I just wanted to post a little tidbit of info I found regarding the "Telewave" wavetable devices.
As gerwin mentioned earlier, this page refers to the Televideo WaveImpact 32 daughterboard and it has pictures of it:

It says the QS501 is made by AdMos or Opti, which fits with the rest of the QSxxxx wavetable chips out there.
In the pictures, it definitely appears to have the same exact QS501, QS502 and QS503 chips as those found on the Televideo Telewave 32 and the Diamond card borichka posted.
I then found this article from 1995:

San Jose, California-based TeleVideo Multimedia Inc – the new name for TeleVideo Systems Inc (CI No 2,498) has a new TeleSound Pro 16 sound board and waveImpact 32 wavetable synthesis daughterboard. The WaveImpact 32 daughterboard delivers high-end wavetable and MIDI upgradability for TeleVideo’s TeleSound Pro 16 and most 16-bit sound boards with a standard wave connector. The TeleSound Pro 16 features high fidelity 16-bit 44.1KHz CD quality stereo sound, Sound Blaster compatibility, and general MIDI compatibility. The WaveImpact 32 signal processor wavetable synthesis daughterboard features 16 MIDI channel and 32 note polyphony support, digital sound recording, full MIDI compatibility, Roland MPU-401 compatibility, wavetable ROM and professional-quality MIDI sequencer software. The WaveImpact 32 daughterboard gives TeleSound Pro 16 and other FM synthesis audio card users an upgrade path to wavetable sound. The card adds 128 instruments and 51 percussion sounds to existing 16-bit cards and is capable of 32 tone polyphony. The WaveImpact 32 daughterboard plugs into any 16-bit FM sound board with wave connector and features signal processor wavetable synthesiser, 16 MIDI channel and 32 note polyphony support, Roland MPU-401 compatibility, 2Mb Wavetable ROM, Voyetra MIDI Orchestrator Plus sequencing software. Both TeleSound Pro 16 and WaveImpact 32 list for $130 and are available immediately.
So, it seem that these cards not only support, but do in fact have 2MB sample memory. Not that the size necessarily makes it better than others, but I haven't found this information explicitly stated anywhere else so I figured I'd mention it. 😀
Now for some blitting from the back buffer.
