling them. They all had their strengths and I enjoyed them all, different tonal qualities and characteristics. Only the Muse brings back a negative memory.

Interesting. Friends had Muse 100's on Vandy 3's, and it sounded flat, distant, and lean, with really no bottom end at all. I brought over a modded cj75 for a day, and they came to life, even though the bottom end of the cj was a little on the floppy side. They ended up with Premier 12s, which today are driving their lovely Quatros.

I am glad I found this thread. A few months ago I was looking for a used amp to buy. The Muse was one of them. I ended up getting a Forte Model 3 (200w a channel) and I am glad I did......

Apparently, a very polarizing amp! Love it or hate it!

Meanwhile, I'm listening to my Reference 3As and the Muse 100s and no hum. Just glorious music - and better bass than most any amp I have heard. full and harmonically rich, but not flabby. Liquid mids and extended highs - but perhaps a bit rolled off the top to accentuate the tube like aspect of the amp.

No wonder the reviews compared it favorably to the Counterpoint and VTL TT25 amps...that is what my ears are experiencing.

or maybe just QA issues, based on some other posts here... see the linked review from Stereophile. I owned the Spectra 1100's for over a decade, and though I didn't own the Model 100 from Muse, I did at one point own the Muse 160 for several years and it was excellent. Your listening notes pretty much mirror my own memories of the 160.

I received the Muse Model 100 in November 1991, and had it for years. Because I had it for so long, and during the time high-end audio experienced explosive growth, my Model 100 was used with hundreds of associated gear. Let me share some of those experiences, from which readers can learn.

When I auditioned Muse gear, I saw it in both black and silver. Because I was a Stereotypically Stupid Audiophile, without thought, I ordered mine in the ugly black. The silver faceplate wasn’t nearly as offensive looking. So that was my first regret.

Obviously, speaker choice is of utmost importance. It wasn’t until the mid-90s, did I find decent speaker matches for my Model 100. Powered by the Model 100, my NHTs, original Sonus Faber Concertino, and Totem Model 1 were the least messed-up.

I didn’t have them side-by-side, but the pseudo balanced (XLR) Muse Model 100 seemed to have higher gain, which only exacerbated the system-wide problem of the volume being too loud, even when the preamp’s volume control was at or near MIN. Furthermore, I thought the balanced version sounded worse. Though the balanced version was marginally more open, PRAT suffered. It did not lock in the music’s snap and pop. I regret not sticking with the regular single-ended RCA version.

Choice of powerline conditioner is critical. Some can even, without use of a cheater plug on the Muse Model 100’s powercord, solve the ground loop hum problem. I recommend getting a PLC which is not colored. And they don’t have to be expensive. For example, the relatively uncolored PAC IDOS and Tara Labs PM/2 worked well.

I did experiment with placing anti-vibration devices on top of the Muse Model 100. The Bright Star Audio Little Rock sucked out the music’s air, and deadened rhythms. A Shakti Stone did not seem to introduce any negatives, and did seem to smooth out the sound. No, the Shakti Stone did not eliminate or quiet the transformer buzz. It only altered the buzz’s pitch. The audiophile who took the Muse Model 100 from me reported that Mapleshade brass weights could clean up the Model 100’s sound, without messing up the music’s energy.

In the early-90s, I used SIMMS Navcom Silencers ($60/set of 4), which were quite good under the Muse Model 100. But for better focus and a leaner tonality, the Michael Green Designs brass cones were more effective. Obviously, you guys can go hog wild, experimenting with bases and footers.

I tried many interconnects (starting with AQ Quartz) on the Muse Model 100. Since the original XLO Signature interconnects were uncolored, fast, and transparent, they allowed my Model 100 to perform its best. But those interconnects cost more than half of the Model 100 itself. For $390, the Kimber KCAG was an excellent match for the Model 100. And that was before we had proper cable burn-in devices, such as the audiodharma Cable Cooker. As we now know, the Cable Cooker removes a lot of the KCAG’s grain, hardness, and fizz.

My unit came with bare copper Cardas binding posts, which seemed to dull as soon as I took the unit out of its box. Over time, the Model 100’s sound seemed to dull, too. Anyway, even when I used a wrench, these Cardas binding posts did a poor job at holding down the spades found on my AudioQuest, Kimber, and MIT speaker cables. They were much happier with banana plugs. With the Kimber KCAG upstream, the Model 100 in many ways sounded best with banana-terminated 4TC. And that was with the mid-90s blue-and-black 4TC. The current-production white-and-clear 4TC sounds cleaner and clearer.

In the Model 100’s heyday, it did not have after-market fuses. Personally, I use Hi-Fi Tuning Supreme fuses in my systems. If the Supreme does to the Muse Model 100 what it does for the rest of my gear, go for it!

Just curious, what amps have you tried and liked - without all the tweaks. OK maybe power cables and ICs :)

In the late-90s, when I still had the Muse Model 100, I had replaced my living room's AC outlet with after-market jobbies from Acme Audio, PAD, and Wattagate.

Today, I use cryo'd and Cooked Oyaide SWO-XXX and R-0 outlets. These are even better than the Acme Audio, PAD, and Wattagate outlets of yore. No doubt, the Muse Model 100 (and the rest of the system) would benefit from an SWO-XXX or R-0.

Go to my homepage, which I've done since 2005. It includes a small sampling of the myriad amps I've lived with. Amps don't live in a vacuum. They are at the mercy of the room and the rest of the system. All an amp should do is take the signal it is given, and deliver it to the speakers.
