As someone who uses a Tandberg receiver to listen to classical stations when I visit my parents in Montreal and a Linn Kremlin for my FM sessions here in NYC, it is nice to see companies still investing in FM. Also nice to see a receiver with enough inputs for those of us who have more than two components to plug in.

Antenna Specialties APS-13 enjoyed a good reputation, but they went out of business a long time ago. I don't think Channel Master or Winegard still offer anything in a good high gain directional outdoor antenna optimized for FM.

What is available commercially? Anything pro-grade, broadcast monitor reference grade?

Are there any credible good DIY designs available?

A brief article covering the subject, including a nontrivial market survey would be an interesting read.

Maybe a little on the techie side, but that's the nature of it all. Brian *REALLY* knows his stuff.

EDIT: I should have read some of the replies below before hitting "Save". Somebody already mentioned this website. Sorry for the duplication. I'll do better in the new year. (Just not post - that's my resolution.)

Timbo in Oz's picture

A rhombic wire antenna on the ceiling pointed at the desired station.

See FM Tuners site. IIRC

IF the station's transmitter is close by, a T antenna pointed at it may suffice. You may need a map to figure out the bearing.

Or mount the T antenna on a narrow strip of wood on a round base and add a kitchen / dining table turntable under it.

Still surprises me that so many folks don't GET that antennas matter way more than the tuner.

Timbo down under as in OZ not Okey!!!

Good question, I am using an old rabbit ears antenna and would love to put an aerial, albeit a small one on my 11th floor balcony, so I can better catch WKCR.

Find a good VHF TV antenna as the FM band is between channels 6 and 7. Most of these will work well depending upon your distance from the transmitting site.

If you are close to a metro area don't forget about the Magnum Dynalab ST-2 omni outdoor antenna. They make some of the best FM tuners on the market.

Also check out https://winegard.com/ I am still using one of their smaller directional FM only older models.

This new Mac receiver is an amazing all in one product. Given what separates cost these days it might even be a bargain.

volvic's picture

I think this is the best option, especially for those who live in NYC Co-op buildings that need something inconspicuous from property manager’s prying eyes.

JRT's picture

Magnum Dynalab ST-2 is omni-directional, so may help improve reception of weak signal, but is not going to help with multipath interference. If mutlipath interference is the problem, then a directional antenna may help.

... residential-grade FM antenna with relatively decent performance seems to be the four-element Stellar Labs 30-2460, sold by Newark/Farnell/Avnet/MCM for $30.
https://www.newark.com/stellar-labs/30-2460/four-element-directional-outdoor/dp/97W3565
http://www.farnell.com/datasheets/2329535.pdf

If you want to order from the UK, a higher-performance option, at a significantly higher price, would be the Innov 88-DES-11.
https://innovantennas.com/en/shop-page/240/26/88mhz-108mhz-broadcast/11-element-88-108mhz-op-desInnovAntennas.html

A professional-grade, broadcast monitor quality antenna would be the Kathrein-Scala CL-FMRX. Last time I checked the price, it was over $1K - maybe not an unreasonable sum if you're already spending $7.5K for a receiver.

Best resource I've found for FM antenna info is the K6STI site:
http://www.ham-radio.com/k6sti/
It includes modeled performance evaluations for many antennas, some suggested mods and a few DIY projects.

The Grimm Mu 1 streamer has an FM Tuner which is promised to be enabled in a future software update. Having FM tuner functionality in a streamer sees like a good idea. Can't comment on the quality of the tuner since it isn't enabled yet.

For the $83K for my pre thanksgiving surgery I could have bought 10 of those and had 9 new friends for life. Just sayin. Glad I had the surgery, though. YMMV.

DavidEdwinAston's picture

Forgive me, nothing technical to add. Although I am perfectly content with my Quad solid state amplification, I want this product, or to be fair, any McIntosh product!!! Surely, that facia appearance must be ingrained into the subconscious of anyone who has heard music on a radio and then grown up attempting to hear it played, as well as possible, in their own homes?
Anyway, thank you for this wonderful online resource, and Happy New Year to you all.

avanti1960's picture

would be mainly interested in the amplifier section of this receiver, thank you for (briefly) capturing its essence.

jimtavegia's picture

$2K less. Would love that as well.

... a US dealer for the MA7200 integrated amp?
According to the McIntosh website, the MA7200 is not available in the US (or Canada).

$5500.00 Another bargain I would think for those in high end land.

Ortofan's picture

... the MAC7200.
The MA5300 does not have the output-coupling autoformers.
For about the same price as the MAC7200, there is the autoformer-coupled MA8900 integrated amp.

I still love it and I would still want the receiver, all in one, and have everything I could ever want and more. By right buy once.

jimtavegia's picture

$5500. Seems like another great buy.

