Safety Tips

For Buyers

  1. Always meet the seller at a safe location and inspect the item before purchasing. Following this one rule will help you avoid most scams.
  2. Watch out for unrealistic offers. If it appears too good to be true, it probably is. Unrealistic offers are used to motivate purchasers to make hasty decisions.
  3. Always verify the seller's credentials. Ask the seller to provide a photo ID and proof of address.
  4. Ensure that the product you are buying is not stolen or fake. Always ask for a purchase invoice.
  5. The best way to transact is to collect the item and pay at the same time. Never transfer funds or use a debit/credit/atm card to pay someone you do not know before collecting an item.
  6. Ask for clear information on condition of the item, price, payment and delivery method.
  7. Use only those payment methods that you trust and are familiar with. Never give out your financial information.
  8. It is recommended to purchase items directly from the seller.
  9. Always test the functioning of the item before purchase.
  10. Do your research on comparative prices for the product.

For Sellers

  1. Try to take the full payment at the time of the delivery. Remember to use a safe location to meet.
  2. Watch out for fake currency and money orders. Be aware that banks will not honour fake currency/money order and will hold you responsible for it.
  3. Verify the buyer’s credentials if necessary.
  4. Ensure that your product meets the features you list in your ad to avoid any misunderstanding with the buyer.
  5. It is your responsibility to prove that the product you are selling is genuine and not stolen by providing the necessary proof of purchase.
  6. Do not share your financial information except the one required for payment.

Do you want Isolation transformers for av receiver

Hi gowmara...

I was looking to add a cvt + ultra isolation transformer to my setup to get clean and unrestricted power.

A smaller capacity 500 va cvt + isolation transformer on a dedicated line for sources, dacs and pre amp.

And a larger capacity 5 kv cvt + isolation transformer for a dedicated line for power amps.

I live in a apartment. And luckily my main power / fuse board is in the corridor outside. So plan is to mount these transformers there and draw dedicated power lines to my system in my daughter's bedroom from here.

Hi Newlash basically there are few caveats in the above scenario

1. You are talking about Isolation transformer for the entire house which any of your appliances in the home cannot benefit from the isolation you get from the isolation trafo as any other equipment in the house has smps or bad psu will contaminate your audio gear. Any Ferro based transformers rob the dynamics of your music.

2. Using a 3KVA requires a very specific type of softstart and its not conventional its 3KVA based Isolation transformer and hence will draw massive inrush currents in the beginning which needs a highend softstart system with industrial grade inrush suppressors. If not it will either blow the fuse of the entire apartment which is connected or the dimming of the equipment or TVs or computers in others apartments will get turned off whenever there is a power turn on.

3. Isolation transformer works only for certain band in about 1MHz at max zone but all your RF noise beyond 1MHz still enters into your system.

4. If you are using for HT and music there is one power conditioner from InventionAudio at 3.8KVA which serves your purpose which works broad band. There are users from Hyderabad who have already tested and auditioned the power conditioner.

Its just my tip to make you understand better sound quality from a well engineered product.
