Q: I have a Neuhaus Laboratories T-2 tube amplifier connected to Martin Logan speakers. I need something that will receive Bluetooth music from my iPad and play it back through the amplifier. Do you have any suggestions?

A: The simplest and easiest way is a Bluetooth receiver connected to an analog input on your T-2 amplifier. The Amazon Basics model will do a decent job and costs only $20. It can be used to add Bluetooth capability to any audio component with an analog input.

That's a nice amplifier you have, by the way. I recommended them for years and have one myself.

No more stacks of wax

Q: Do they still make stackable record players where you can put several records on a spindle and they play one after another?

A: What you are thinking of is commonly known as a record changer. Decades ago, when vinyl records were dominant, record changers were common. They were usually found in stereo consoles and stand-alone, single-piece record players. There also were a few component record changers available, designed to be used with a hi-fi system. There were concerns about record wear because of the uneven platform created by the discs stacked on the turntable, however, so no audiophiles worth their salt would have been caught with a changer.

I don't know of any changers that are still being made today because there is not enough market demand for them. If you must have a record changer, look for a Garrard component unit, preferably one that has just been serviced. Prices typically start around $150 on eBay. BSR made a few models as well. They are not quite as good as the Garrards, but they cost less.

Surround sound setback

Q: My wife and I just downsized/moved to a different home.

In my old house I wired up a nice surround sound system for my TV. I used my Yamaha receiver, three front speakers, two rear speakers and a subwoofer. All speakers are Infinity. Everything was wired through my crawl space and sounded good.

The new house is one story and on a slab, making wiring very difficult. Plus, the Yamaha with my large KEF audio speakers is physically too big for the living room. (I have other plans for those.)

I did a little research and came across the Nakamichi Shockwafe Elite system that includes a center soundbar, two 8-inch wireless subwoofers and two rear speakers. The cool part is the rear speakers then plug directly into the wireless subwoofers. VoilĂ ! They tout the two subs as giving better bass distribution. But Nakamichi is not cheap and sells everywhere for $799.

Do you know anything about this system? Do you have any other suggestions?

A: I have not heard this system, but after receiving your e-mail I did some research and it does seem to be the real deal. If you have a healthy budget for a surround system and want something that is soundbar-based, the Shockwafe looks to be a winner. (nakamichi-usa.com)