£6750, to purchase this side of the pond!

Why Mac wont invest in Heat Sinks is beyond me , at these prices it should seem possible ..

... amplifier preconditioning procedure from running an amp at one-third power for one hour to running it at one-eighth power for one-half hour?

Why has there been a change made in the amplifier preconditioning procedure from running an amp at one-third power for one hour to running it at one-eighth power for one-half hour?

When Stereophile started measuring amplifiers in the late 1980s, we preconditioned the amplifiers being tested by running them at one-third power into 8 ohms for 60 minutes. With an amplifier with a class-AB output stage, this maximally stresses the output devices, and was the preconditioning originally recommended in 1967 by the IHF (Institute of High Fidelity) and adopted by the FTC.

Many manufacturers argued that this was too demanding and not typical of normal use, so the CEA introduced a different preconditioning: running the amplifier at one-eighth power into 8 ohms for 30 minutes. As current-day designers probably use the more-recent CEA test rather than the IHF test when specifying heatsinks, etc, we recently decided to use both: applying the CEA test, then, if the amplifier didn't overheat, continuing with the older IHF test.

With this McIntosh receiver, it only just passed the CEA test. Continuing with the IHF test would probably have broken it, aborting the measurements.

... incorporates built-in thermal protection circuits to guard against overheating.
It might have been useful to determine if those circuits performed as intended.
For those amplifiers that do pass the CEA preconditioning procedure, if you are concerned that the more stressful IHF/FTC preconditioning procedure might cause a given unit to fail, perhaps you could perform that test after all of the other measurements have been completed.

DavidEdwinAston's picture

and here is me, thinking that a McIntosh product would have the durability, and longevity of granite!
Should you deign ever to test the Quad monoblocks that I use (no longer marketed Platinum.) I wonder how they would fare using the old test?

JRT's picture

Your comment about the product having the durability and longevity of granite seems inappropriate for something with only a non-transferrable 3 year warranty on parts and labor (per the specifications page of this review).

DavidEdwinAston's picture

Excellent point JRT. Perhaps, the hifi electronics with the longest (transferrable?) warranty should always be the go to choice! Hmm, a bit of googling is called for!

JRT's picture

One way to ameliorate some of the risk would be to distribute system functionality across separate devices rather than having so much of the functionality bundled into one disposable receiver. The separates can be separately replaced, so that less is lost when something fails out of warranty and it is discovered that the repair is either impracticable due to some future scarcity of obsolete items needed for the repair, or impractical due to cost and bother of the repair being excessively expensive relative to the cost of replacement or substitution. There is nothing at all new in this consideration, rather is one of the old arguments in favor of separates.

DavidEdwinAston's picture

JRT.
I did have a brief look round. Chord Electronics apparently give a five year warranty on their "full size" electronics. McIntosh may well be above average with their warranty. You know doubt realised I was attempting humour with my granite comment. I would swap my Quads for McIntosh monoblocks in a shot although I likely don't have the shelving space or strength for them!

Hi, my outlaw tuner has HD FM and USA made. That's why I brought it.

rl1856's picture

The MA7200 *is* available to US buyers, and is priced slightly less than the MAC7200. I mention this because FM station choice is problematic for most in the US. Big city or large metro area usually has a few good stations, and a 1 box solution has merit. For suburban and non big city use, a FM radio option may be a waste of funds. In fact the variety of choice, and potential quality from some stations makes internet radio streaming a very viable option. The sound quality of a high bit rate stream rivals or exceeds what is generally offered by FM stations in the US. MA7200 may be the sweet spot for a MAC 1 box solution.

dsmalle's picture

In my country the radio stations are moving from FM to DAB+. It's even become an obligation for new cars to have a DAB+ radio. So I'm surprised when a new receiver from McIntosh with digital inputs doesn't sport this option. It's surely capable for this.

The Stellar Labs 30-2460 FM antenna has all the right ingredients (folded dipole, two directors, one reflector) and the price is right at $30 but does not appear to be available (using Google Shopping). Does anyone have another affordable suggestion?
P.S. this Stellar Labs antenna is large and intended for outdoor applications.

"My other speakers, Revel Ultima Salon2's, were rated by the manufacturer at 3.7 ohms at 90Hz. JA measured its impedance to lie between 3 and 5 ohms, so I selected the 2 ohm tap."
Why 2ohm tap on the Revel Salon 2? Why not 4ohm tap?

In general, the electrical phase angle reduces a loudspeaker's effective impedance, making it more difficult to drive than the manufacturer's specification suggests. The tradeoff with using the McIntosh's 2 ohm output transformer tap would be reduced maximum power but as the measurements show, this was not an issue.
