Mark Levinson 33H
Legendary reference monoblock amplifiers from renowned US maker Mark Levinson (Made in the USA).
Although they are conservatively rated at 150W per channel, they are able to deliver over 250W as long as your AC outlet can handle it. These are Stereophile Class A recommended components of the highest quality and performance. Originally sold for close to $20k. Quite possibly the last amplifier you will ever buy.
The form factor is unique as they take little floor space and can be placed next to the speaker in order to use the shortest speaker cable possible.
There are several options on the back to manage the power on/off state of the amps including Mark Levinsons proprietary communications port and 12V triggers.
In addition you'll find single ended and balanced inputs as well as a dual set of speaker terminals in case you'd like to bi-wire both ends of the cables.
Condition is very good with no sighs of use or abuse. There are no significant scratches or dents and the pain/coatings are super clean.
The capacitors have been serviced by an authorized service center and are ready for another 20+ years of trouble free operation.
Units will be professionally double boxed for safe arrival. Local pickup in Ridgewood NJ or Union Square NYC is welcomed.
Finally, the big Levinson is a powerhouse of an amplifier, comfortably exceeding its rated power. Specified at 150W into 8 ohms, it actually didn't clip (defined as 1% THD+N) into that load until 265W (24.2dBW)! And the wall AC supply, at 114.5V, was starting to droop—this means that, with its own dedicated 30A line, this amplifier will probably put out 300W into 8 ohms.
Fig.8 Mark Levinson No.33H, distortion (%) vs output power into (from bottom to top): 8 ohms, 4 ohms, and 2 ohms.
Into 4 ohms, the maximum output power almost doubled, to 500W (24dBW); into 2 ohms, 900W was available (23.4dBW). (The wall AC voltages for these power figures were 113.3V and 112.5V, respectively.) As we don't have a dummy 1 ohm resistive load capable of sinking the almost 2kW that the Mark Levinson is presumably capable of putting out into this load, I wasn't able to check its clipping power into 1 ohms. However, the fractional decibel drop in dBW each time the load is halved suggests that this amplifier behaves as an almost perfect voltage source.—John Atkinson

WHO WE ARE
Skyfi.nyc is a small startup business specializing in the purchase, reconditioning and reselling of select high end audio equipment. We only buy equipment the we admire and are passionate about. No mid-fi, no gimmicks and no junk.
Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the Hifi world. If it does not meet or exceed the original manufactures specifications, it will not be sold. We are select about the equipment we purchase, focusing on mostly analog, high-build quality, American and European built units.
Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project and Sony ES, we have access to OEM parts and service support. If you are local and are looking for any new equipment for the above mentioned manufacturers, please drop us a line as we can arrange both sales and professional installation in the tri-state area
If you would like to make an offer, please don't email or message us unless you are looking to trade something in.
If we are accepting offers, you will see a button on the listing page to do so. Please use it, as it is very hard to track offers through email or messaging. This way, we are all also better protected.
We prefer working through PayPal, which allows you to use a credit card or bank transfer. We do not charge extra for any payment fees. You can also send us a personal check (which will need to clear before shipping), certified check, money order or wire transfer. International clients without access to PayPal should use a bank wire transfer.
TRADE IN POLICY
We accept trade-ins of equal or lesser value under certain conditions. Simply ask and let us know the exact model, condition and what accessories are included such as a box, remote, manual, etc. We will only consider high-end equipment from mainstream manufacturers such as McIntosh, Mark Levinson, Audio Research, Krell, etc. and will typically pass on displays, projectors, receivers, dated processors and mid-fi equipment of any type. We will offer a fair value for your equipment, but keep in mind we are running a business and will need to be able to sell the equipment at a profit after investing a great deal of time and resources in testing, certifying, repairing, cleaning and packaging the incoming equipment. If you are looking for top dollar we suggest attempting to sell it directly to an end user.
SELL US YOUR GEAR (Working or Broken)
We will also purchase your used or broken gear and arrange pickup if you are in our local market. Just drop us a note for a quote, but be sure to include the condition and what is included.
HOW TO VISIT US
We are currently operating from a residence in Ridgewood, NJ. You are welcome to make an appointment if there is a piece of equipment you would like to see in operation before or after purchase. We have a well-equipped, dedicated listening room with tons of equipment of all makes and models. We are not a store, so please don’t make an appointment if you are just curious as to how a speaker or piece of equipment sounds. In essence, no tire kickers please.
If you are in NYC and cannot make it out to Ridgewood, we can arrange pickup in Union Square (14th Street) after the purchase. You can call or text (646) 852-2073 with any questions or to schedule an appointment. We can also arrange to install, calibrate and tune the gear in your listening room if you are in the local area. This is super useful when purchasing large speakers or heavy amplifiers. It is also great for ensuring your new turntable is setup correctly in its final resting place.
Thanks for looking and please send us your email address if you would like to receive a list of the equipment we receive from time to time. We promise not to bombard you with junk email.
