Review AMPEX Ampexgm ii Us Blank Cassette Tape Basf Super Sound C90 Sealed

Introducing the Ampex GM-II 90-minute blank cassette tape, a high-performance audio recording solution from Ampex, manufactured between 1982 and 1984. This cassette is not to be confused with the BASF 90 C90, although they share some similarities as BASF was one of Ampex's primary suppliers for blank tapes during this period.

The Ampex GM-II blank cassette is designed with a 90-minute recording capacity, providing ample space for extended music collections or comprehensive voice recordings. This cassette employs a chrome magnesium oxide (Chromemix) coating on its 1/4" (6.35mm) wide tape, ensuring superior sound quality and durability.

The Chromemix coating is a proprietary formulation that offers enhanced frequency response, particularly in the high-end, resulting in a more natural and detailed sound reproduction. The tape's oxide layer is coated with a thin layer of chrome, which acts as a protective barrier against oxidation and other environmental factors that can degrade the tape over time.

Additionally, the Ampex GM-II blank cassette features a dolphin-shaped cassette body, which provides increased tape tension and improved contact pressure between the tape and the recording head. This design results in improved sound quality, reduced distortion, and longer tape life.

The cassette shell is constructed of a durable, impact-resistant plastic material that shields the tape from external damage. The cassette is equipped with a reliable, pressure-sensitive record and playback tension arm to maintain proper tape tension throughout the recording process.

Recorded at 1.98 ips (inches per second), the Ampex GM-II blank cassette is compatible with most standard cassette decks and delivers excellent sound quality for its era. This tape is a popular choice among audiophiles and collectors who appreciate the rich, detailed sound and extended recording capacity of this classic format.

In summary, the Ampex GM-II 1982-1984 blank cassette tape is a high-performance audio recording solution with a 90-minute recording capacity, featuring a Chromemix coating, dolphin-shaped cassette body, and durable construction that ensures superior sound quality and long-lasting performance.

This comparison aims to provide an insightful analysis of Ampex GM-II 1982-1984 blank cassette tapes and BASF 90 C90 tapes. Both tape formats were popular during the 1980s, and understanding their distinct characteristics can help individuals make informed decisions when purchasing vintage cassette tapes.

A. Pros

1. High-Quality Sound: Ampex tapes were renowned for their excellent sound quality, which was a result of their high-grade metal evaporated oxide coating and high-tension recording mechanism.

2. Long Recording Time: With a recording time of up to 60 minutes per side, these tapes offered a significant amount of recording capacity.

3. Durability: Ampex tapes were known for their durability, making them a reliable choice for archival purposes.

B. Cons

1. Expensive: Ampex tapes were more expensive than other brands due to their high-quality materials and manufacturing process.

2. Limited Availability: Given their age and discontinuation, finding Ampex GM-II 1982-1984 blank cassette tapes in good condition can be a challenge.

A. Pros

1. Affordability: BASF 90 C90 tapes were more affordable than Ampex tapes, making them a popular choice for many consumers.

2. Wide Availability: These tapes have been more widely produced and are easier to find in various conditions.

3. Good Sound Quality: BASF 90 C90 tapes offered good sound quality, making them suitable for various applications.

B. Cons

2. Lower Durability: Compared to Ampex tapes, BASF 90 C90 tapes were not as durable and may degrade faster over time.

Both Ampex GM-II 1982-1984 blank cassette tapes and BASF 90 C90 tapes have their unique strengths and weaknesses. Ampex tapes offer superior sound quality, longer recording time, and durability, but they are more expensive and less available. BASF 90 C90 tapes are more affordable, widely available, and offer good sound quality but have a shorter recording time and lower durability.

The choice between Ampex GM-II 1982-1984 blank cassette tapes and BASF 90 C90 tapes ultimately depends on individual priorities. If sound quality and recording capacity are top priorities, and budget is not a concern, Ampex tapes may be the better choice. However, if affordability and availability are more important, BASF 90 C90 tapes are a suitable alternative.
