These beautiful rare monsters arrived some time ago into our shop and we've really enjoyed listening to these in our listening room... but after a lengthy internal debate we decided to remove them from our Not For Sale collection and JUST listed for sale.

Originally released in 1993 to the tune of $35,000 - which in today's dollars equals $62,299.52!

These amps were serviced by Krell by the previous owner and have been boxed up and unused ever since.
This listing is for a complete set, including the original boxes & packaging, Manuals, Tools, Connectors, etc.  

We received them a few months ago and tested them thoroughly in our lab using our standard amplifier testing procedure, where they passed with flying colors. 

Cosmetically they are near perfect with no signs of wear or use. They might have an occasional light scuff from handling, but I wasn't able to locate any at the time of writing this. 

The meters are bright and responsive, and the metal work is intact with no fading of the finish on the heat sinks as they sometimes turn to a deep purple on amplifiers from this era. 

We have the original double cartons (yes all four of of them) and all the packing materials that will ensure safe travels. These will ship on a pallet via freight. 

Assembly is well detailed in the manual as there are a number of connections that need to be made between the two chassis. 

There are also spacers that need to be installed between the amps that allow for proper distance so the connections are easily made. 

Lastly there is a protective cover that needs to be installed in order for the amps to turn on (we found this out the hard way since we did not read the manual).

From Wes Philips over at Stereophile:

"The Audio Standard is a double-decker amplifier: its regulated power supply occupies a chassis separate from, and equal in size to, that holding the audio circuitry. The power supply has an LED readout (which can be turned off) that displays the voltage coming out of the wall. The audio portion of the amp—the top deck—features a large oval meter offering a variety of illumination and readout configurations."

If we don’t have the original manufacture's packaging, we use heavy duty double ply corrugated boxes with Instapak expanding foam custom inserts.  In many cases this has proven to be better than the original packaging.  We also use high quality fiber reinforced tape to seal our packages.  Lightweight items will be bubble wrapped and shipped in a high-quality box. 

This item is available for pickup in Glen Rock with convenient parking near our building.

NJ Residents or anyone picking up without a resale certificate will need to pay NJ Sales Tax.

SkyFi Audio 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, 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 very selective 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, Pro-Ject Audio Systems, and Sony ES, we have access to OEM parts, service, and support.  If you are local and looking for new equipment from the above-mentioned manufacturers, please drop us a line as we can arrange both sales and professional installation in the tri-state area.


We do not accept or review any offers that do not go through the official Audiogon system. We have too many items for sale and it’s nearly impossible to keep track of offers outside of the official system. Please don’t message, email, or text any offers. 

If you do not see a “Make an Offer” button, it means we are not considering any offers on that item.   


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 if you purchase the item at the asking price.  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. 

If you are picking up an item we do not accept PayPal.  You must pay in person with cash, certified or bank check, or wire transfer.  If you make a PayPal payment and are picking up the item, it will be returned. 


We accept trade-ins of equal or lesser value under certain conditions.  Simply ask and let us know the exact model, condition, and the accessories that are included (such as the original box, remote, cables, 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 surround 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 resell 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 on your own.

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 our shop located in Glen Rock, 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.

You can call 201-879-0000 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’re local to our area.  This is super useful when purchasing large speakers or heavy amplifiers.  It’s also great for ensuring your new turntable is setup correctly in its final resting place.
