ATTENTION! This auction is for AUDIO RESEARCH AMPLIFIER CLASSIC 60 ONLY!!!!! If you want to by extra AUDIO RESEARCH PREAMPLIFIER SP-14 - See My other auctions.The new Classic 60 Hybrid Stereo Power Amplifier resembles the long-popular D115 in Audio Researchs family of High Definition® power amplifiers. But its lineage is strictly Classic 150. Which means nothing less than state-of-the-art in design, construction, musicality, and operational convenience...at an affordable price. Like the Classic 150, the Classic 60 proceeds from the notion that power ratings dont always describe a power amplifiers real capabilities. Far more important are such qualities as dynamic stability. lucidity, subtlety. And to achieve those, Audio Research has used its traditional partial cathode coupling along with triode operation of the Classic 60s eight 6550 power output tubes. Additional circuit improvements, as well as the usual rigorous parts selection and manufacturing Audio Research, are noted for, also contributing sonically. Translated into the language of listening, this signifies stunning bandwidth, a noise floor virtually beneath audibility, and musically fulfilling SPLs at dramatically lower gain settings. Dynamics, timbres of individual instruments, soundstage, and musical emotion all surge out from a black velvet of silence. Simply put the Classic 60 resolves far more of a musical program than amplifiers rated at two, three, or four times its seemingly modest 60 WPC. But the Classic 60 is easily up to the task of driving all but the most demanding loudspeakers, even in spacious listening rooms. And while it shows modest preamplifiers in their best light, it also shines when coupled with premiere designs, such as Audio Researchs SP14 or SP15. Convenience figures are high on the Classic 60s list of attributes, as well. For example, the DC balance of the output tubes is maintained automatically, while tube biasing continuously adjusts to changes in incoming line voltage. Performance stays razor-sharp without bothersome tweaking or adjustments. And quiet fan cooling, along with triode operation, means significantly longer tube life. A Classic 60 owner can look forward to years of low-maintenance performance POWER OUTPUT60 watts minimum continuous at 16 ohms from 15Hz to 20kHz with less than 1.0% total harmonic distortion. Typically below .005% at 1 watt. The approximate actual power available at clipping: 62 watts.

When Stereophile reviewed this preamp, they concluded it will set new standards for the industry. A quick listen and you will probably come to the same conclusion. Music reproduction was simply magical. Soundstage was large in scale with loads of detail and if you listen to a lot of vocals, the SP-14 is a gem. The level of performance it offered at its $3,000 MSRP then is a bargain now when you look at some of the current crop of $3,000 preamp. Design is a hybrid where one E88CC tube is used. Current tube inside is a Tesla E88CC which is renown for its warmth and overall performance. Previous owner had it serviced when some of the original resistors and caps were replaced. Some browning of the board is from the old resistors over heating but issue is resolved with new resistors. Cosmetically, it looks really nice with minor scuff marks from use but nothing major. Unit will be securely packed for safe shipping. Terms and conditions - PLEASE READ! Changes to PAYPAL refund: Due to recent policy changes at PAYPAL where they will not be refunding their portion of the PAYPAL fees, any refund that is requested to us will be treated likewise. In other words, when you send over a payment, the fee that PAYPAL takes out, will no longer be refunded back to you should you request a refund or we have to do a refund because you did not meet our transactional policy (like asking us to ship to a different address that is on the PAYPAL payment). We know this is unfair and have filed a complaint with Better Business Bureau. Hopefully, they will be able to “persuade” PAYPAL to drop this ridiculous policy. If you think this policy is ridiculous, pls contact your local BBB and file a similar complaint. That will add some weight to our filed complaint.TRANSACTIONS on eBay: ALL transactions must be completed on eBay. NO EXCEPTIONS. We will not respond to offers or suggestions on completing the transaction outside of eBay. Do not ask us to contact you directly outside eBay. If you find an item here on our eBay store that you are interested in purchasing, please conclude the transaction here on eBay.PRODUCT INFO: All items are fully tested and evaluated. If an item is not working properly, it will be mentioned in the listing. So read carefully. Cosmetic conditions will also be clearly laid out in the listing. But because everyone has a different standard, what is an 8/10 condition to me may be a 6/10 condition to you. So it is important you check out every picture on the listing. All pictures are of the actual item and taken just prior to listing it on eBay. All opinions expressed on our listings are our own and based on our evaluation in our system. They are not Gospel truth and should not be treated as such. Every system, every room and every conditions are different. We do not guarantee the result we get in our system will be the same in yours. WHAT KIND OF PRODUCTS WE SELL: We are a used hifi store so everything is used. So no warranty of any kind is offered or expressed. If there is a balance factory warranty from the manufacturer, you should check with them to see if it’s transferable. See above paragraph, everything is tested prior to selling and if there is any issue, we would list it in the listing. So it’s important you read every word in our listing. Occasionally, we may get dealer demo units, NOS (New Old Stock) or dealer excess inventory. Again, you need to check with the manufacturer if they will continue to honor any kind of warranty to you. PAYMENT INFO: PayPal payment is preferred and expected within 3 days after listing has closed. If payment is made through PAYPAL, we will ONLY ship to the address on the PAYPAL payment.

If somehow the item arrives damaged, the buyer will need to inform us immediately so that we can get the claim process rolling. We will assist every way we can to get your money back. But this will be rare as we professionally pack every item that goes out to survive the rigor of shipping regardless of value. All orders will be insured and declared at full purchase value. If you want us to declare it at a lower value, you will need to fill out a form authorizing us to declare it at the amount you want us to and that you will assume all risk at the lowered value. And that includes insurance claim should the package be damaged or go missing during shipping. RETURNS: There are absolutely no returns for any items shipped outside the United States. International purchases for all items are as-is. The buyer assumes all cost of return shipping and handling. The only variation of this is if the item you receive is not the item you bought.

Cost of return shipping is your responsibility. This is a case to case basis and not an outright offer to accept every and any returns back. This is why it is important to read our listing carefully. Everything and anything is described in it with all pertinent information for you to make an informed decision. If you have any questions, ASK! DECLARED VALUE: All overseas purchases will be declared based on purchase price. NO EXCEPTION. This is because;1) For your protection as the declared value is also the insured value. 2) eBay and PAYPAL policies dictate that all declared value must be the purchase or transacted price.We know this may be tough in some countries because of your high duties so we will make exceptions but you need to contact us first and work out the details to complete your purchase.
