GRAHAM SLEE SOLO HEADPHONE AMPLIFIER

The Graham Slee Solo headphone amplifier is the choice of several studios and editing suites for one very important reason - the Solo headphone amplifier makes it easy to hear the editing cues. These are musical cues that are part of the performance, but they happen so quickly that lesser headphone amplifiers are not able to resolve quickly enough and thus mask. This makes the editing suite's job very difficult indeed. The wide-bandwidth performance of the Solo headphone amplifier reproduces music with the highest resolution. Coupled with its excellent dynamics, the Solo headphone amplifier is the obvious choice for the professional user or for the pristine listener who wants to hear music as it was originally recorded.

Through the years the Graham Slee Solo headphone amp has received awards and accolades for its sound quality excellence.

Grado 8MZ for my older ZF1 Grado cartridge

Grado 8MZ for my older ZF1 Grado cartridge Fits like a charm and sounds awesome, clarity and great bass and highs and lows. Great choice for alternative stylus .

All good

Great service!!

Waiting still.

The belt just crossed the Canadian border today. It may take another week before getting to my home. Wait and see...

I haven’t receive my order yet. Still waiting

Saved a wonderful turntable and cartridge

I found a Dual CS508 ULM turntable at the local Thrift Store. It still had the AT cartridge installed utilizing the Dual 1/2" adapter. I made a simple repair but upon testing, the cartridge had no output. I removed the headshell adapter and found that "fatigue" had cause the adapter to crack causing a loss of contact with the tonearm connection. I had bought to 1/2" adapters from ebay and transferred the AT cartridge to the new adapter and mounted it back on the tonearm. The turntabled played perfectly. As a matter of protocol, I ordered a new stylus from LP Tunes that fit perfectly. Thank you for still having this stylus in stock.
