--
Welcome! You are visiting one of the best places on the web to buy and sell classic audio equipment. We're not just speaker designers, but collect classic equipment ourselves and always have quite a bit for sale or trade. We're always happy to correspond with other collectors and to offer advice to those who need it. Come in and have a look around!
And please visit our webpages (links at the bottom of this page) for Audio Nirvana, PAudio, Lowther, and Fostex 'pointsource' fullrange speakers. These are among the best sounding speakers in the world AT ANY PRICE and start at only $98/pr. The minimum efficiency is 100 db for 1 watt!
--We DO NOT sell garage sale, Ebay, flea market, or pawn shop junk! Our equipment is usually from the original owners. It is not modified, but in original condition. Repairs, if any, are usually limited to one or two parts. Almost all the equipment we acquire is 'excellent' to 'mint' when received. Because we are collectors, we refuse to purchase equipment in 'poor' or 'fair' condition. We also don't buy or sell poorly designed or 'cheap' audio equipment. Sure, you may be able to find some of this equipment for less, but ask yourself how much time, energy, and money you'll have to spend to make it right. And who else offers a money back guarantee--no questions asked--on equipment up to 60 years old?
--All equipment has been cleaned, all switches and tube sockets lubricated, tubes (if any) tested or replaced, and all dial lights and indicators are working. The unit has been thoroughly checked out through listening tests. This process can take three hours for an average piece of tube equipment. Do you really want to take the time to do this?!
--All items, EXCEPT SPEAKERS, come with a 10 day money back guarantee. You are only responsible for shipping charges. Because of the time and effort required to package speakers, and their fragile nature, we cannot offer the return policy on these. However, we guarantee the drivers in the enclosures. They can be returned within ten days for repair or replacment.
--Literature is not returnable for obvious reasons.
--Condition is rated as new, mint, near mint, excellent, very good, good, fair, and poor.
Shipping
In the US, we usually use FEDEX Ground. However, for large or heavy shipments--and for most speakers--we prefer to use BAX Global. For international shipping we usually use the post office or BAX Global (which has very low shipping rates). For larger shipments, we use Carotrans International for ocean freight. Their rates are very low.
Methods of Payment
US Customers: We accept credit cards, Paypal, Bidpay, bank checks, money orders, or personal checks (with sufficient time to clear). We charge only the actual shipping costs.
Foreign Customers: We accept credit cards, Paypal, Western Union, Bidpay, International Money Orders, or wire transfers direct to our bank. We charge only the actual shipping costs.

SUBWOOFERS
We have several excellent HSU Research subwoofers that we have used to give demos with our custom speaker designs. These have very little use and are in 'like new' condition with the original box and manual. If you're not familiar with HSU Research, they offer the best 'true' subwoofers in the world for the price. You would have to spend more than a couple of thousand dollars to get this much performance from another company. These models are round and look like end tables. The amplifier can be placed next to your listening seat or with your other electronics. These have all the performance you will ever need for home theater and/or music.
