A Tale of 3 Phono Preamps

Musical Fidelity X-LP, NAD PP-1 & Creek OBH-8

The CD reissues of Segovia's old Decca recordings suck: thin, bright and all the ambiance of a telephone booth. In contrast, the original Decca LPs sound wonderful. So, you've got an itch to play your Segovia LPs but your receiver lacks a phono stage. Mass-market manufacturers of stereo preamplifiers and receivers often omit the phono input, reasoning that it's a costly extra people don't need. However, turntables and LPs are more popular than they've been in years, yet harder to mate to new stereo equipment. Fortunately, you can buy an outboard phono preamp to process the low-level signal from a turntable and feed it to your main preamp or receiver. Here is a tale of three budget phono preamps I auditioned.

Appearance & Construction

Musical Fidelity X-LP

The British-made X-LP ($250) is one strange looking phono stage. It resembles a device of mass destruction from a James Bond movie: cylindrical shape, thick brushed aluminum faceplate, red indicator light, semi-gloss black chassis, heavy duty rolled steel body and integral cradle/stand (if you value your freedom, don't take this thing through airport security). I especially like the two Allen wrench sockets on the faceplate. She weights the same as your average brick and is the size of a large can of Boston Baked Beans. The fit and finish are excellent. The X-LP is by far the best looking, built and sounding of the three budget phono stages I used during the past 2 months (i.e., the Creek OBH-8 and NAD PP-1). With its hospital-grade look it ain't your father's little black box.

Did I mention the X-LP is sturdy? You could stand on it without fear of damage. Furthermore, you can bring on your tightest RCA interconnects, the X-LP's back panel will not bend no matter what. The 2 pairs of RCA inputs are gold plated and may be switched between the appropriate sensitivity for a moving coil or moving magnet cartridge. She sports a ground terminal but, unfortunately, lacks a power switch. You'll have to buy the look-alike X-PSU power supply ($200) if you want a power switch (the X-PSU should enhance the sound as well).

NAD PP-1

The PP-1 ($125) is a small black metal box (1-1/2 inches high by 5-1/4 wide by 2-3/4 deep) with a green LED on the faceplate. The input sensitivity is appropriate only for a moving-magnet or high output moving coil phono cartridge. There is no power switch or ground. She sports a wallwart/DC input, a one foot shielded cable with gold-plated RCA connectors and gold plated RCA inputs. My first impression of this Chinese-made NAD is that it is cheap looking. Fortunately, it's so small you can easily hide it.

Creek OBH-8

The OBH-8 ($200) is a black metal box, a little larger than the NAD, and features a pushbutton power switch and green LED on the faceplate. The input sensitivity is appropriate only for a moving-magnet or high output moving coil phono cartridge. A ground screw, 24v input and female RCA I/O are provided on the back. Plain but reasonably good looking. Unfortunately, she also sports a wallwart power supply (more on that later).

Power Supply

There is one thing all three phono stages share: wallwart, wallwart, a cheap little made-in-China wallwart. However, as much as I despise wallwarts, as least the X-LP's wallwart does its job well, i.e., it supplies power and nothing else to the X-LP. In contrast, the PP-1 and OBH-8 sport wallwarts that are excellent radio receivers and, subsequently, will propel inner city dwellers straight into RFI hell. Thank you Musical Fidelity for spending a little more time and money for shielding and/or filter circuits to keep that classic rock station and hum out of my phono stage!!!

Sound Quality

Right out of the box, the X-LP sounded a little bright and irritating. It took a week of large doses of daily vinyl for the X-LP to "break-in," i.e., develop a balanced tone and full sound stage. The Creek seemed to burn-in only after a few days. Amazingly, the NAD didn't need any burn in as it sounded the same all the time (maybe my dealer sold me a demo or return as the box looked beat).

Although both the NAD and Creek sound decent, the X-LP is far better. First, it is RFI FREE!!! This is a big deal as my 31st floor condo is less than 2 blocks away from a transmitting tower. I live with a low hum and classic rock in my telephones, guitar amps and cheap unshielded stereo components.

The X-LP's main attributes are its transparency, detail, smoothness and balanced sound. I hardly noticed that it was there, it merely reproduced the source with clarity and truth. I listened to it for hours without fatigue, unlike a certain Sony CD player I owned.

Chick Corea's "Return to Forever" sounded wonderfully natural and full bodied . Unfortunately, the X-LP's increased detail and resolution over the other phono stages can be a little irritating if your source is poor. A recording I knew to unusually bright, Julian Bream's "Music of Spain, Lute, vol. 1" (RCA, ARL1-3435), sounded edgy but just bearable on the NAD and Creek. However, the X-LP rendered it uncomfortably bright. On the other hand, the X-LP served up Andrés Segovia's "The Castles of Spain" (Mecca DL710171) as one of the most beautiful classical guitar tones I have ever heard: rich, full, round, balanced and not a hint of edginess. The same recording on the NAD and Creek was ok but a bit dull or flat sounding. Yes, rolling off upper frequencies makes bright recordings and surface noise more bearable. However, the downside is that good recordings lose upper frequency detail and sound a little flat. The X-LP gives you the whole deal, i.e., the good, bad and the ugly.

The X-LP has a wide, deep sound stage. Chick Corea's "Return to Forever" sounded huge compared to the other phono stages. Unlike the other phono stages, the X-LP allowed me to shift around on the couch and still remain in the "sweet spot" and hear the position of instruments in the ensemble.

Snappy dynamics were no problem for the X-LP. The NAD and Creek both compressed the signal a little during sforzandos in symphonic recordings or percussion accents. The X-LP let me feel every whack of the conga drum when Irakere (Columbia 35655) played Misa Negra. The X-LP seems to have plenty of headroom and thus accurately rendered both perky and pounding dynamics without smashing the sound.

If you give the X-LP a good recording on a clean record the detail and beauty of the music are astounding for this side of $250 (only $50 more than the Creek OBH-8). The X-LP is good looking, built like a tank, well shielded and sounds excellent. What a bargain for the demanding music lover on a budget. I returned the NAD and Creek but the X-LP is a keeper. Maybe I'll lose the 'wart and buy that cute little matching power supply later.

Update • 7/14/2001

The X-LP was replaced with the X-LPS late in 2000. I needed a phono stage for another turntable so I bought it. After a couple of weeks of burn-in, I compared the X-LP to the X-LPS. They look exactly the same, but the X-LPS is a little smoother sounding with no apparent loss of detail or fullness. Specifically, the lower highs are rolled off slightly thus reducing edginess on overly bright recordings. The soundstage seems a little larger as well. A nice improvement. Oh, the price is the same and no RFI!
