Krell KRS1-a 4 Piece Preamp




Designed and built in the late 80’s, the gold age of high end audio, the KRS-1a was a “cost no object” flagship references preamp from Krell. 



This is a dual mono design and I mean DUAL MONO, not just two separate signal paths in one box but actually two completely separate and unconnected boxes, one for each channel.  It was common to have a two piece reference preamp, one housing the power supply and the other the preamp section but a 4 box version was unheard of.  



I addition the KRS1-a uses the highest quality components available at the time.  It is fully analogue without any complicated integrated circuits or proprietary components.  This makes the unit super easy to service and likely to last for decades more.  



When the unit arrived at our shop we quickly got to replacing every single capacitor in the preamp section.  Thats not small feat as there are over 120 capacitors.  Unfortunately most capacitors will age, bulge and leak over time and this unit showed some signs of it being a problem in the future so we went all out and replaced them all. We even serviced the phono boards.  This is a laborious and tedious endeavor but well worth the investment for a piece of audio history of this caliber and rarity.  Do not buy a unit like this that has not been fully service and you will cringe when you get the bill for service.  We used the highest quality Nichicon capacitors we could get our hand one.  



As expected this unit comes with super high quality Krell phono modules internally installed. There are micro switches locate on the boards that allow for no less than 10 loading values.   There are also adjustments for a feature we have never seen before on a preamplifier.  Internal you will find micro switches which select which type of CD player you may connect to it.  They call it a 3 pole phase correcting filter which is set to match the type of CD laser used in your unit like Phillips or Sony.  Very cool option.  



After service the unit was deeply tested on the workbench before making its way into our dedicated listening room where is blew the doors off any preamp we have ever had the pleasure of using.  Yes the dual volume adjustments take a bit more effort than a single potentiometer but the extra trouble results in the best imaging and channel separation we’ve experience. 



Cosmetically the unit is in amazing shape considering the age.  There re no noticeable or deep scratches or dents.  There are a few light marks here and there but nothing worth mentioning and only visible upon very close inspection.  All the writing and engraving is in perfect shape and there are not signs of use or abuse.   The gold plated connectors are super clean and the knobs all operate precisely and responsively.  



Dont miss the opportunity to own this piece of history sure to appreciate over time as more and more audiophiles realize the benefits of a full analogue preamp.  



Included are the 4 pieces, the two umbilical cords and two power cables and original manual.  



The item will be professionally packaged and insured for safe transit to your home.

PURCHASING GUIDELINES


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.   If you don’t see a “offer” button its because we are not taking offers on this item.  Please don’t bother to make one.  



PAYMENTS


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.
